Background Balanced forces around the hip joint are critical for normal development of the hip joint, so it should be considered in every hip reconstructive procedure. Methods In seven children with complete destruction of the femoral head and neck due to septic arthritis, a reconstructive hip surgery was done to reconstruct the femoral head without sacrificing the greater trochanter and its muscles completely. The technique consists of a modified greater trochanter arthroplasty with only a medial portion of the greater trochanter and a varus femoral osteotomy.Results The average age of the children at surgery was 17 months (range 8-36 months) and the patients were followed for an average of 16.6 years (range 10.9-20.1 years). The average number of second operative procedures for each patient was 2 (range 1-4). The followup evaluation for each patient included documentation of pain, hip range of motion, and assessment of gait. In addition, the current leg-length discrepancy, final coverage and stability of the hip joint were documented. At final evaluation, all patients had a pain-free stable hip and two patients had near-normal hip range of motion. All patients have had satisfactory surgery results. Conclusions By this kind of hip reconstruction, we could provide a stable painless hip joint with special attention to the greater trochanter's role on hip biomechanics.

a b s t r a c tObjective: Regarding the frequency of cubital tunnel syndrome, varieties of treatment modalities, and ambiguity of anterior subcutaneous transposition of ulnar nerve method, we aimed to evaluate the efficacy of this procedure in patients with cubital tunnel syndrome referred to Taleghani hospital between 2006 and 2009. Methods: This study was a case series including all referred patients with definite diagnosis of cubital tunnel syndrome, treated by anterior subcutaneous transposition. Treatment results were measured according to modified Bishop rating system, and were ranked into excellent, good, fair, and poor. Variables such as gender, age (less/more than 45 years), causation, and initial severity, determined by Dellon criteria preoperatively, were analyzed by Fisher's exact test. Results: This study was performed on 26 eligible cases including 29 elbows, 38% males and 62.1% females, with mean age of 44.5 years (ranging 23-72 years). In a 12 months follow-up post-operatively, 62% showed excellent, 20.7% good, and 17.3% fair, with no poor result. In a 1-12 months follow-up post-operatively, results showed improvement, and initial severity and old age were demonstrated to significantly affect treatment results (P < 0.07). Conclusion: Though considered standard of care, the present study suggests that criteria for surgical techniques of ulnar nerve decompression, e.g. simple decompression vs. more extensive repair as in the present cohort, should be revised by controlled prospective studies.
