Complications of halo-pelvic traction. Case report.

When halo-pelvic traction is applied at a rapid rate it may induce cranial nerve palsies. The sixth, ninth, and tenth cranial nerves appear to be the most vulnerable. A proposed etiology is the stretching of these nerves resulting in a compromised blood supply with a consequent temporary paralysis which usually improves within 8 to 10 weeks.
