Treatment of severe spinal deformity remains a challenge for spine surgeons. Significant pulmonary dysfunction is frequently present, which makes the procedures more daunting. Current surgical strategies include aggressive anterior and posterior column release and osteotomy, either with a front–back or a posterior-only approach. Satisfactory correction results can be achieved. However, the risk of nerve injuries may be increased due to the rapid and strong correction and graft failure may occur because of the increased stress caused by osteopenia. Therefore, the preoperative Halo traction is recommended in the treatment of severe spinal deformity. Both spinal deformity correction and pulmonary function can be improved, and the Halo traction is a helpful adjuvant in the treatment of severe spinal deformity. In this review, the types of Halo traction used mostly in clinical practice and their beneifts are summarized.
