The orthopaedic aspects of spinal muscular atrophy
EP Schwentker and DA Gibson
To clarify the role of the orthopaedic surgeon in the management of spinal
muscular atrophy, the records of 130 patients were reviewed. Seventy-three
had died. Of the remaining fifty-seven, fifty were re-examined. The
clinical manifestations of the disease, particularly those giving rise to
orthopaedic problems, were studied. At the time of review the average age
of the patients was 11.5 years. Thirty-five could not walk and all had some
degree of muscle weakness, more marked proximally and in the lower limbs.
The most common medical problem was repeated respiratory infection and the
major orthopaedic problem was scoliosis, often severe. Nine of the
thirty-five patients with scoliosis had had spine fusion. Most of them
suffered some functional loss in attaining spinal stability.
