Abstract

Introduction Aim of this study was the evaluation of technical surgical replacement with shortening osteotomy and repositioning it in paleocotile in iliac Crowe 4 dislocations. Materials and methods Thirty-five cases treated by a single surgeon with the technique of repositioning in paleocotile and femoral shortening osteotomy. Description of pre-operative planning and tests and postoperative results. Results The authors report good and excellent results with recovery of pain, length of leg and step pattern. Discussion The authors give absolute chirurgical indication in unilateral dislocation with important hip pain an relative chirurgical indication in case of purely functional disorder. In bilateral dislocated hip, the indication is to be evaluated very carefully, because it may be preferable to refrain from surgery. The surgery should be performed on clinical symptoms and rarely acclaimed as a preventive measure. The technique need an accurate preoperative planning in positioning acetabular cup in paleocotile, using CT scan. If is needed a hip centre of rotation lowering higher than 3-4 cm is indicated subtrochanteric femoral shortening osteotomy and the use of special stems. Conclusions The authors recommend this technique for this type of disorder. Excellent results and good restore of biomechanical parameter are achieved. We have to emphasize, however, that it is not simple technique and requires a skilled surgeon and an absolute respect of planning and surgical steps.
