[The effect of halo-gravity traction in the preoperative treatment of neuromuscular scoliosis].
The purpose of this study is to evaluate the influence of halo-gravity-traction on paralytic scoliosis in various neurologic diseases. Between 1980 and 1993 preoperative halo-gravity-traction was applied in 32 patients with paralytic scoliosis (23 patients with myelomeningocele, 6 patients with poliomyelitis, 3 patients with cerebral palsy). In the myelomeningocele group the average curvature before treatment was 97.8 degrees, after surgery 45.1 degrees; which is an improvement of 53.9%. Halo-gravity-traction accounted for 12.8% improvement. In the poliomyelitis group the average curvature before treatment was 104.3 degrees, after surgery 58.0 degrees; which is an improvement of 44.4%. Halo-gravity-traction accounted for 16.9% improvement. In the cerebral palsy group the average curvature before treatment was 75.0 degrees, after surgery 39.0 degrees; which is an improvement of 48.0%. Halo-gravity-traction accounted for -2.7% improvement. If there is an effect the question remains, whether this will have consequences for the surgical outcome. The comparison between good and bad responders with the surgical result shows, that this result is independent of the halo-gravity-traction. From this results we draw the conclusion, that preoperative halo-gravity-traction can not be recommended in paralytic scoliosis.
