Cranial nerve palsy as a complication of operative traction.

STUDY

DESIGN

Case report.

OBJECTIVE

This report documents one case of diplopia from abducens (sixth cranial) nerve palsy after spinal surgery using a Jackson table and cranial traction.

SUMMARY OF BACKGROUND DATA: Cranial nerve deficits have frequently been described in the orthopedic literature after trauma, halo pelvic traction, and halo skeletal fixation. The theorized mechanism of injury to the abducens nerve involves stretch or traction force, which causes localized ischemia or a change in nerve position. An extensive literature search failed to show this type of injury using Gardner-Wells tongs in conjunction with the Jackson table.

METHODS

This is a case report that included a chart review, examination of the patient, and a literature search.

RESULTS

The patient had complete spontaneous resolution of abducens nerve dysfunction within 6 months.

CONCLUSIONS

It is important for the surgeon to be aware of this potential complication and to inform patients who have diplopia that develops from abducens nerve palsy that most of these cranial nerve deficits spontaneously improve.
