Bridge plating with decortication, autologous bone graft, and tight closure: a "stepwise surgical diamond concept" for treatment of nonunion in a series of fifty five patients.

PURPOSE: This study was conducted to assess a stepwise surgical procedure applied to treat a continuous series of patients with aseptic atrophic nonunion of long bones. METHODS: A retrospective review was performed of the medical files of patients treated by the senior author between January 2014 and January 2021 for aseptic atrophic nonunion of long bones using a standard stepwise surgical procedure consisting of four successive surgical steps: bridge locked plating, aggressive osteoperiosteal decortication, copious autologous iliac bone grafting, and tight closure without drainage. Patients were clinically and radiographically evaluated until bone healing, then at final follow-up for the purpose of the study. The primary objective of the study was to assess completion of bone healing; secondary objectives were the time required reaching bone union, the occurrence of complications at the iliac bone graft donor site, and the achievement of bone consolidation after a second attempt of treatment when indicated following failure of the index procedure. RESULTS: There were a total of 55 patients. One patient died from myocardial infarction before reaching bone healing and another one lost from early follow-up. There were remaining 53 patients with 37 years of mean age. The affected bone was the clavicle in five patients, humerus in 14, ulna in four, radius in one, femur in 13, and tibia in 16. The mean follow-up period was 3.4 years. A total of 52 patients (98.1%) achieved bone healing at a mean of 14.8 weeks from the index procedure. The only patient who did not reach bone healing after the index procedure was successfully revised using decortication-bone graft and new fixation with intra-medullary femoral nailing. Four patients (7.5%) developed local complications at the site of iliac bone harvesting. CONCLUSION: Our stepwise surgical procedure was very effective treating aseptic atrophic nonunion of long bones. However, as this study is a retrospective review of a limited series of one surgeon's experience, prospective comparative studies with large number of patients are suitable to define the advantages and indications of the procedure herein described.

Hip avascular necrosis in a healthy pregnant woman: A case report and review of literature.

BACKGROUND: Hip pain during pregnancy is very common, but hip avascular necrosis represents a very rare entity. CASE REPORT: We report a rare case of a healthy30-year-old female patient pregnant with twins, that suffered right hip avascular necrosis in the peripartum period, her symptoms were initially neglected as a benign cause of hip pain, this led to aggressive treatment at a young age. DISCUSSION: With less than 100 cases reported in the literature, pregnancy is not a well-known risk factor for femoral head avascular necrosis and it should be differentiated from one of the more common hip pathologies in pregnancy which is the so-called "Pelvic pain syndrome" and transient osteoporosis of the hip. CONCLUSION: Having a high index of suspicion and low threshold for MRI imaging in a pregnant woman with hip pain is a must to prevent such complications.

Missed Bilateral Anterior Shoulder Dislocation With Bilateral Coracoid Fracture and Unilateral Long Head of Biceps Rupture.

Missed or chronic bilateral anterior shoulder dislocation is a rare presentation, usually secondary to epileptic attack. We present herein an exceptional case of this injury pattern, associated with bilateral displaced fracture of the coracoid process, and unilateral rupture of the long head of biceps. Treatment consisted of open reduction through osteotomy of the lesser tuberosity, with additional stabilization of the glenohumeral joint, using the Latarjet procedure by transposition of the coracoid fragment with its attached conjoint tendon to the antero-inferior glenoid rim. Rupture of the long head of the biceps required tenodesis. Temporary glenohumeral pin transfixation was performed for residual instability at the end of the procedure. Patients with postictal shoulder pain, discomfort, or disability should be investigated with adequate radiographs, in addition to CT scan or MRI when needed. Early diagnosis allows for safe closed reduction, and helps avoid late and more complex surgical treatment required for missed or chronic dislocations.
