Study DesignThis retrospective study revlewed 100 children with clinically and electrodiagnostically proven Charcot-Marie-Tooth disease (CMTD)ObjectiveTo determine the incidence of spinal deformity in children with CMTD.Summary of Background of DataA 10percnt; incidence of hyphoscoliois has been reported.MethodsAll charts and electrodiagnostic studies were reviewed to confirm that CMTD diagnostic criteria were met. Existing radiographs on 89 children were available. Cobb angles were measured and deformity was defined as scoliosis ge; 10deg; and kyphosis 40deg;.ResultsThirty-seven of 89 CMTD children had spinal deformity. There was scoliosis in 20, kyphoscoliosis in 14, and kyphosis in 3. In children with radiographs taken at maturity, 50percnt; had deformity. The most common scolotic pattern was a thoracic curve with convexity in either direction. Spinal deformity is more likely in fermale and Type 1 patients.ConclusionThis study found an incidence of 37percnt;-50percnt; spiral deformity in children with CMTD, with female and Type 1 patients at greatest risk. However, the deformity rarely required treatment.
