Location and size of the reverse Hill-Sachs lesion in patients with traumatic posterior shoulder instability

BackgroundIn patients with traumatic posterior shoulder instability, little is known about the precise location and size of the reverse Hill-Sachs lesion. MethodsForty-nine shoulders of 47 patients with traumatic posterior instability were included in this study based on the following inclusion criteria: 1) a primary or recurrent traumatic posterior shoulder dislocation, and 2) the initial event was caused by trauma. Patients were excluded if they had: 1) no history of trauma, 2) prior shoulder surgery, 3) no CT examination, or 4) seizure cases. Three-dimensional images of the humerus reconstructed from CT images were reviewed using an image analysis software. The location and size of the reverse Hill-Sachs lesion were measured and described on a clock face on the humeral head. ResultsThe reverse Hill-Sachs lesion was observed in 25 of 49 shoulders (51%). The reverse Hill-Sachs lesions were located between 1:37 and 2:48. The depth of the reverse Hill-Sachs lesion (mean ± SD) was 5.8 ± 2.2 mm. The extent of the reverse Hill-Sachs lesion was 35° ± 12°. The average orientation of the reverse Hill-Sachs lesion, represented by an angle measured from the 12 o'clock position, was 64° ± 12° and pointing towards 2:09 on a clock face. Length and width of reverse Hill-Sachs lesions were 9.7 ± 4.7 mm, 11.1 ± 3.6 mm, respectively. ConclusionThe reverse Hill-Sachs lesion was a semicircular compression fracture located on the anteromedial aspect of the humeral head. Compared with shoulders with anterior shoulder instability, the humeral defect was smaller and located more inferiorly in shoulders with posterior instability.

Treatment of Postoperative Instability Following Total Knee Arthroplasty in Patients With Parkinson’s Disease

Acute postoperative posterior total knee arthroplasty (TKA) dislocation is rare in primary surgery but has been associated with Parkinson’s disease (PD). We present a 77-year-old woman with knee arthritis and PD who sustained an acute, recurrent TKA posterior dislocation, recalcitrant to polyethylene upsizing. Transient stability was obtained for a period of 1 year after postoperative hamstring injection with botulinum toxin A and short-term immobilization. Spontaneous instability recurred after 1 year, and stability was obtained with revision to a more constrained construct and has been monitored over a period of 2 years. This is the first report demonstrating the use of botulinum toxin A for acute posterior TKA instability associated with PD. We endorse the necessity of increased constraint to maintain long-term stability in patients with Parkinson’s disease.

Posterior Shoulder Dislocation: About a Case and Literature Review

Posterior glenohumeral dislocation is a rare entity representing less than 3% of all shoulder dislocations. The main etiologies are direct or indirect trauma, seizures and electrocution. Due to clinical signs that are sometimes not very obvious compared to the anterior dislocation and inadequate radiological assessments, the diagnosis is missed in 50 to 80% of cases during the initial presentation. The non-diagnosis of a posterior dislocation most often results in a stiff and painful shoulder settling in chronicity. If the cause is not recognized, which is unfortunately too often the case, many useless rehabilitation and physiotherapy sessions ensue, or even the initiation of alternative medicine with, as a result, the loss of sports and, more seriously, professional activity. Other disabling complications are to be feared, in particular the appearance of glenohumeral instability with episodes of recurrent posterior dislocations, an osteoarthritis model or avascular necrosis of the humeral head. These situations are avoidable if the diagnosis is made from the outset because remedying them, after sometimes-long delays (several months), requires complex surgical reconstruction with a variable success rate. The purpose of this article is therefore to highlight and clarify the challenges and pitfalls presented by posterior shoulder dislocation, its diagnosis and management.

Posterior Reduction and Intra-Articular Cage Fusion With a C2 Nerve Root Preservation Technique for Treating Posterior Atlantoaxial Dislocation Secondary to Os Odontoideum.

Posterior C1-C2 interlaminae compression fusion with iliac bone graft may lead to donor site complications and recurrent C1 posterior dislocation for posterior atlantoaxial dislocation (AAD) secondary to os odontoideum. C1-C2 intra-articular fusion often needs C2 nerve ganglion transection to facilitate exposing and manipulating the facet joint, leading to bleeding from the venous plexus and suboccipital numbness or pain. Therefore, this study was conducted to evaluate the outcomes of posterior C1-C2 intra-articular fusion with a C2 nerve root preservation technique in the treatment of posterior AAD secondary to os odontoideum. Data of the 11 patients who underwent C1-C2 posterior intra-articular fusion because of posterior AAD secondary to os odontoideum were retrospectively reviewed. Posterior reduction was performed using C1 transarch lateral mass screws and C2 pedicle screws. Intra-articular fusion was performed using a polyetheretherketone cage filled with autologous bone from the caudal edge of the C1 posterior arch and cranial edge of the C2 laminar. Outcomes were evaluated by using the Japanese Orthopaedics Association score, Neck Disability Index, and visual analog scale for neck pain. Bone fusion was evaluated by using computed tomography and 3-dimensional reconstruction. The average follow-up duration was 43.9 ± 9.5 months. All patients achieved good reduction and bone fusion, without transection of the C2 nerve roots. The mean bone fusion time was 4.3 ± 1.1 months. There was no complication related to the surgical approach and instrumentation. Function of the spinal cord manifested by the Japanese Orthopaedics Association score significantly improved ( P < .05). The Neck Disability Index score and visual analog scale for neck pain markedly decreased (all P < .05). Posterior reduction and intra-articular cage fusion with a C2 nerve root preservation technique was a promising treatment of posterior AAD secondary to os odontoideum.

Sternoclavicular Joint Reconstruction with Semitendinosus Allograft and Suture Anchors after Recurrent Posterior Dislocation in a Professional North American Football Player

Background: Posterior sternoclavicular joint dislocations are an extremely rare but potentially life-threatening injury that can occur in sports. A variety of surgical procedures have been proposed, but there is no consensus on the treatment of choice. It is also largely unknown if a safe return to high-risk sports is possible. Case Presentation: We present a case of a posterior sternoclavicular joint dislocation in a 22-year-old male professional North American football player who had a recurrent irreducible posterior dislocation after initial injury management by closed reduction. The patient’s desire to return to football presented unique challenges to management. His sternoclavicular joint was subsequently reconstructed with semitendinosus allograft in a figure-of-eight augmented with suture anchors. After recovery, he returned to play as a running back in professional football symptom-free. Conclusion: Our patient's successful return to playing professional football after the sternoclavicular joint reconstruction suggests that this should be considered an effective treatment option when managing posterior sternoclavicular dislocation in high level contact sports players.

Avascular Necrosis of the Femoral Head After Recurrent Traumatic Posterior Hip Dislocation in a 10-Year-Old Girl: A Case Report

Background: Traumatic hip dislocation (THD) is a rare pathology in the pediatric population. The severity of the trauma, mismanagement, or late treatment of such pathology can lead to complications, including avascular necrosis (AVN) of the femoral head. We hereby report a case of recurrent traumatic posterior hip dislocation that eventually lead to AVN of the femoral head in a 10-year-old girl. Case presentation: A 10-year-old girl presented to the Emergency Department complaining of left hip pain one day following a fall from a standing position. On physical examination, the left hip was held in the position of flexion, adduction, and internal rotation, with complete loss of range of motion of the left hip joint. Radiographic imaging was done and showed: a posterior dislocation of the left hip, enlargement of the growth cartilage of the left femoral epiphysis, and hypertransparency of the anterosuperior corner of the left femoral neck, and increased bone density of the upper left femoral epiphysis, suggesting previous hip dislocations. Open reduction with arthrotomy and posterior capsulorrhaphy was performed 36 hours post-injury, followed by hip immobilization by a spica cast. Two months after surgery, the cast was removed. On examination, the left hip was stable with good mobility, and weight-bearing was authorized. Follow-up was done three months post-injury. The patient had no complaints, but radiographic images showed signs of avascular necrosis (AVN) on the left femoral head. Conclusion: Our case emphasizes the importance of early diagnosis and management of a THD in pediatrics, to prevent serious complications such as AVN.

Recurrent posterior elbow dislocation caused by congenital abnormalities in a 7-year-old child

BACKGROUND: Congenital posterior elbow dislocation in children is a rare and scarcely reported condition. Owing to the difficulties of an early primary diagnosis and the lack of a standardized management, we present a clinical case of an analysis of surgical treatment according to literature and based on our experience.&#x0D; CLINICAL CASE: We present a case of congenital posterior elbow dislocation in a 7-year-old child. In the absence of a universal algorithm for surgical treatment, we performed an arthrotomy for visual assessment of articular surfaces, intervention on the capsule and tendons of m. brachialis, m. biceps brachii, m. brachioradialis, and modeling of the proximal epiphysis of the right radius.&#x0D; DISCUSSION: We analyzed surgical treatment options and made an overview of the main stabilizers of the elbow joint that prevent elbow dislocations. There are few publications on this condition; to our knowledge, over the past 10 years, only two clinical cases of a similar pathology in children had been published. Not a single case of congenital elbow dislocation in the neonatal period has been described. We analyzed early clinical manifestations and possible causes of delayed primary diagnosis.&#x0D; CONCLUSIONS: Recurrent posterior elbow dislocation of the congenital origin is associated with a functional deficiency of elbow joint stabilizers. In the neonatal period, these abnormalities are usually not detected. The first episode of dislocation may be triggered by a minor trauma without damaging the bone structures. Delayed primary diagnosis may be associated with the paucity of clinical symptoms and compensatory functionality in children. The decision on surgical correction should be based on the analysis of structural anatomical changes in the assessment, of which magnetic resonance imaging plays an important role.

Recurrent traumatic posterior dislocation of hip in a 5-year-old boy

Recurrent traumatic posterior dislocation of the hip is a rare entity in the paediatric age group. We report an exceptional case of a 5-year old boy who sustained a posterior dislocation of the right hip joint following recurrent trivial trauma while playing, three times in the past one and half year. On literature review, we found that only a few cases have been reported and the management options still remain controversial.

Management of Recurrent Posterior Hip Dislocation in a Down Syndrome Patient with Dysplastic Hip Using Ganz Periacetabular Osteotomy: Follow Up After 4 Years

Recurrent hip dislocation in a Down Syndrome patient with dysplastic hip is a very challenging case to treat even for an expert orthopaedic hip surgeon. Least compliant patient and family, lowly educated with low socioeconomic status and the dysplastic hip forces limited option as a treatment. This is the first case world wide reporting 4 year follow up of dysplastic hip with Down Syndrome treated successfully with PAO technique.Methods:An eighteen years old female with history of Down Syndrome had multiple posterior hip dislocation episodes since 3 years prior. Several attempts of close reduction and hip spica applications were performed upon dislocation despite no successful retaining of reduction. Acetabular index of right hip were 550 and epiphyseal plate hasclosed. PatientwasperformedopenreductionusingSouthern-Mooreposteriorapproachand osteotomy of ischium, continued with capsulorrhaphy followed with Smith-Peterson anterior approach and osteotomy of superior ramus pubis and iliac bone. Then, derotation maneuver was performed under image intensifier to obtain adequate coveragefollowedwithbonegraftandfixationusing2cannulatedscrewandhipspica castapplication.Results:Within four years after surgery, the hip has never been dislocated again, patient could sit without pain and walk with full weight bearing although Harris Hip Score could not be performed due to Down Syndrome. Leg length discrepancy was negligible,fracture has fully united and acetabularin dex was300.Conclusions:Ganz periacetabular osteotomy, although a technically demanding surgery, is a preferable treatment in recurrent hip dislocation for Down Syndrome patient with good to excellent clinical and radiological ou tcome

Abductor Deficiency-Induced Recurrent Instability After Total Hip Arthroplasty.

» Operative intervention for deficient hip abductor muscles may require muscle transfer or the use of synthetic materials, possibly with biologic augmentation, to help stabilize the hip joint and prevent further dislocation following total hip arthroplasty (THA). » Direct repair of the abductor mechanism onto the greater trochanter can be used in patients who present with instability <15 months following primary THA. » Augmentation of soft tissue with acellular dermal allografts can be considered for patients with abductor avulsion that requires posterior capsular reconstruction. » The Achilles tendon + calcaneal bone allograft is indicated for patients who have undergone multiple prior revision surgeries, who have experienced failure of nonoperative management, and have tissue inadequacy in the posterior wall of the hip joint. » The gluteus maximus tendon transfer is indicated in patients with chronic abductor tears, limited or loss of function in the gluteus medius and minimus, and a fully functioning gluteus maximus. » Vastus lateralis transfer may benefit patients with a history of multiple revision procedures, large separation between the gluteus medius tendon and the proximal part of the femur, and the ability to observe the postoperative protocol of splinting for 6 weeks. » The latissimus dorsi tendon transfer should be reserved as a reconstructive procedure for patients with acute abductor insufficiency, such as those who have undergone extensive tumor resection. » Synthetic mesh can be used to enable capsular reconstruction and prosthesis stabilization in patients undergoing salvage procedures for tumors of the hip and associated soft tissues. » Synthetic ligament prostheses can be used in patients with recurrent posterior dislocations in the setting of normal components. » The fascia lata plasty is indicated for patients with recurrent posterior instability without an identifiable cause. » Although the quality of literature is limited, surgical interventions utilizing techniques of soft-tissue augmentation have shown promising outcomes with regard to pain relief, limping, ambulation, and the reduction of instability following THA.

Computer-assisted anteverting eccentric rotational acetabular osteotomy for recurrent posterior dislocation associated with acetabular retroversion: a case report

BackgroundAcetabular retroversion is a rotatory abnormality of the entire hemipelvis that includes anterior over-coverage and posterior deficiency of the acetabulum, and is associated with pincer-type femoroacetabular impingement and posterior hip instability. Acetabular retroversion is thought to cause posterior dislocation of the hip in athletes due to both the pincer-type femoroacetabular impingement and posterior hip instability.Case presentationA 26-year-old Japanese man had acetabular retroversion that induced recurrent posterior dislocation of his hip due to excessive hip flexion while wakeboarding. We performed anteverting eccentric rotational acetabular osteotomy using preoperative three-dimensional planning and an intraoperative computerized navigation system. Our patient was able to return to sports activities 1 year postoperatively.ConclusionsBoth preoperative three-dimensional surgical planning software and an intraoperative navigation system can provide a highly accurate map for this complicated surgery that simultaneously improves the pincer-type femoroacetabular impingement and posterior deficiency of the acetabulum.

Ischiofemoral hip ligament reconstructions for recurrent posterior total hip joint dislocations

ObjectiveRecurrent dislocations of a total hip joint replacement are a difficult problem to address. We present a technique for reconstructing the ischiofemoral ligament of the hip to prevent recurrent posterior dislocations. MethodsThis is a case series of 5 patients with a reconstruction performed using either a bone-patellar tendon-bone graft autograft or allograft. ResultsAt an average follow up of 47 months following the reconstruction, there were no redislocations. ConclusionIschiofemoral hip ligament reconstruction is a viable technique in addressing recurrent dislocations of total hip joint replacements.

Modern Surgical Treatment of Recurrent Posterior Dislocation of the Native Hip.

Redislocation of the native hip is rare. An anterior fulcrum between the proximal part of the femur and the pelvis must be present for a posterior dislocation to occur. The purpose of this study is to describe the cases of 9 patients with posterior redislocation or recurrent subluxation of the native hip that was treated with hip preservation surgery. We retrospectively identified the cases of 9 patients, from 2 institutions, who had undergone hip preservation surgery for the management of posterior redislocation or recurrent subluxation of the native hip after a dislocation. The mean number of dislocations prior to surgery was 3.2 (range, 1 to 7). Pelvic radiographs were used to classify the acetabular morphology, sufficiency of acetabular containment, and structural anatomy of the proximal part of the femur. Radiographic identification of impinging structures was used to guide surgical treatment, which involved either femoral correction alone or the combination of femoral correction and an anteverting periacetabular osteotomy. At a mean follow-up of 73.8 months (range, 10 to 192 months), there had been no subsequent episodes of dislocation or subluxation in any of the hips treated with correction of the anatomic pivot point. An algorithmic approach is presented. In patients who have episodes of redislocation or recurrent subluxation of the native hip, the identification of anatomic abnormalities that create a fulcrum between the proximal part of the femur and the pelvis is critical for making appropriate treatment decisions.

The posterior bundle of the elbow medial collateral ligament: biomechanical study and proposal for a new reconstruction surgical technique.

The medial collateral ligament (MCL) is one of the primary elbows stabilizers. It is composed of an anterior bundle (AB), a posterior bundle (PB) and a transverse bundle. In elbow dislocations, until today MCL reconstruction has addressed the AB only. The purpose of this paper is to understand the biomechanical role of the PB of the MCL and to propose a new surgical technique for the simultaneous reconstruction of the anterior and posterior bundles, preventing the risk of recurrent posterior dislocation or posteromedial rotational instability (PMRI). Sixteen cadaveric elbows were subjected to a force in compression, supination valgus and pronation varus. The residual stability was evaluated in three conditions: intact MCL, sectioned AB and sectioned AB+PB. The tests were performed in collaboration with the Department of Mechanical and Aerospace Engineering of the Politecnico di Torino. In six elbows, the MCL was then reconstructed with the new technique. Complete posterior elbow dislocation does not occur until the PB is sectioned. The section of the AB alone causes elbow instability in valgus stress, but not a dislocation. The reconstruction of the AB and the PB using the described technique allows a good recovery of range of motion and joint stability. The PB of the MCL has a primary role in elbow stability against valgus stress, and it prevents elbow posterior dislocation at all flexion angles. The described reconstruction technique should reduce the risk of residual PMRI.

Late Anterior Dislocation Due to Posterior Pelvic Tilt in Total Hip Arthroplasty.

Background:Excessive pelvic tilt may be one of the factors leading to instability in total hip arthroplasty (THA), even when the acetabular cup is placed properly. To our knowledge, only a few studies have described late anterior dislocation due to posterior pelvic tilt. We present 3 cases with late anterior dislocations possibly due to posterior pelvic tilt.Cases Presentations:Case-1: An 84-years-old woman fell and presented with an anterior dislocation 12-years after THA. Her pelvis had tilted to approximately 30° posteriorly in a supine position. After conservative treatment, she presented with 10 recurrent anterior dislocations. She had thoracolumbar kyphosis due to multiple compression fractures. Revision with anterior placement of an elevated liner and a 32-mm head corrected the dislocation, and no further dislocations occurred.Case-2: A 78-years-old woman fell and presented with an anterior dislocation 4-years after THA. Her posterior pelvic tilt had increased 23° due to a lumbar compression fracture. Revision by decreasing the cup anteversion was performed, but recurrent posterior dislocations occurred. Owing to her worsened general condition, further treatment was abandoned.Case-3: A 79-years-old woman twisted her body and presented an anterior dislocation 3-years after THA. After manual reduction and conservative treatment, the dislocation recurred. Her posterior pelvic tilt had increased 16°.Conclusion:Although minor trauma triggered the anterior instability in these patients, the underlying pathomechanism existed in the progressive pelvic posterior tilt due to thoracolumbar kyphosis. As longer life expectancy as well as implant survivorship is predicted, attention must be paid to the change of pelvic tilt in elderly patients.

Posterior bone block: a reliable method to treat recurrent nonlocked posterior shoulder dislocation with engaging reverse Hill–Sachs lesion

Background Posterior shoulder dislocation was first reported in 1839 by Sir Astley Cooper. Hill and Sachs, in 1940, stated that with any dislocation event the soft bone of the humeral head impacts against the harder, sharper edge of the glenoid, leading to an impression fracture of the posterosuperior head in recurrent anterior dislocation. A reverse Hill–Sachs lesion is an impression fracture in the anterosuperior head in recurrent posterior dislocation. In 1952, McLaughlin described his surgical technique to treat an anterior impression fracture of the humerus after recurrent posterior shoulder dislocation. Hypothesis Our hypothesis is to prove that posterior bone block augmentation of the posterior glenoid is a safe and reliable line of treatment in cases of recurrent posterior instability with engaging reverse Hill–Sachs lesion. Patients and methods Between March 2009 and March 2011 five cases were referred to us with chronic recurrent posterior shoulder dislocation with engaging reverse Hill–Sachs lesion. The mean age of the patients was 28 years (range: 20–36 years). There were two left and three right shoulders. All patients were male. All patients were manual workers. All sustained traumatic dislocations through nonathletic accidents. None of the patients had epileptic fits before. Preoperatively, the mean active forward elevation was 140° (range: 130°–150°) and external rotation with the arm at the side was 35° (range: 20°–50°). Preoperative constant score average was 40 points (range: 30–50 points). The mean time interval between injury and surgery was 12 months (range: 8–16 months). All cases had engaging reverse Hill–Sachs lesion. None of the cases had significant posterior glenoid bone loss. All patients were treated with open posterior bone block augmentation of the posterior glenoid harvested from the anterior iliac crest. Results Patients were evaluated at 3, 6, 12, and 24 months. Range of motion was recorded and follow-up radiographs were taken to evaluate graft incorporation. The mean follow-up time for the five patients was 30 months (range: 24–36 months). At 6 months postoperatively, the mean forward elevation was 165° (range: 160°–170°) and external rotation with the arm at the side was 55° (range: 40°–70°). Patients were evaluated postoperatively according to the constant score system (maximum: 100 points). We found a mean postoperative constant score of 87.5 points (range: 80–95 points), a fairly good result considering the nature of bone loss. Conclusion The posterior bone block can successfully restore the stability and function of the shoulder in patients with recurrent posterior dislocations with significant engaging reverse Hill–Sachs lesion in which arthroscopic soft-tissue reconstruction is not a reasonable option. This technique can be used for combined soft tissue and bony defects as well as for revisions after previous soft-tissue reconstructions.

Recurrent Posterior Dislocation of the Elbow

The elbow joint is one of the most inherently stable articulations of the skeleton. Recurrent posterior dislocation of the elbow is a rare condition. We experienced a case of recurrent posterior dislocation of the elbow due to shallow trochlear notch and chronic radial head dislocation that was treated by transplantation of the biceps tendon to the coronoid process. We report on the case with a literature review.

Results of an open posterior bone block procedure for recurrent posterior shoulder instability after a short- and long-time follow-up.

The aim of the present study was to analyse and compare the clinical and radiological results after open posterior bone block procedure at long- (LT) and short-term (ST) follow-up. The hypothesis was that placement of a bone block at the posterior glenoid rim in a technique of extending the glenoid surface will create permanent joint stability even in cases with hyperlaxity without a clinically relevant loss of motion or increase in osteoarthritis. Fifteen consecutive shoulders with recurrent posterior dislocation were evaluated clinically and radiologically. The Rowe score, Western Ontario Shoulder Index, Walch-Duplay score and the Constant-Murley score were used for clinical evaluation. The patients were categorized according to their follow-up period as either ST follow-up (min 12 months) or LT follow-up (min 42 months). The clinical results showed no significant difference between ST (9) and LT (6) with good to very good overall results in the subjective as well as the objective scores (CS, RS, WDS). At LT, most patients felt mild to minor pain under strain. The difference in pain between the groups was not significant. Active ranges of motion and strength assessments were normal in all cases. In one case, recurrent dislocations occurred after bone graft resorption 6 months post-operatively. Only one patient presented mild osteoarthritis, without further progress at follow-up. The open posterior bone block procedure can be a successful treatment option for recurrent posterior shoulder instability at ST and LT follow-up. This series showed a low rate of recurrent dislocations without development or progression of osteoarthritis. Since soft tissue procedures do not always provide satisfying results, the posterior bone block augmentation presents a reliable technique for the treatment of symptomatic posterior instability.

Acetabular Wall Augmentation in Selected Patients With Recurrent Dislocation After THA

We reviewed 42 patients operated with PMMA augmentation of the acetabular wall for recurrent posterior dislocation of cemented total hip arthroplasties with a cemented all-poly acetabular component. 38 patients never experienced subsequent dislocations after the procedure. 4 patients had recurrent dislocations, and two additional patients underwent a revision procedure due to aseptic loosening of the acetabular component. 1, 5 and 10years survival of the prosthesis free of dislocation were 95%, 95% and 64% respectively. 90% of the patients were satisfied, four patients experienced pain and 3 patients sustained an infection. The procedure is simple, effective, takes less time and results in less blood loss compared to full revision surgery. It should be considered in cases of recurrent posterior dislocation in elderly patients.
