Stabilization of the collapsing spine in duchenne muscular dystrophy

Of 41 patients with Duchenne muscular dystrophy, no ambulatory patient had scoliosis greater than 19 degrees. Non-ambulatory patients were prophylactically placed in body jackets, which kept the spine flexible and provided adequate support for sitting in the majority of patients. Ten patients had posterior spine fusion for progressive spinal collapse. The procedure was extensive with significant blood loss but boney fusion was achieved in every case. Pulmonary complications were minimized by performing preoperative tracheostomy on all patients who had vital capacities less than 40% and or non-functional coughs. Spinal fusion permitted long-term sitting stability despite the progression of the disease.
