title: [Femoral shortening osteotomy for chronic hip dislocation in patients with cerebral palsy].
abstract: Hip dislocation of several years duration in cerebral palsy needs treatment only if the patient has serious complaints. With the aim of reducing pain and problems with sitting function and perineal hygiene, we performed shortening osteotomy of the femur in 15 patients (12 girls and 3 boys) with spastic quadriplegia or diplegia at mean age of 14 (8-26) years. The patients were severely mentally and physically retarded, and only one patient had gait function, with support. A subtrochanteric shortening osteotomy of 3-5 cm was performed. The mean follow-up period was 5 (1-10) years. The symptomatic effect of the operation was good. The patients and parents were satisfied because the pain disappeared and the patients had less spasticity and stiffness. Complications were seen in two patients in the form of skin necrosis under both heels; this was caused by the plaster. Although reduction of the dislocation was not the aim of the surgery, radiographs at follow-up of 16 operated hips showed that five hips were reduced, whereas 11 hips remained subluxated or dislocated. We conclude that shortening osteotomy of the femur produces good symptomatic effects, probably due to reduction of the abnormally high muscle tension across the hip joint.
