KYPHECTOMY IN MYELOMENINGOCELE - EXPERIENCES 1971-1990

Between 1971 and 1990 33 kyphectomies were performed at the Orthopaedic Hospital, University of Heidelberg. The average age at time of surgery was 5 years/5 months; the follow-up period was 5 years. The best results were obtained in the group with. congenital rigid kyphosis. A marked postoperative deterioration was considered in patients with a flexible paralytic kyphosis, probably due to a too short area of fusion. In 19 patients the correction of the kyphotic deformity was the prerequisition for being provided with orthotic devices. The most serious complication was the intraoperative death of 3 patients. It can be presumed, that after transection of the spinal cord a non-functioning CSF-shunt lead to an acute elevation of the intracranial pressure. Therefore an adequately functioning shunt must be secured preoperatively.
