Increased prevalence of scoliosis in Turner syndrome.

Turner syndrome (TS) is associated with multiple skeletal abnormalities. However, the prevalence of scoliosis in children with TS has not been reported in the orthopaedic literature. The purpose of this study was to determine the prevalence and characteristics of scoliosis in these patients. The authors performed a retrospective study of 43 patients with TS and found 5 children with a curve >10 degrees. The prevalence of scoliosis in this TS population, 11.6%, was significantly greater than the reported prevalence of idiopathic scoliosis in normal girls, 2.4%. The mean age of onset was 9 years 11 months. All curves were >34 degrees, with curves consisting of a right thoracic or S-shaped (larger lumbar segment) pattern. At the time of scoliosis presentation, two patients were not receiving growth hormone therapy. The results of this study suggest that children with TS need to be examined and closely monitored for progression of scoliosis by orthopaedists. Although curve progression can occur during growth acceleration, a direct causal association with growth hormone has not been established.
