Spinal deformities in patients with Friedreich ataxia: a review of 19 patients.

Nineteen patients with Friedreich ataxia and scoliosis were reviewed. The curve pattern was thoracic in six, thoracolumbar in six, double thoracic and lumbar in two, and double thoracic and thoracolumbar in five. Scoliosis was associated with hyperkyphosis in eight patients. Nonoperative treatment with braces was unsuccessful because of either increase of the curve despite the brace or difficulties with balance and coordination. Twelve patients underwent posterior spinal fusion with instrumentation. Average follow-up was 32 months. Postoperative immobilization was used in 10 patients and resulted in functional problems in only three. All fusions were solid at follow-up.
