Abstract

STUDY DESIGN:

A retrospective analysis of patients that underwent perioperative halo-gravity traction as an adjunct to modern instrumentation methods in the treatment of severe scoliosis and kyphosis.

OBJECTIVE:

To review the clinical and radiographic results of perioperative halo-gravity traction in several time periods.

SUMMARY OF BACKGROUND DATA:

Few reports to our knowledge review the use of perioperative and intraoperative halo-gravity traction in this patient population.

METHODS:

A total of 33 patients with severe operative scoliosis, kyphoscoliosis, or kyphosis were studied based on hospital records, standing pretreatment, traction (before anterior/posterior fusion), postoperative (each stage), and final radiographs. Patients were analyzed by age at date of examination (range, 2-20 years; mean, 13.8 years), gender (18 male, 15 female), major coronal curve magnitude (range, 22 degrees-158 degrees; average, 84 degrees), major compensatory coronal curve magnitude (range, 8 degrees-123 degrees; average, 51 degrees), major sagittal curve magnitude (range, 13 degrees-143 degrees; average, 78 degrees), traction protocol, and procedure type. Halo-traction-related, short- and long-term complications were noted in each case.

RESULTS:

The major coronal curve reduced 38 degrees or 46% after posterior spinal fusion compared to pretreatment radiographs. At an average of 44 months radiographic follow-up (range, 24-107 months), the loss of correction averaged 7 degrees for major coronal curves and 4 degrees of thoracic kyphosis. Clinical complications were noted in the perioperative and long-term time periods.

CONCLUSIONS:

The treatment of severe scoliosis can be very challenging despite the benefits of modern instrumentation methods, especially if there is a significant kyphosis or a history of intraspinal pathology. Halo-gravity traction is a safe, well-tolerated method of applying gradual, sustained traction to maximize postoperative correction in this difficult population. There were no permanent neurologic deficits in this series.
