Use of external fixator in the postoperative management of sciatic nerve injuries

Immobilization of lower limb following neurorrhaphy for sciatic nerve injuries poses a difficult clinical situation both for the surgeon and for the patient. In this article, we describe a new technique for maintenance of lower limb in desired position of extension at hip and flexion of knee without application of spica cast using an external fixator. In this method, a spanning external fixator across the knee and hip joint is applied in the desired position following neurorrhaphy, and both joints are sequentially brought back to normal position. Clinical follow-up of 2 cases is also presented with preservation of range of motion at hip and knee joint as well as good functional outcome of nerve repair.
