Thoracolumbar scoliosis in cerebral palsy. Results of surgical treatment.

Of 294 patients with cerebral palsy seen from 1960 to 1972, forty-two had clinically significant lumbar and thoracolumbar scoliosis (31 to 135 degrees) and thirty-three were treated by spine surgery: ten by Harrington instrumentation and posterior spine fusion, eighteen by the Dwyer procedure and anterior fusion, and five by a two-stage combined anterior and posterior fusion. Evaluation of the results after eighteen to sixty-eight months showed: relief of pain in seventeen cases, improved sitting tolerance in seventeen, less nursing care needed in three, less equipment required in six, ability to use equipment providing more function in three, placement in a facility where less care was required in two, and improved eating patterns in two. Only the combined procedure appeared to give adequate correction and a low incidence of pseudarthrosis.
