Deep peroneal nerve palsy after opening wedge high tibial os
Peroneal nerve injury is one of the major complications that may occur after closing wedge high tibial osteotomy (CWHTO). In contrast, the reduced risk of the peroneal nerve injury has been considered as one of the advantages of opening wedge HTO (OWHTO).

A 61-year-old male who underwent OWHTO showed a dropped big toe immediately after surgery. Injury of deep peroneal nerve was confirmed by electrodiagnostic study. It was probably caused by a posterolaterally protruded screw. The protruded screw was replaced with a shorter one 3 weeks after OWHTO.

The motor weakness and sensory reduction were completely recovered at 9 months after surgery.
