The Halo-pelvic traction has been considered as a powerful and strong method for correction of the severely deformed rigid spine whether it is kyphotic or scoliotic. It also affords firm stabilization during the operation and postoperative management with immobilization for a long time. Ambulation with this instrument enhances the usefulness. We have succeeded in treating and correcting 6 cases of Tuberculous Kyphosis, and 3 of which accompanied paraplegia. Especially one case of severe kyphosis, 78 was corrected to 20 and anterior strut graft was accomplished with vascuiarized free fibular graft with aid of microvascular technique. The correction rate was 38% in average. No significant complications have developed except osteoporosis of the spine.
