MANAGEMENT OF SCOLIOSIS DUE TO SYRINGOMYELIA IN CHILDHOOD AND ADOLESCENCE

To determine the effect of syringomyelia treatment (drainage) on the efficacy of orthotic management and safety of operative management of an associated scoliosis, the records of four boys with scoliosis due to syringomyelia were reviewed. The average follow-up was 8 years. On presentation, all had an abnormal neurologic examination. Each syrinx was treated by laminectomy and insertion of a syringosubarachnoid shunt. After drainage, three of four improved neurologically. Two older patients underwent uneventful posterior spinal fusion with Harrington distraction instrumentation after their drainage procedures. One boy developed kyphosis at the site of his laminectomy. Two young patients, whose curves were initially well controlled with bracing, developed continued curve progression over time. Drainage of the syrinx delayed but did not prevent curve progression in immature patients, but did allow use of distraction instrumentation without complication for operative management of the associated scoliosis. © 1990 Raven Press, Ltd., New York.
