Right hip dislocation. We do not endorse non-Cleveland Clinic products or services. A complete history and physical will clue the health professional to the cause of dislocation (post total hip replacement vs native) and the type (posterior vs anterior).2-4,21 A physical examination is crucial in the workup of a suspected hip dislocation. The hip is a ball-and-socket joint that is inherently stable because of its bony geometry and strong ligaments, allowing it to resist significant increases in mechanical stress. However, an estimated two-thirds of patients can be successfully managed with closed reduction followed by external bracing.29 When closed reduction fails or instability persists, invasive methods include exchanging prosthetics, use of large femoral heads, use of dual-mobility implants, and/or use of constrained liners.29,36. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Anterior hip dislocation is commonly reduced by inline traction and external rotation, with an assistant pushing on the femoral head or pulling the femur laterally to assist reduction. A hip dislocation is a medical emergency. Anatomic components contributing to the hip's stability include the depth of the acetabulum, the labrum, joint capsule, muscular support, and surrounding ligaments.1 The major ligaments stabilizing the joint from directional forces include the iliofemoral ligament located anteriorly and the ischiofemoral ligament located posteriorly. People with hip dysplasia have shallow hip sockets, which dont hold their joint in place as well as normal hips do. Figure 27.4. definitive fixation of the femoral neck. The patient is in the lateral decubitus position with the ipsilateral limb facing up. Bone Joint Surg. The purpose of this retrospective study was, therefore, to evaluate it on a consecutive series of 50 FAI patients treated either by arthroscopy (n = 29, aged . The hip is a ball-and-socket joint. Following reduction, the surgeon will request another set of X-rays, and possibly a computed tomography (CT) scan, to make sure the bones are in the proper position. Congenital dislocations result from the physiologic position of the fetus in utero pressed against the abdominal wall of the mother, with the additional component of the posterior force acting against a dysplastic hip joint in flexion.6 Both factors together result in a partial or complete dislocation in a neonate; however, this topic is beyond the scope of this paper. The location of the femoral head depends on the situation of the hip and the resulting forces at the time of injury, thus the superior anterior hip dislocation is produced by forced abduction, external rotation and extension of the femur. 2011 Mar. The majority of all hip dislocations are due to motor vehicle accidents. Hip dysplasia is also called developmental dislocation of the hip (DDH).

Usually, in late dislocations, the polyethylene has worn so that reduction is possible. Reduction of native hip should occur within 6hr due to high risk of avascular necrosis Hip prosthetic dislocation is more common and less emergent High-energy trauma is primary mechanism for native hip dislocation Dashboard impact, fall from height, sports injury Low-energy trauma can cause hip prosthetic dislocation 2010;68(2):91-6. The patient lies supine and the operator holds the knee flexed at 90 degrees. Most authors recommend an immediate attempt at a closed Tulsa technique/Rochester method/Whistler technique. (, 28% after revision and implant exchange surgeries, 70% of dislocations occur within the first month and 75-90% posterior, Associated with other injuries in up to 95% of traumatic cases (, Inablity to move the affected lower extremity, Anterior Dislocation: mildly flexed, abducted and externally rotated, Posterior Dislocation: flexed, adducted and internally rotated, Complete a full trauma survey given frequency of associated injuries, Direct particular attention to ipsilateral joints given the large force transmitted through the lower extremity to cause the dislocation, Ipsilateral knee, patellar and femur fractures are common co-injuries, Meniscal and PCL injuries are common with dashboard type injuries. A hip dislocation is very painful. If only 2 people are available, this technique can still be completed. Traumatic hip dislocationa review. Sports Med Arthrosc. Hak DJ1, Goulet JA. After Perhaps the most common fracture occurs when the head of the femur hits and breaks off the back part of the hip socket during the injury. A direct lateral (Hardinge) approach will allow exposure anteriorly and posteriorly through the same incision. Deutsches rzteblatt International. Hip reduction: To correct your dislocated hip, your healthcare provider will physically move your joint back into place. With the ipsilateral knee close to the physician's chest, the physician maneuvers the hip to 60-90 of flexion and the knee to 90 of flexion. Presentation of posterior hip dislocation. Multiple techniques for reducing a posterior hip dislocation are demonstrated by orthopedic surgeon Dr. Stewart Kerr and emergency physicians Drs. The rehabilitation time may be longer if there are additional fractures. When an artificial hip is dislocated, it may not have suffered the kind of force that would cause secondary injuries. Following successful closed reduction and completion of the stability examination, the patient should undergo CT evaluation. An anterior superior dislocation results when, along with abduction and external rotation, the hip is in extension, and anterior inferior dislocation occurs when the hip is in flexion. Its common in people with hip dysplasia and hip replacement. eds. reduction, although some believe that all fracture-dislocations should The authors prefer to use the Waddell technique for closed reduction of posterior dislocations. Last reviewed by a Cleveland Clinic medical professional on 12/21/2021. For posterior dislocations, internal rotation should be adequate to keep the femoral head from catching on the acetabular cup. When the hip dislocates, the ligaments, labrum, muscles, and other soft tissues holding the bones in place are often damaged, as well. They result from trauma to the flexed knee (e.g., dashboard injury) with the hip in varying degrees of flexion: It typically takes a major force to dislocate the hip. Step-by-Step Description of Hip Dislocation Reduction Give procedural sedation and analgesia (PSA). Copyright 1995-2021 by the American Academy of Orthopaedic Surgeons. With the patient's knee flexed over the physician's leg, the physician applies a gentle downward force on the leg until the hip is reduced (Figure 6).7,42, Captain Morgan Technique: The patient is supine, and the physician stands on the affected side. The socket is formed by the acetabulum, which is part of the large pelvis bone. To learn about pediatric developmental hip dislocation, please read Developmental Dislocation (Dysplasia) of the Hip (DDH). The physician then palpates the protrusion in the gluteal region and pushes the dislocated femoral head until the hip is reduced (Figure 13).7,50, Stimson Gravity Maneuver: The patient is prone, with both hip and knees at 90 of flexion over the edge of the stretcher. Note the metal ring in the polyethylene holding the femoral head inside the acetabulum. Adduction is not recommended during this . Extremity Video: How To Reduce A Hip Dislocation November 29, 2018 TheTraumaPro Leave a comment As a followup to yesterday's hip dislocation post, here is a short 5 minute video that goes through the entire process of reducing hip dislocations. Strong bands of tissue called ligaments provide additional stability to the hip joint. After sustaining a traumatic posterolateral hip dislocation, a seven-year-old boy presented to an outside facility where no attempt was made at reduction. A dislocated hip is acutely painful and disabling and usually follows a significant injury. Forces should focus on the hip joint and avoid the knee to prevent ligamentous injuries of the knee. This can increase the likelihood of future dislocation injuries. The hip can not be moved normally, and the leg on the affected side may appear . A second assistant stabilizes the pelvis while the limb reduces. Dr Neil Duplantier is now affiliated with the Bone & Joint Clinic, Gretna, LA. Severity of injuries associated with traumatic hip dislocation as a result of motor vehicle collisions. With increasing rates of high-energy trauma and numbers of total hip replacements performed, the number of native and postreplacement hip dislocations will likely increase. Study with Quizlet and memorize flashcards containing terms like Posterior Dislocations 1. A subluxation can be mild or severe. This change can lead to a relative retroversion of the acetabulum and to instability of the hip. Here is a quick video on the Whistler technique for hip relocation. Minor trauma tends to be the cause of hip dislocations in young children, whereas greater force is required in adolescents. From the case rID: 10397), Anterior Hip Dislocation (Case courtesy of Dr Sajoscha Sorrentino, Radiopaedia.org. Conclusion: Patients with hip dislocations must receive careful diagnostic workup, and the treating physician must be well versed in the different ways to treat the injury and possible complications. Fracture of the anterior articular surface of the femoral head (black arrow), Fracture of the posterior margin of the acetabulum (green arrow), Fragment of bone (grey arrow) in the soft tissues posterior to the acetabulum, which had arisen from the posterosuperior femoral head, Urgent reduction (<6 hours) should be performed in most cases to reduce the risk of osteonecrosis, If there is an associated hip/femoral neck fracture, the patient may require closed reduction under anesthesia or an open reduction in the OR, Place the patient supine in the bed with the physician either on the bed (as shown) or standing beside the patient, While an assistant stabilizes the pelvis, hold the ipsilateral leg just below the knee, flex it to 90 degrees and apply traction in line with the femur, As the hip begins to reduce, extend the hip and externally rotate to allow the femoral head to slide back into the acetabulum, Place the patient in the supine position with the physician standing beside the bed, Place your forearm beneath the patients knee and grasp the ankle with your opposite hand (as shown), While an assistant stabilizes the pelvis, flex the hip to 90 degrees and apply traction in line with the femur while abducting, externally rotating and extending the hip until reduced, Place the patient in the supine position with both legs flexed and the physician at the standing beside the bed, Slide your arm beneath the knee of the affected side and then hold the knee of the contralateral side, Place your hand on the ankle of the affected leg and apply downward traction at the ankle, internally and externally rotating as needed, Place the patient in a prone position with the legs over the side of the bed in 90 degrees flexion, Place one hand on the patients ipsilateral calf, just below the knee, and the under beneath the ipsilateral ankle (as shown), Apply downward force on the lower extremity using the hand on the calf and use the hand on the ankle to apply internal/external rotation until the hip is reduced, Place the patient in a supine position with the pelvis stabilized by and assistant or strapped to the bed, Stand on the side of the patients bed and place your knee, flexed at 90 degrees, beneath the patients ipsilateral leg, just distal to their knee (as shown), Apply upward traction with the hand behind the patients knee and internally/externally rotate at the ankle until the hip is reduced, Consider in cases of irreducible dislocation, evidence of incarcerated fragments, unstable fracture-dislocation, delayed presentation (>6-12 hrs) or if the reduction is not concentric. PMID: Zahar A et al. Indications for open reduction include hips that have been dislocated for long periods of time, inability to achieve adequate sedation safely in the emergency department, dislocations that are irreducible, fractures of the femoral head or shaft, and persistent instability or redislocation following treatment.9,55 Irreducible posterior hip dislocations can be treated with the Kocher-Langenbeck approach in which the surgeon accesses the posterior structures of the acetabulum by demarcating the posterior superior iliac spine, greater trochanter, and femoral shaft. Allis Maneuver: The patient is in supine position with the physician standing above the patient. Definition: Separation of the femoral head from the acetabulum of the pelvis in either a posterior or anterior direction. If you have a mild subluxation, you might still be able to walk, and you might be able to pop it back into place yourself with gentle stretching. The physician applies a longitudinal force along the femur with the knee extended while the assistant pulls on the cloth to apply lateral traction. At the foot of the bed, the physician creates a fulcrum by placing his/her inner foot against the anterior surface of the ipsilateral ankle and placing the outer foot against the posterolateral hip to feel for the dislocation with the sole. They are much more frequent than anterior hip dislocations. Using hospital sheets knotted to form a loop, an assistant stands in the loop and places the strap through the patient's groin and over the iliac crest. Final reduction is . (B) X-ray shows the dislocated and uncoupled polyethylene head in the patient's soft tissue. Lower leg is flexed, internally rotated and adducted. Physical therapy is often recommended during recovery. Children generally present with groin and thigh pain, flexion and external rotation of the involved hip, and apparent shortening of the lower extremity. (Gardham and Scott 1980; Lev-EI and Rubinstein 1981; Lynn 1921; Meadowcroft and Kain 1977) Gardham and Scott (Gardham and Scott 1980) reported an axillary artery occlusion with an erect dislocation of the shoulder in a 40-year-old patient who . They may order imaging tests, such as X-rays or a CT scan, to better see the position of your bones and screen for any fractures before attempting to correct them. Typically, this requires a large incision, and the surgery may result in a lot of blood loss. This reduction of the femoral head back into the hip socket is typically done under sedation and without surgery, through maneuvers including traction on the thighbone in line with the dislocation. It typically takes a major force to dislocate the hip. A second loop is placed behind the ipsilateral knee, with the physician standing in the loop. Anterior-superior hip dislocation is a rare injury in which ligamentous defects are visualized at MRI and possibly contribute to anterior hip instability and pain. If there are no other injuries, you will receive an anesthetic or a sedative, and an orthopaedic doctor will manipulate the bones back into their proper position. Quality medical care will help you preserve as much of your hip functionality as possible, for as long as possible. Retrieved from http://www.orthobullets.com/recon/5012/tha-dislocation, Hak DJ1, Goulet JA. Pediatric surgical hip dislocation and many more surgical approaches described step by step with text and illustrations. Treatment for joint dislocation is usually by closed reduction, that is, skilled manipulation to return the bones to their normal position. , however, may result from congenital or acquired disorders that cause (1) muscular imbalance, as occurs with congenital hip dislocation or neurologic disorders; (2) . Anterior hip dislocation is commonly reduced by inline traction and external rotation, with an assistant pushing on the femoral head or pulling the femur laterally to assist reduction. The Shenton line should be smooth and continuous.

Hip Joint Dislocation Reduction. Rockwood CA Jr, Green DP, Bucholz RW, Heckman JD, eds. [10] Simultaneously, the assistant leans back to provide lateral traction against the loop, while using the heels of his/her hands to push on the deformity in the gluteal region until the hip is reduced (Figure 15).7,52, Flexion Adduction Method: With the patient supine, the physician stands on the contralateral side and lifts the ipsilateral leg to 90 of flexion and maximum adduction. Although opinions on treatment differ, it is agreed that rapid reduction of hip dislocation is the most important initial treatment [17 . Iliac and pubic dislocations are superior dislocations due to simultaneous abduction, hip extension, and external rotation. Is the mechanism of traumatic posterior dislocation of the hip a brake pedal injury rather than a dashboard injury? The socket is the acetabulum in the pelvis and the ball is the upper "knob" on the thigh bone or femur.. Further, care must be taken to prevent the patient from falling off the stretcher.4,7,51 Because pubic-type dislocations are hyperextension injuries, reduction may not be achieved in such patients because hip flexion is not possible.7,23, If closed reduction fails, open reduction is indicated. Your email address will not be published. Dont mess around with a dislocated hip. Hip Dislocations - Traumatic Key Points: Rare and can be associated with low-energy (younger patient) or high-energy injuries (adolescent patient) Prompt reduction (<6 hours) decreases the risk for avascular necrosis There should be a high level of suspicion for incongruent reduction, with MRI the preferred study to evaluate All Rights Reserved. A hip dislocation is a serious medical emergency. A vessel-preserving surgical hip dislocation through a modified posterior approach: assessment of femoral head vascularity using gadolinium-enhanced MRI, Hip dislocationsepidemiology, treatment, and outcomes, Treatment of hip dislocations and associated injuries: current state of care, The occasional posterior hip dislocation reduction, A detailed review of hip reduction maneuvers: a focus on physician safety and introduction of the Waddell technique, A simple technique for reducing posterior hip dislocation: the foot-fulcrum manoeuvre. J Bone Joint Surg Br. You might need crutches to walk for the first week or two, too. One must evaluate the femoral neck to rule out the presence of a femoral neck fracture before any manipulative reduction. Rotator Cuff and Shoulder Conditioning Program. The physician stands on the affected side, and an assistant stands on the opposite side. After sustaining a traumatic posterolateral hip dislocation, a seven-year-old boy presented to an outside facility where no attempt was made at reduction. (Left)This X-ray, taken from the front, shows a patient with a posterior dislocation of the left hip. Eric F. Reichman. It may be chronic or recurring. Dawson-Amoah K, Raszewski J, Duplantier N, Waddell BS. These injuries are true orthopedic emergencies and should be reduced expediently. Information necessary for a detailed history includes when the patient received the hip replacement, what approach was used, how the dislocation occurred, the number of previous dislocations, and patient compliance with postoperative range of motion restrictions.8 Further, questions about medical conditions (eg, Parkinson disease, multiple sclerosis, alcoholism) and previous surgeries are important because each condition is a potential risk factor that can precipitate dislocations through muscle weakness and imbalance.29 During the physical examination, the physician should assess neurovascular status, as well as the appearance of the affected limb and surgical incision scars that can alert the physician to the approach used. Hip dislocation is usually caused by a traumatic injury. Incredibly painful and affected limb will be immovable. Normally, the femoral heads of both limbs should be equal in size and congruent within the acetabulum.5 On an AP x-ray, a posterior dislocation shows a smaller femoral head in the acetabulum as the bone is positioned further from the x-ray source and closer to the film. Am., 65 (6) (1983), pp. This Guy Suggests Ending Article-Processing Charges to Save Open Access. (, Early identification and reduction is key to prevent complications, Always perform a full trauma and neuro exam, particularly of ipsilateral joints as concomitant injuries are common with traumatic dislocations, Dont be reassured by negative post-reduction XRs as small fractures can occur. The clinical appearance of anterior superior hip dislocation resembles that of a fracture of the femoral neck, whereas the radiological appearance resembles that of posterior hip dislocation. But if you have a replacement hip, it may have dislocated more easily, from something as simple as sitting on a low chair or crossing your legs. We do not capture any email address. Lateral traction is provided as the assistant leans back in line with the femur. The pelvis is fixed and stabilized against the stretcher. A fall from a significant height (such as from a ladder) or an industrial accident can also generate enough force to dislocate a hip. The risk of long-term complications from injured nerves and blood vessels increases if they arent treated within hours. Injury to the ipsilateral knee must be ruled out as well, because the knee is used as the lever in reducing the hip.22, Patients with a posterior dislocation present with a limb adducted, flexed, internally rotated, and shortened. Indications for open reduction of a dislocated hip include: Fracture of the acetabulum or femoral head requiring excision or open reduction and internal fixation. A good practice is to call for cultures, as an unrecognized infection may have caused the instability and dislocation.12,29, Diagnostic imaging of total hip replacement dislocations begins with AP and cross-table lateral x-rays of the hip.8,29 The position of the femoral component and acetabular version and inclination, along with changes in offset and leg length, will help guide the initial management through closed reduction.8 Other important factors include size of the femoral head and type of prosthetic that have been found to play a significant role in the rate of dislocation. When your hip is pushed forward out of its socket (anterior dislocation), your knee and foot will point outward. NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. Hip dislocation is an important orthopedic emergency usually seen in young patients who have experienced high-energy trauma, often resulting in significant long-term morbidity. from the American Academy of Orthopaedic Surgeons, Developmental Dislocation (Dysplasia) of the Hip (DDH). Car accidents and falls from significant heights are common causes and, as a result, other injuries like broken bones often occur with the dislocation. It usually occurs from a significant traumatic injury. The physician places the ipsilateral leg between his/her legs and puts his/her forearm underneath the knee for that limb to flex over the arm. PDF | The anterior hip dislocations are uncommon and are further categorized into pubic or iliac type. Arch Orthop Trauma Surg. Branches from the external iliac artery form a ring around the neck of the femur, with the lateral femoral circumflex artery going anteriorly and the medial femoral circumflex artery going posteriorly.1 The major blood supply to the femoral head is the medial femoral circumflex artery.2-5, Dislocations of the hip can be classified as congenital or acquired. Long-term results in 50 patients, Whistler technique used to reduce traumatic dislocation of the hip in the emergency department setting, Knee injury in patients experiencing a high-energy traumatic ipsilateral hip dislocation, Traumatic anterior dislocation of the hip, Intrapelvic dislocation of the femoral head following anterior dislocation of the hip. The hip is a ball-and-socket joint. On this page: Article: . If the injury is low energy, a complete survey should still be performed to rule out fragility injuries or concomitant injury. To learn about dislocation after total hip replacement, please read Total Hip Replacement. CT scan with 2-3 mm cuts. . PMID: 10421188, Hougaard K, Thomsen PB. reconstruct fractures. Closed reduction may be possible; however, the treating physician should recognize the reason the constraint failed, leading to the dislocation. Black arrows demarcating the bubble sign indicate the polyethylene head. This technique reduces the stress on the treating physician's back by following Occupational Safety and Health Administration principles of keeping the heavy load close to the body and using the feet as a lever to apply inline traction to the patient's leg and hip. Anterior superior hip dislocation accounts for 10% of anterior hip dislocations. PMID: 25597367, Weatherford, B (2011, November). In the case of a prosthetic dislocation, the previous surgical approach should be considered as well as surgeon familiarity and comfort with the approach.2,4,56, As mentioned previously, constrained liners are used in patients with hip instability for various reasons such as recurrent dislocations with properly aligned components and soft tissue laxity. Can be shifted inferiorly (extension > flexion) or superiorly (flexion > extension). Posterior hip dislocations are the most common type, with anterior occurring only about 10% of the time. Nonsurgical reduction by . The ball is the femoral head, which is the upper end of the femur.

Figure 27.5. . PMID: Upadhyay SS et al. But these dislocations are at risk of another time-sensitive outcome muscles contracting away from the implant and no longer holding it in place. We have not included illustrations of the reductions for anterior dislocations because they are performed with the same setup as posterior dislocations.7,24,25,37,54, Allis Leg Extension Method: The patient is supine, and the physician may either climb on the stretcher or stand on the affected side. X-rays illustrate post total hip replacement dislocation (left) and native hip dislocation (right). It causes acute pain and disables your leg until its corrected. This constant traction is superior to the sudden jerks that are inevitable in some of the other reduction techniques. Obturator-type dislocations result from abduction, flexion, and external rotation of the hip.4,7,25 Patients with anterior dislocations may have a palpable femoral head in the femoral triangle in contrast to a palpable femoral head in the gluteal area with posterior dislocations.2, High-energy trauma can cause secondary injuries, so after the history and physical, a provider must complete a neurovascular examination prior to attempting closed reduction. Other common conditions that can lead to postoperative dislocations include laxity or soft-tissue incompetence surrounding the hip joint (ie, revision), incorrect positioning of prosthetic components, and neuromuscular disorders (eg, Parkinson disease).9. (Right)Normal alignment after the hip has been reduced. Hip dislocation occurs when the ball joint of your hip (femur) pops out of its socket (acetubulum). While time to reduction does not play a role in AVN or chondrolysis as the joint has been replaced, minimizing the time to reduction is necessary because of muscular contracture. PMID: Hougaard K, Thomsen PB. Results: Hip dislocations are commonly classified according to the direction of dislocation of the femoral head, either anterior or posterior, and are treated with specific techniques for reduction. Call for help immediately. If youre looking at the injury from the outside, youll first notice that your leg is locked in a fixed position, rotated either inward or outward. The physician applies traction in line with the femur while an assistant stabilizes the pelvis and pushes the head of the femur into the acetabulum until the hip is reduced (Figure 16).7,53, Foot-Fulcrum Maneuver: The patient is supine with the physician sitting at the foot of the bed. Traumatic posterior dislocation of the hip prognostic factors influencing the incidence of avascular necrosis of the femoral head. The physician can apply internal and external rotation to assist in reduction. Injuries about the hip in the adolescent athlete. The hip joint is known as a ball-and-socket joint, in that the ball, or top of each femur, fits into a socket space in the lower portion of the pelvis. Significant knee injuries include effusion (37%), bone bruise (33%), and meniscal tears (30%).19,22,58 Posttraumatic arthritis represents the most common long-term sequela of simple native dislocation, with an incidence rate of approximately 20%.2,3,56,57,59 Sciatic nerve palsy (peroneal component) is the most common neurologic structure damaged as a result of the femoral head stretching the nerve during dislocation or surgical scarring.2-5,26,60 The reported incidence rate of sciatic nerve palsy is 10%-15%.2,3,5,60 Because this injury is also time sensitive, delay in reduction may permanently impair nerve function, and patients may only see partial recovery.2,3,19,26 AVN can occur from prolonged dislocation following trauma or repeated attempts at reduction.2,19 The incidence rate of AVN following hip dislocation is approximately 2%-10%, with increasing rates past 6 hours.2,19,20,57,58 Heterotrophic ossification results in the presence of bone in soft tissue following repeated attempts at closed reduction.2,19 The incidence rate of heterotrophic ossification ranges from 2.8%-9%.3, Adverse sequelae of prosthetic hip dislocations are time-sensitive emergencies but involve less-traumatic inciting events than native dislocations.5,57,58 These complications include damage to the prosthesis, damage to the soft tissue leading to further instability, IPD, fracture of the femur, knee injury, and damage to surrounding neurovascular structures.

Traumatic posterior dislocation of the hip prognostic factors influencing the incidence of avascular necrosis of the femoral head. If reduction is concentric but unstable: Skeletal traction for 4 to 6 weeks is followed by protective weight bearing. The physician can apply internal and external rotation to assist in reduction. However, in a posterior dislocation, the femoral head is usually displaced posterior, superior, and slightly lateral to the acetabulum and also internally rotated . J Trauma.

Is hip dislocation life threatening? 2011 Mar. Time-sensitive treatment is more likely to result in a full recovery. In this case, you will likely not be able to put weight through your leg for 6 to 10 weeks and will be advised to avoid putting your injured leg in certain positions as you heal. The majority will resolve with a closed reduction in the emergency department. hip extension results in a superior (pubic) dislocation Clinically hip appears in extension and external rotation flexion results in inferior (obturator) dislocation Clinically hip appears in flexion, abduction, and external rotation Presentation Symptoms acute pain, inability to bear weight, deformity Physical exam ATLS The physician applies inline traction on the ipsilateral leg, flexing the ipsilateral knee to 90 while an assistant stabilizes the pelvis against the stretcher for countertraction. A. Posterior dislocation is commoner B. Allis has described the most commonly used technique for the reduction of posterior hip dislocation. Most mortality is the result of associated injuries. In dual-mobility implants, two articulation points are at play, with the first point of articulation between a small metal/ceramic femoral head within a larger polyethylene femoral head, and a second point of articulation with the larger polyethylene femoral head and the acetabular component. It creates a low friction surface that helps the bones glide easily across each other. Advertising on our site helps support our mission. Open reduction is a surgical procedure that exposes the fracture site; the fragments are brought into alignment under direct visualization. The limb is placed into 90 of hip flexion, 45 internal rotation, 45 adduction, and 90 of knee flexion. Unrestrained drivers may be at a higher Sometimes, this damage can have long-term consequences, including: A trained healthcare provider can often identify a dislocated hip by looking at it. have immediate open surgery to remove fragments from the joint and to Superior anterior dislocations classically present with the hip extended and externally rotated while inferior anterior dislocations generally present with the hip abducted and externally rotated. 1999 Jul;47(1):60-3. Methods: In this review, the types, causes, and treatment modalities of hip dislocation are discussed and illustrated, with particular emphasis on the assessment, treatment, and complications of dislocations following total hip replacement. Posterior Hip Dislocation (Case courtesy of Dr Hani Salam, Radiopaedia.org. To view chapter written summaries, you need to subscribe. 2 Alabama College of Osteopathic Medicine, Dothan, AL. 1983 Mar;65(2):150-2. Because the anterior ligaments are stronger, trauma to the hip commonly presents as a posterior dislocation when discovered (90% of cases).2,3 Dynamic muscular support includes the rectus femoris, gluteal muscles, and short external rotators.3 An understanding of the vasculature is important because trauma to the hip can displace the femoral head and interrupt the blood supply, leading to avascular necrosis (AVN). Posterior Hip Dislocation Reduction Have an assistant stabilize the pelvis by grasping the bilateral anterior superior iliac spines and applying gentle posterior force. A partial dislocation is known medically as a subluxation. Dislocation of the Hip: A Review of Types, Causes, and Treatment Authors Kwesi Dawson-Amoah 1 , Jesse Raszewski 2 , Neil Duplantier 3 , Bradford Sutton Waddell 3 Affiliations 1 Rutgers Robert Wood Johnson School of Medicine, New Brunswick, NJ. McGraw Hill; 2013. A gentle reduction is then performed, followed by 19 (1): 64-74. These implants are designed so that the polyethylene holds the femoral head in the hip socket by adding a strong constraint around the femoral head; the polyethylene conforms circumferentially around the femoral head, and the polyethylene is stabilized by a circular metal ring on top of the polyethylene. This article addresses hip dislocation that results from a traumatic injury. 2016;8(1):6253. This information is provided as an educational service and is not intended to serve as medical advice. In an open reduction, you are taken to the operating room and placed under anesthesia, and the bones are placed in their normal position using surgery. An analysis of the late effects of traumatic posterior dislocation of the hip without fractures. Car accidents and falls from significant heights are common causes and, as a result, other injuries like broken bones often occur with the dislocation. When there is a hip dislocation, the femoral head is pushed either backward out of the socket, or forward. Reduction of posterior hip dislocations in the lateral position using traction-countertraction: safer for the surgeon? Hip dislocation Taiz University , faculty of medicine and health sciences By Dr : Monther Alkhawlany . Sign up today for full access to all episodes. With hip dislocations, there are often other related injuries, such as fractures in the pelvis and legs; and back, abdominal, knee, and head injuries. Use of 45-degree oblique (Judet) views of, The role of magnetic resonance imaging in, Hip dislocations are classified based on (1) the, Thompson and Epstein Classification of Posterior Hip Dislocations, Epstein Classification of Anterior Hip Dislocations, See Fracture and Dislocation Compendium at, One should reduce the hip on an emergency, Regardless of the direction of the dislocation, the, This consists of traction applied in line with the, The patient is placed prone on the stretcher with the, These have been associated with iatrogenic femoral neck. Superior (iliac or pubic) dislocation is the result of simultaneous abduction, external rotation, and hip extension. Hip arthroscopy and surgical hip dislocation (SHD) can be adequate surgical options for patients suffering from femoroacetabular impingement (FAI) syndrome, but there is to date no published data on their impact on hip muscles strength. If so, there are likely other injuries involved, such as fractures and tears. In a reduction attempt, the femoral head should be manually retracted to the acetabular cup and polyethylene through one of the techniques described previously. Anterior hip dislocations can be treated with the Smith-Petersen or Watson-Jones approach in which the surgeon accesses the anterior structures of the acetabulum by demarcating the anterior superior iliac spine, greater trochanter, and femoral shaft. Current Reviews in Musculoskeletal Medicine. The incision is started a few centimeters proximal to the anterior superior iliac spine (ASIS) and continues along the axis of the femur immediately anterior to the palpable greater trochanter. The risk of necrosis is 3-15% [13,15,16]. Superior (iliac or pubic) dislocation is the result of simultaneous abduction, external rotation, and hip extension. Symptoms of hip dislocation. Epstein classification of anterior hip dislocations. Internal rotation can be applied as needed by leaning from side to side (Figure 17).7,10, Waddell Technique: This technique uses elements of the Allis and Bigelow maneuvers and is modified to protect the physician from back strain during reduction. When this occurs, surgery is required to remove the loose tissues and correctly position the bones. With more abduction, the head is displaced superomedially (pubic) and with less abduction superolaterally (iliac) [7, 8]. The ipsilateral limb is flexed so the hip and knee are at 90. 19 (1): 64-74. A dislocated hip is acutely painful and disabling. Commonest dislocation of the hip is A. Posterior B. Anterior C. Central D. None, 2. (Artificial hip replacements are somewhat easier to dislocate.). The acetabulum is formed from the confluence of the ischium, ilium, and pubis at the triradiate cartilage. A prospective randomised clinical trial comparing FARES method with the Eachempati external rotation method for reduction of acute anterior dislocation of shoulder. however, can be dramatically altered by ipsilateral extremity injuries. Background: Dislocation of the hip is a well-described event that occurs in conjunction with high-energy trauma or postoperatively after total hip replacement. J Bone Joint Surg Br. A dislocated hip joint can damage the nearby nerves, blood vessels and tissues, which may need to be repaired separately. In cases of dislocation, reducing the femoral head through the constrained polyethylene can be difficult. mild Bigelow first described closed treatment of a dislocated hip in 1870, and many reduction techniques have been proposed since then.7 Because closed reduction techniques require placing the patient in different positions (eg, prone, supine, lateral decubitus), the choice of technique should minimize further injury at the time of presentation. There are lots of little tips and tricks. The physician should confirm the position with fluoroscopy and then place a medial force on the lateral aspect of the hip to try to force the femoral head back into the acetabulum. The hip is a stable, well-constrained ball-and-socket joint, requiring 40 to 60 kg (90-135 lb) of axial traction to simply distract and considerably more force to dislocate. A simple, safe and painless method for acute anterior glenohumeral joint dislocations: "the forward elevation maneuver. The authors have no financial or proprietary interest in the subject matter of this article. PMID: Waddell BS et al. The physician places his/her flexed knee under the patient's ipsilateral knee in the popliteal fossa and his/her foot on the stretcher. Conclusion. The time since the primary/revision total hip replacement procedure may inform the physician if the precipitating factor was inadequate soft-tissue healing or prosthetic malposition (early dislocations) or prosthetic wear (late dislocations). Hip dislocation is a marker for a high-force mechanism. Its quick and easy and really doesn't allow you to hurt yourself. Physicians should stand on the side of the bed while performing this maneuver to enhance safety (Figure 5).2,7,41, Lefkowitz Maneuver: The patient is in supine position, and the physician stands to the side of the affected limb. Traumatic hip dislocation in children is relatively rare but presents a true emergency, as a delay in reduction can result in avascular necrosis of the femoral head and long-term morbidity.
