A new halo-pelvic apparatus.

Study Design: 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.
