Surgical dislocation of the hip remains an important alternative in hip preservation surgery, especially when a dynamic access to the hip is needed and arthroscopy is not a suitable option. We describe a novel technique for operative dislocation of the hip without trochanteric osteotomy and the clinical results of our patients. Surgical dislocation of the hip without trochanteric osteotomy was done through a modified lateral approach in all of the cases. A review of demographic, clinical, and radiological data was done in all of the patients operated with this technique between 2010 and 2015. Complications, walking aids, weight-bearing status, and modified Harris Hip Score (mHHS) were also recorded. Six surgical dislocations of the hip were carried out. Indications were tumor resection in five and bulletectomy in one hip. There were two women (four hips) and two men. Mean age was 19 ± 3.8 years. Median follow-up was 2.5 years (range 2-4.5 years). Median mHHS was 92 (90-96). There were no intraoperative nor postoperative complications. Surgical dislocation of the hip without trochanteric osteotomy through a modified lateral approach appears to be a safe, simpler, and effective alternative.

D005097 Exostoses, Multiple Hereditary Hereditary disorder transmitted by an autosomal dominant gene and characterized by multiple exostoses (multiple osteochondromas) near the ends of long bones. The genetic abnormality results in a defect in the osteoclastic activity at the metaphyseal ends of the bone during the remodeling process in childhood or early adolescence. The metaphyses develop benign, bony outgrowths often capped by cartilage. A small number undergo neoplastic transformation.
