STUDY DESIGN: A case report of injury to the hypoglossal nerve (CN XII) resulting from the use of halogravity traction in a child with severe cervicothoracic kyphosis after an anterior and posterior spinal release.
OBJECTIVE: To describe one of the potential dangers of halo-suspension (gravity) traction, which has not been reported previously in the orthopedic literature.
SUMMARY OF BACKGROUND DATA: Cranial nerve injuries resulting from halo-skeletal traction are a recognized complication of such treatment, especially in patients with myelomeningocele. Halo-suspension traction using the patient's body weight as counter-traction has been recommended to provide a less rigid force and to reduce complications.
METHODS: The authors report on the mechanism of injury and clinical course in a 12-year-old boy with myelomeningocele and a bilateral CN XII injury caused by halo-suspension traction from onset to resolution.
RESULTS: This patient had dysphagia and difficulty swallowing 5 days after surgery. His wheelchair traction at this point was approximately 40% of his body weight. The traction was reduced, and a corticosteroid was administered. The patient's symptoms began to abate 5 days later. At 6 weeks after injury, his cranial nerve function was normal.
CONCLUSIONS: Although halo-suspension traction or halo-wheelchair traction may be less rigid, injury to the hypoglossal nerve can be produced with traction exceeding 40% of body weight. In the patient in the current report, resolution of this injury was complete within 5 weeks, an outcome that is consistent with those of other reported cases of CN XII injury.
