Complications Related to Perioperative Halo Traction in the Treatment of Severe Scoliosis

PURPOSE: We analyzed consecutive cases of severe scoliosis treated with perioperative halo traction.
METHODS: 27 pts. with severe scoliosis of various etiologies were analyzed. Possible treatment protocols included traction-PSF, ASF-traction-PSF, traction-ASF-traction-PSF, and other.

RESULTS: There were 5 traction-related problems: pin loosening (2), and nystagmus (2) or nausea (1) that resolved with reduction of traction. Postop there were 3 sup. wound infections, 1 rod migration, 2 temporary brachial plexopathies, and 1 pseudarthrosis. There were no permanent neurologic deficits.

CONCLUSIONS: Perioperative halo traction is safe and effective method to assist with correction of severe scoliotic curves. It is important to recognize the signs of excessive traction, but major complications including neurologic were avoided during treatment of these complex spinal deformities.
