A technical report of a new versatile halo-pelvic apparatus for use in spinal immobilization is presented. Objectives. To show how simple modifications of existing external fixation devices allow a halo-pelvic fixation apparatus to be constructed. Summary of Background Data. Halo-pelvic fixation has been used successfully in the past for immobilization and correction of severe spinal deformities such as tuberculous kyphosis. With the advent of new spinal instrumentation systems and techniques, eternal immobilization of the whole spine is rarely indicated. However, on rare occasions, spine surgeons may be presented with cases in which no internal fixation has been possible. Methods. Halo-skull fixation and pelvis fixation were performed using standard techniques. A simple custom made halo connection bar was used to connect the halo to uprights from the pelvis external fixator. Because the majority of the system makes use of standard external fixation equipment,it is easy to apply and adjust. Results. Between 1997 and 2001, this frame was successfully applied to stabilize the spines of three patients with severe tuberculous kyphosis exceeding 100degrees. Conclusions. One simple modification of existing external fixation equipment has allowed a new halo-pelvic device to be constructed and used effectively to immobilize the spine.
