Preoperative management through modified halo-pelvic distraction assembly in a case of severe thoracic spine kyphosis.

The application of halo-pelvic distraction before corrective surgeries can not only reduce the severity of the kyphotic deformity making the definitive surgery easy but neurology can also be improved. The high-risk complications associated with acute correction of deformities can be minimized using our modified halo-pelvic distraction device.
