title: Posterior instrumentation and fusion of the thoracolumbar spine for treatment of neuromuscular scoliosis.
abstract: We reviewed the clinical and technical outcomes of 25 patients with neuromuscular scoliosis, who were treated by Luque instrumentation and posterior spinal fusion from the upper thoracic spine to L5 between 1981 and 1988. A mean curve correction of 46% was obtained operatively with a mean 8 degrees loss of correction during the follow-up period that ranged from 1.9 to 9.4 years (mean, 5.5). Pelvic obliquity was improved 50% from a mean of 16.1 degrees to a mean of 8.1 degrees in 24 patients for whom data were available. At final follow-up, the mean pelvic obliquity increased to 11.4 degrees with only two patients increasing > 8 degrees. The cause for major postoperative increase in pelvic obliquity was continued anterior spinal growth with torsion of the fusion mass and was not related to changes limited to the L5-S1 motion segment. Posterior fusion and instrumentation from the upper thoracic spine to L5 without anterior fusion provides adequate correction and control of spinal deformity for many patients with cerebral palsy. Those patients with significant growth remaining, or with severe deformities, may benefit by preliminary anterior release and fusion or inclusion of the pelvis and sacrum.
