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. A superiorly dislocated hip post trauma Dislocation after hip replacement surgery has the highest incidence rate immediately after the surgery or in the first three months. (A) Dual-mobility implant components include a small central metal or ceramic head joined to a larger polyethylene head within an acetabular cup. Thank you for your interest in spreading the word on Ochsner Journal. The physician grasps the ipsilateral ankle with one hand and places the free hand under the ipsilateral knee, applying an upward force by plantar flexing the foot until the hip is reduced. Sometimes, this damage can have long-term consequences, including: A trained healthcare provider can often identify a dislocated hip by looking at it. Usually, the femoral head will perch on the constrained rim. 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. As the limb reduces, internal rotation can be used if needed (Figure 10).7,46, Piggyback Method: The patient is supine at the edge of the stretcher, and the ipsilateral hip is flexed to 90. Anterior hip dislocations are classified as either superior-anterior (pubic) or inferior-anterior (obturator).7,23,24 Pubic-type dislocations result from abduction, extension, and external rotation of the hip. Capehart, BA, et al. 760-767. With an assistant stabilizing the patient's pelvis, the physician grasps the ipsilateral knee and applies inline traction until the hip is reduced. The physician places his/her arm under the ipsilateral knee so the leg is flexed over the forearm and uses the same hand to grasp the contralateral knee. These comprise 10% to 15% of traumatic hip dislocations. We do not endorse non-Cleveland Clinic products or services. A hip dislocation is a serious medical emergency. A hip dislocation can have long-term consequences, particularly if there are associated fractures. 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 . It takes a lot of force to dislocate a hip joint, and a lot of force to put it back. Web. Dislocation after total hip arthroplasty. 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. Which is true about dislocation of hip joint? Time-sensitive treatment is more likely to result in a full recovery. AAOS does not endorse any treatments, procedures, products, or physicians referenced herein. Step-by-Step Description of Hip Dislocation Reduction Give procedural sedation and analgesia (PSA). The reduction of dislocation is a procedure to manipulate the bones back to their normal position. PMID: Waddell BS et al. In almost all cases, the dislocation can be confirmed with an anteroposterior (AP) x-ray of the hip, but if the finding is vague, additional x-rays (frog-leg lateral, cross-table lateral, Judet views) can be taken as needed.2,5 Not only does an AP view confirm the cause and type of dislocation but can also show signs of lumbar injury and acetabular fractures. Posterior Hip Dislocation Reduction Have an assistant stabilize the pelvis by grasping the bilateral anterior superior iliac spines and applying gentle posterior force. 1999 Jul;47(1):60-3. Sign up today for full access to all episodes. however, can be dramatically altered by ipsilateral extremity injuries. from the American Academy of Orthopaedic Surgeons, Developmental Dislocation (Dysplasia) of the Hip (DDH). 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. We however found that flexion at the hip was practically not possible and that lateral pulling on the thigh could be helpful in dislodging the femoral head. 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. PMID: 27114811. Get useful, helpful and relevant health + wellness information. Closed reduction is carried out as soon as possible after diagnosis to avoid neurologic injury [20]. If youve had a replacement hip, your healthcare provider might recommend a brace to stabilize it while it heals. 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. (, 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. J Bone Joint Surg Br. Traumatic posterior dislocation of the hip prognostic factors influencing the incidence of avascular necrosis of the femoral head. Adduction is not recommended during this . The mechanism often involves an axial load through a femur that is internally rotated, flexed, and adducted at the hip. Copyright 1995-2021 by the American Academy of Orthopaedic Surgeons. 1983 Mar;65(2):150-2. Rotator Cuff and Shoulder Conditioning Program. Symptoms of hip dislocation. Posterior hip dislocations are the most common type, with anterior occurring only about 10% of the time. A subluxation can be mild or severe. All Rights Reserved. When hip dislocation is the only injury, an orthopaedic surgeon can often diagnose it simply by looking at the position of the leg. 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. We do not capture any email address. The physician places the patient's knee on his/her shoulders and using the shoulder as a fulcrum, applies a downward force on the tibia to create an anteriorly directed force at the hip until it is reduced (Figure 11).7,47, Tulsa Technique/Rochester Method/Whistler Technique: The patient is supine, and the physician stands on the affected side, placing the contralateral knee in 130 of flexion. 2010;68(2):91-6. Etiology Acquired Accept The pelvis is fixed and stabilized against the stretcher. Severity of injuries associated with traumatic hip dislocation as a result of motor vehicle collisions. . I call it the under-over technique: I put my arm UNDER the knee of the affected side and rest my hand OVER the good knee. The Tulsa technique, Closed reduction of posterior hip dislocation: the Rochester method, Posterior hip dislocation, a new technique for reduction, A Practical Treatise on Fractures and Dislocations. This is called a posterior wall acetabular fracture-dislocation. They result from trauma to the flexed knee (e.g., dashboard injury) with the hip in varying degrees of flexion: If the hip is in slight abduction, an associated fracture of the posterior-superior rim of the acetabulum usually occurs. 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. 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. With the free hand, the physician fixes the ipsilateral ankle against the stretcher and applies downward traction using the ankle along with internal and external rotation until the hip is reduced (Figure 12).7,21,46,48,49, Skoff Maneuver: The patient is in the lateral decubitus position with the ipsilateral limb facing up. open PMID: 3566493, Upadhyay SS et al. Minor trauma tends to be the cause of hip dislocations in young children, whereas greater force is required in adolescents. The physician applies longitudinal force along the femur while the assistant pulls on the cloth to apply lateral traction as the hip is reduced. Superior (iliac or pubic) dislocation is the result of simultaneous abduction, external rotation, and hip extension. Sports Med Arthrosc. A dislocation of the hip is a relatively uncommon event typically caused by high-energy trauma. Patients may require a blood transfusion during or after this surgery. Most mortality is the result of associated injuries. Severity of injuries associated with traumatic hip dislocation as a result of motor vehicle collisions. A dislocated hip is acutely painful and disabling. 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. It causes acute pain and disables your leg until its corrected. (, Dislocation one of the most common complications after arthroplasty, occurring due to laxity, implant positioning, improper implant choice and impingement. When an artificial hip is dislocated, it may not have suffered the kind of force that would cause secondary injuries. 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. 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. 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. To learn about pediatric developmental hip dislocation, please read Developmental Dislocation (Dysplasia) of the Hip (DDH). The physician uses his or her hands to push the inferior tip of the scapula medially while moving the . It usually occurs from a significant traumatic injury. From the case rID: 10397), Anterior Hip Dislocation (Case courtesy of Dr Sajoscha Sorrentino, Radiopaedia.org. A dislocated hip is acutely painful and disabling and usually follows a significant injury. PMID: 21293240, Zahar A et al. Wearing a seatbelt can greatly reduce your risk of hip dislocation during a collision. However, if youve had a minor injury, or if your hip has suffered a lot of wear and tear, you may have a subluxation. 963 Other multiple significant trauma with mcc. With the physician stabilizing the pelvis with a free hand, a second assistant applies a downward force while the physician and first assistant apply an inline upward force with extension of their knees. A smooth tissue called articular cartilage covers the surface of the ball and the socket. Open reduction of the hip and internal fixation of the fracture was carried out using a twin incision . 2016;8(1):6253. Although mastery of each technique is not mandatory, becoming proficient in a few techniques will aide in the flexibility of treatment when one approach fails to work.2,7 Posterior and anterior methods of reduction are described and illustrated below. 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. 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. Your rotated leg may also appear shorter or longer than the other. 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. Forces should focus on the hip joint and avoid the knee to prevent ligamentous injuries of the knee. Hip dislocations are time-sensitive medical emergencies that must be treated promptly to prevent permanent complications.19,20 Because of the traumatic nature of native hip injuries, taking the first steps in advanced trauma life support is critical to stabilize the injured patient. Dislocation following total hip replacement, Prevalence of total hip and knee replacement in the United States, Dual mobility cups in total hip arthroplasty, U.S. Department of Transportation National Highway Traffic Safety Administration, Traffic safety facts: research note. 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 With an assistant stabilizing the patient's pelvis against the stretcher, the physician climbs on the stretcher. The labrum forms a gasket around the socket, creating a tight seal and helping to provide stability to the joint. Hold on to the rail when using stairs, and take it slowly when bending at your waist. (B) X-ray shows the dislocated and uncoupled polyethylene head in the patient's soft tissue. 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. Limb is short, internally rotated and adducted. attempted. Multiple techniques for reducing a posterior hip dislocation are demonstrated by orthopedic surgeon Dr. Stewart Kerr and emergency physicians Drs. Unless reducing obturator-type dislocations, hip flexion is not possible as the femoral head rests on the anterior surface of the pelvis. The appearance and alignment of the extremity, When this occurs, surgery is required to remove the loose tissues and correctly position the bones. CT scan with 2-3 mm cuts. Car accidents and falls from significant heights are common causes and, as a result, other injuries like broken bones often occur with the dislocation. Timely evaluation and treatment, including recognizing the potential complications, are necessary to offer the best outcome for the patient. If suspicion for associated fracture, subsequent CT is recommended to fully characterize the injury . 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. 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 A hip dislocation is very painful. Allis has described the most commonly used technique for the reduction of posterior hip dislocation. It normally takes a lot of force to push your hip joint out of its socket. Quality medical care will help you preserve as much of your hip functionality as possible, for as long as possible. 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. Repeat hip dislocation during this passive ROM exercise is diagnostic of clinical joint instability.. PRINCIPLES OF MANAGEMENT Mechanism of Injury The vast majority of hip dislocations occur from high-energy motor vehicle trauma. A prospective randomised clinical trial comparing FARES method with the Eachempati external rotation method for reduction of acute anterior dislocation of shoulder. In the case of an ipsilateral displaced or nondisplaced femoral neck fracture, closed reduction of the hip should not be, Management after closed or open reduction. 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. reduction, although some believe that all fracture-dislocations should Patients with native and postoperative total hip replacement 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. 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. Hip dysplasia is also called developmental dislocation of the hip (DDH). Nonsurgical reduction by . Advertising on our site helps support our mission. The physician provides lateral traction in line with the femur by leaning back while using his/her free hands to manipulate the lower limb. Occurs with axial loading of hip in extension and abduction or from a significant posterior force on the joint forcing the femoral head anteriorly. Emergency Medicine Procedures, 2e. 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. 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. This procedure is described in a 2012 case report that examined the successful post closed reduction outcome of a dual-mobility implant in an older individual with risk factors for dislocation.33, Dual-mobility implants were introduced in the United States in 2009.36 As noted previously, these implants have a small and a large articulation that can dissociate during dislocation or a reduction attempt. A superior dislocation is rare . McGraw Hill; 2013. If this is performed externally, i.e., without opening the hip, it is known as a closed reduction. We report a case of superior dislocation of the hip with anterior column acetabular fracture. Final reduction is . The physician can apply internal and external rotation to assist in reduction. Your doctor will order imaging tests, such as X-rays and likely a CT scan, to show the exact position of the dislocated bones, as well as any additional fractures in the hip or femur. 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. With hip dislocations, there are often other related injuries, such as fractures in the pelvis and legs; and back, abdominal, knee, and head injuries. 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. 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. All rights reserved. Most authors recommend an immediate attempt at a closed Your dislocated hip was most likely caused by a traumatic injury. 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. Keywords. 2011 Mar. Bigelow first described closed treatment of a dislocated hip in 1870, and since then many reduction techniques have been proposed. Traction is applied in line with the deformity, and the hip is adducted, internally rotated, and extended.4,7 If climbing on the stretcher is not necessary, standing on the side of the stretcher is preferred for physician safety.7,41, Lateral Traction Method: The patient is supine, and the assistant wraps a cloth around the ipsilateral inner thigh. The outcome following hip dislocation ranges from an essentially normal hip to a severely painful and degenerated joint. 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. An anteroposterior (AP) radiograph of the pelvis is essential, as well as a cross-table lateral view of the affected hip. But these dislocations are at risk of another time-sensitive outcome muscles contracting away from the implant and no longer holding it in place. Itll also cause arthritis in your joint to develop over time in about 50% of cases. This change can lead to a relative retroversion of the acetabulum and to instability of the hip. Hak DJ1, Goulet JA. Is the mechanism of traumatic posterior dislocation of the hip a brake pedal injury rather than a dashboard injury? For pubic-type dislocations, hyperextension of the hip is required for reduction.7,24,40,54, Reverse Bigelow Method: The patient is supine, and the physician grasps the ipsilateral limb at the ankle with one hand and places the free hand behind the knee. Arch Orthop Trauma Surg. Types of anterior dislocation Pubic (superior) Obturator (inferior) Perineal 25. . Hip dislocation is a marker for a high-force mechanism. (, 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.

Posterior Hip Dislocation (Case courtesy of Dr Hani Salam, Radiopaedia.org. Tulsa technique/Rochester method/Whistler technique. The Allis reduction technique for posterior hip dislocations. Posterior hip dislocations are the most common type and are reduced by placing longitudinal traction with internal rotation on the hip. . If only 2 people are available, this technique can still be completed. Hip reduction: To correct your dislocated hip, your healthcare provider will physically move your joint back into place. J Trauma. Motor vehicle collisions are the most common cause of traumatic hip dislocations. Acquired hip dislocations are either native dislocations or dislocations after total hip replacement (Figure 1).3,7-10 The majority of native hip dislocations result from motor vehicle collisions.4 In the typical scenario, the patient is sitting with the hip in flexion, and upon impact, the thigh hits the dashboard, sending a posteriorly directed force to the joint and causing a posterior dislocation.4,11 The most common acquired dislocation is hip dislocation that occurs within the first 3 months following total hip replacement.12 This scenario occurs when the patient reaches the extremes of the prosthetic range of motion and the femoral neck levers on the acetabular cup, allowing the femoral head to escape from the acetabulum. Health providers must be familiar with best practices to diagnose and treat these patients. This Guy Suggests Ending Article-Processing Charges to Save Open Access. You should always consider CT. Sanders S et al. In: Reichman EF. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. They result from external rotation and abduction of the hip. The challenge with these prostheses is that in restricting motion, they tend to fail catastrophically, and dislocations can necessitate open reduction or revision. Finally, centricity of the femoral head should be confirmed in the postreduction x-rays. If a second assistant is not available, the first assistant stabilizes the pelvis as the physician holds the ipsilateral lower leg by the knee. Early treatment is necessary as instability will occur with the improper articulation of the small metal/ceramic femoral head on the much larger acetabular cup, and the metal/ceramic femoral head will damage the acetabular cup, necessitating its revision.35, A newly recognized phenomenon in patients who have had a hip replacement and then undergo lumbar fusion surgery is dislocation that occurs because of the change in sacral slope and pelvic tilt. 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. When an individual receives a hip dislocation, there is an incidence rate of 95% that they will receive an injury to another part of their body as well. superior (pubic/iliac) hip dislocation (rare) central hip dislocation - always associated with acetabular fracture 2,3 Hip dislocation can be further classified as being simple (pure without associated fracture) or complex (dislocation associated fracture of the acetabulum or proximal femur) 6 . Closed reduction techniques for anterior dislocations require a slight variation in maneuvers, but treatment requires the same inline traction on the femur, hip extension, and external rotation. A milder case may be caused by general wear and tear on your hip, when the cartilage that helps seal your joint in its socket has eroded. The most common symptoms of a hip dislocation are hip pain and difficulty bearing weight on the affected leg. Deutsches rzteblatt International. This technique requires 2 people. Allis Maneuver: The patient is in supine position with the physician standing above the patient. 19 (1): 64-74. Injuries about the hip in the adolescent athlete. In cases of hip dislocation with other associated injuries, such as fractures of the femur or pelvis bone or injuries to the nerves or blood vessels, the doctor may recommend an open reduction. To reduce the risk of slamming the femoral head against the superior rim of the acetabulum during reduction, the physician gently maneuvers the affected limb to maximum allowed flexion to move the dislocated femoral head into a more posterior position. Its occurrence with acetabular fractures has been documented infrequently. The implant may need to be replaced again, or reinforced. Its common in people with hip dysplasia and hip replacement. have immediate open surgery to remove fragments from the joint and to Unrestrained drivers may be at a higher Sports Med Arthrosc. PMID: Zahar A et al. Dislocated Artificial Hip Reduction 319,085 views Nov 4, 2012 1.8K Dislike Share Save Larry Mellick 581K subscribers The reduction technique for a dislocated hip is demonstrated in this. While far less common, hip dislocations can result from a collision while playing a sport, like football or hockey. When the small femoral head reaches the limit of its range of motion, the larger femoral head will then move which allows for an increased range of motion before impingement (Figure 3A).14,35,36 However, because of the additional bearing compared to fixed-bearing total hip replacement, a unique dislocation can occur known as an intraprosthetic dislocation (IPD) (Figure 3B).14,35 In an IPD, the larger polyethylene femoral head dissociates from the smaller femoral head.35,36 Postreduction x-rays can show what appears to be a successful reduction; however, in an IPD, the femoral head is eccentrically located in the acetabulum, and close evaluation reveals a halo in the soft tissue, representing the polyethylene that has dissociated (Figure 3B). Am., 65 (6) (1983), pp. The diagnosis of congenital hip-joint dislocation by the ultrasonic Compound treatment, Archives of orthopaedic and traumatic surgery . On this page: Article: . Timely evaluation and treatment, including recognizing the potential complications, are necessary to offer the best outcome for the patient. The assistant grasps the thigh and applies a lateral traction force. Cleveland Clinic is a non-profit academic medical center. Posttraumatic osteoarthritis: This is the, Thromboembolism: This may occur after hip. Further caution must be taken to prevent the patient from falling off the stretcher (Figure 14).4,7,51, Traction-Countertraction Maneuver: This technique is a modification of the Skoff lateral reduction maneuver and requires 2 people. In this case, 40 years old male patient met with a car accident and was brought to the emergency room with the complaint of severe pain in his left hip joint and inability to move his left lower limb. 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. Inferior dislocation of the hip is a rare clinical entity, wherein closed reduction maneuver could be challenging, especially if the attending surgeon is not familiar with the specific anatomy associated with this injury. Predisposing factors for hip dislocations continue to rise.2,10,13,14 A 2014 report by the National Highway Traffic Safety Administration noted more than 2.3 million motor vehiclerelated injuries occurred among predominantly younger drivers, an increase of 1.1% since 2013.15 A summative 1982 study by Woo and Morrey found a dislocation rate of 3.2% in more than 10,000 primary total hip replacement procedures.16 Other studies have reported dislocation rates as high as 10% for primary procedures and up to 28% for revision.10,12,17,18 By 2030, the number of procedures is projected to increase 174% for primary hip replacements and 137% for revisions, suggesting that the number of patients who present with dislocations may also increase.13,17 The assessment, treatment, and complications of dislocations following total hip replacement are the primary emphasis of this review. After sustaining a traumatic posterolateral hip dislocation, a seven-year-old boy presented to an outside facility where no attempt was made at reduction. J. Treatment for joint dislocation is usually by closed reduction, that is, skilled manipulation to return the bones to their normal position. 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. They result from trauma to the flexed knee (e.g., dashboard injury) with the hip in varying degrees of flexion: The physician applies inline traction with internal and external rotation until the hip is reduced (Figure 9).7,45, Lateral Traction Method: With the patient supine, the assistant wraps a cloth or his/her hands around the patient's ipsilateral inner thigh. Posterior Hip Dislocation Mechanism of injuryfemoral head is forced out of the acetabulum and rests posteriorly Clinical featuresaffected extremity shortened, adducted, and internally rotated; patient may hold hip flexed with knee of affected extremity resting on opposite knee (FIGURE 66.1) Radiographic evidencefemoral head resting posterior to the acetabulum (FIGURE 66.2) 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. Anterior dislocation of hip joint is a rare injury accounting for 11-15% of all hip dislocations [1]. PMID: 25597367, Weatherford, B (2011, November). Hip dislocation can cause long-term damage, especially if its not treated right away. of anterior dislocation (70% of all anterior dislocations) [3]. reconstruct fractures. The patient lies supine and the operator holds the knee flexed at 90 degrees. We however found that flexion at the hip was practically not possible and that lateral pulling on the thigh could be helpful in dislodging the femoral head. You may recover well in the short term, but the injury may come back to haunt you later in life. No more than 6 hours should elapse between presentation and reduction. The assistant stabilizes the pelvis while helping the physician apply inline traction to the ipsilateral limb by extending the legs until the hip is reduced (Figure 8).7,44, Howard Maneuver: The patient is supine, and both physician and assistant stand on the affected side. If reduction is concentric and stable: A short period of bed rest is followed by protected weight bearing for 4 to 6 weeks. 2010;68(2):91-6. Don't hesitate to seek emergency care if you suspect a dislocated hip. The physician uses the arm closest to the patient's ipsilateral hip as the pivot and the other arm to grab the ipsilateral leg. It typically takes a major force to dislocate the hip. Recognizing these concomitant injuries early is important because they may be exacerbated by closed reduction. PMID: 20632983, Kovacevix D et al. If reduction is concentric but unstable: Skeletal traction for 4 to 6 weeks is followed by protective weight bearing. Patients presenting with dislocations of the hip typically are unable to move the lower extremity and are in severe discomfort. X-ray shows the constrained liner in total hip replacement. The majority will resolve with a closed reduction in the emergency department.

Posterior Dislocations They are much more frequent than anterior hip dislocations. The reduction of superior hip dislocation proceeds with strong traction in line of limb axis and gradual internal rotation and flexion of the hip. Figure 27.6. Surgical dislocation of the hip provides significant advantages over traditional approaches, including complete visualization of the femoral head for fracture reduction and fixation, access to the joint for debridement, and access to the acetabulum for fixation of associated injuries. If so, there are likely other injuries involved, such as fractures and tears. But theyll also want to perform a full physical evaluation to check for other related injuries. 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. Following successful reduction of a prosthetic hip, a balance between immobilization and guarded mobilization must be achieved.4 Knee immobilizers or hip-abduction braces can be used to prevent patients from breaking the precautions associated with their surgical approach.8,62 In posterior dislocations, the brace should restrict flexion of the limb to 90 and avoid internal rotation and adduction. A. Posterior dislocation is commoner B. It creates a low friction surface that helps the bones glide easily across each other. Epidemiology Incidence 1-3% 70% occur within first month 75-90% posterior Etiology Mechanism anterior extension and external rotation of hip posterior For hip posterior fracture-dislocation, the current consensus is to perform joint reduction as soon as possible. 1986;106:32-35. Posterior hip dislocations are the most common type and are reduced by placing longitudinal traction with internal rotation on the hip.
