Aseptic necrosis of the femoral head as a complication of its traumatic dislocation

Abstract

The work is based on the analysis of examination and treatment results in traumatic hip dislocation (52 patients). The development of aseptic femoral head necrosis was detected in 11 patients at follow-up from 2 to 5 years. Algorithm of complex examination and treatment in traumatic hip dislocation has been elaborated for early and long-term periods after trauma. The group of high risk for aseptic femoral head necrosis development includes the patients with concomitant trauma, with posterior, obturatory and central dislocation. Rehabilitation is requiered to all patients with traumatic hip dislocation in the period from 2 to 5 years taking into account the peculiarities of hip injury. If the signs of posttraumatic aseptic femoral head necrosis are detected at early stages, then conservative treatment is indicated. In advanced process the operative treatment is indicated. Localization of necrosis area within femoral head, necrosis extension and articular surface congruence are of importance for the choice of adequate operative treatment. Roentgenologic signs of irreversibility of articular tissues destruction are the indication for total hip replacement.
