Locked posterior dislocation shoulder is uncommon and frequently missed injury. It account for 2% -4% of all shoulder dislocations. It is commonly associated with osseous defects in humeral head articular surface known as reverse Hill-Sachs lesion. Numerous surgical procedures invented to repair this defect with variable outcomes but evidence based management strategies are lacking. Among these procedures are: transfer of lesser tuberosity or subscapularis tendon, rotational osteotomy of humerus, osteochondral grafts. Salvage procedure as hemiarthroplasty or total shoulder arthroplasty used in huge non-constructable defect or very old neglected dislocation. In our case series, we treated 9 cases (2 females) of locked posterior shoulder dislocation with anteromedial humeral head defects ranging between 30% -50% of head size. Open reduction of dislocation followed by transfer of the lesser tuberosity together with subscapularis tendon for reconstruction of the humeral head defect. The transfer was fixed with Ethibond suture size 5-0 (Ethicon, Inc. Somerville, New Jersy). The mean follow-up period was 14.5 months (range, 12 -25 months). Seven cases had no pain or restriction of activities of daily living. No patient had symptoms of instability of the shoulder. According to UCLA Shoulder rating scale, there were 3 cases rated excellent, 4 cases rated good, one case rated fair and one case rated poor. It is concluded that reconstruction of the humeral head defect provides good pain relief, stability and function for patients with a locked posterior dislocation where the defect involves between 30% -50% of the articular surface circumference. Our technique is simple, cheap and there is no need for second operation for hardware removal.

Aim of study: To demonstrate clinical and radiological effectiveness of intramedullary fixation of closed diaphyseal humeral fractures in adults using the elastic stable intramedullary nail (ESIN). Patients and methods:Between May 2011 and December 2013, twenty-eight patients (19 males) with closed diaphyseal humeral fractures treated with closed reduction and percutaneous fixation with 2 elastic stable nails. Age from 18 to 56 years (mean, 29 years). Patients with open or pathological fractures, those less than 18 years and medically unfit patients were excluded. Causative injury was pedestrian vehicular accident in 15, fall from height 9 and sport-related activity 4 patients. The time of surgical intervention varied from 24 to 72 hours post-injury. Results:Patients were followed up 12-31 months with an average of 20 months. X-ray films showed that twentysix fractures united completely at a range 14-20 week (mean, 13.1 weeks). Twenty-Six cases healed in good alignment at a median time of 13.1 weeks (range 14-20 weeks). One case developed delayed union where bone marrow injection and longer immobilization till full healing done. One case developed non-union which was treated by bone grafting and plating. There were no intraoperative complications. One patient with preoperative radial nerve injury recovered spontaneously by eight weeks. Patients followed and assessed using Disabilities of the Arm, Shoulder and Hand score (DASH). At last follow-up, the average DASH score was 90.5 (range 60-100). Final clinical evaluation showed 17 cases Excellent, 8 cases Good, 2 cases fair and one case Poor according to previous score. Conclusion:Elastic stable nail fixation is a good procedure for treating adult humeral shaft fractures in which stabilization is indicated as it provides stable fixation, with minimal soft tissue stripping at the fracture site and allows early mobilization of the extremity.

Background: Hip resurfacing had been utilized since the 1950s. The concept favored for young active patients owing to its proposed advantages. Revision rate of hip resurfacing in most national registries nearly 3.5%. Conversion to total hip replacement may be the correct option for old patients and those whose activity levels changed and the need for hip resurfacing no longer required.Purpose: The aim of this study is to assess the mid-term outcomes of converting failed hip resurfacing arthroplsty to total hip arthroplasty. Primary outcomes included improvement of Oxford, WOMAC, Harris and UCLA hip scores. Also; radiological follow-up has been evaluated for component stability or signs of loosening. Secondary outcomes included surgical site infection, residual groin pain, and heterotopic ossification. Most of patients (22 patients (88%) reported relief of pain and good to excellent patient satisfaction. Study design: Prospective case series study.Level of evidence: Therapeutic IV.Patients and Methods:Twenty–five patients (fifteen males) with failed hip resurfacing arthroplasty converted to total hip arthroplasty enrolled in this study. Mean age 56.8 years. Mean time to revision 36.8 months. Indications for revision included: femoral neck fractures (10 cases), femoral neck thinning (3 cases), component loosening (4 cases) component dislocation (2 cases) persistent groin pain and clicking (3 cases) and wear of components (3 cases). Nineteen patients revised both components while remaining six underwent revision of femoral component only. Results:The average duration of follow up was 26.8 months (28-48 months). The study was an intermediate term follow-up. Clinical outcome evaluated through Oxford, WOMAC, Harris and UCLA hip scores. Preoperative scores 21.3, 78.3, 35,7 and 2 respectively improved to 39.8, 11.1, 92.3 and 7 respectively at last follow-up representing statistically significant improvements over pre-operative scores (p < 0.0001 for each score) Radiological follow-up evaluated for component stability or signs of loosening. No cases of neurological, vascular, deep infection or implant failure. There were 3 cases (3%) with complications. one case complicated by surgical site infection with serous drainage for more than seven days and treated with oral antibiotics and daily dressings. One case had residual groin pain, and third case had mild heterotopic ossification. All patients were satisfied particularly by their pain relief. Average post operative Oxford, Harris and WOMAC hip scores were 17.4, 89.8 and 6.1 respec-tively. representing statistically significant improvements over pre operative scores (p < 0.0001 for each score)Conclusions: study shows conversion of hip resurfacing to THA has high satisfaction rates. These results compare favorably with those for revision total hip arthroplasty
