Spinal deformity and disability in patients with Rett syndrome

Aim Rett syndrome is a neurodevelopmental disorder starting in early childhood with devastating consequences both on the brain and on systemic neurons. Scoliosis is a common complication in most of these patients. The aim of the study was to describe the prevalence of scoliosis, classify spinal deformity, and evaluate the association between disability and scoliosis in patients with Rett syndrome. Method Twenty‐nine female patients, mean age 14 years 8 months (range 4y 10mo–33y) were included. Outcome parameters were the Barthel Index for evaluation of function, pain, analgesics, and radiological evaluation of the spine including curve size (Cobb’s method) and curve type. None of the patients had surgery before assessment. Results Twenty‐five (87%) patients had radiographically verified scoliosis. The median curve was 41° (range 15–77). The curve was classified as C‐shaped (neuromuscular) in 16 patients and double curve‐shaped in nine. Function was poorer in patients with C‐shaped curve (p
