COMPLICATIONS OF POLIOSCOLIOS SURGERY

This is a retrospective study of 83 patients with polioscoliosis, treated surgically in Shafa hospital (1970-1997), and the results are as Follow: implant failure: 15 cases (18%), pʹseudoar throsis: 12 cases (14.5%); deep infection: 4 cases (4.5%); superficial infection: 3 cases (3.6%); cast sore: 17 cases (20.5%); and loss of correction: 28 cases (33.7%). Implant failure was more common in Harrington distraction system (HD) and Harrington with Zeilke system, and was rare in Harrington with sublaminar wiring (HD+SLW). Pseudoarthrosis was common in the HD and was very rare in the HD+SLW. Also pseudoarthrosis was more common in the fusion with sacral involvement, posterior fusion alone, thoracolumbar and lumbar curves, than Fusion without sacral involvement, anterior with posterior fusion, and thoracic curve. So in polioscoliosis with thoracolumbar and lumbar curves that need fusion with sacral involvement, the most appropriate procedure is anterior and posterior fusion with HD+SLW instrumentation.
