Median nerve palsy after operative treatment of olecranon fracture.

Olecranon fracture is not an uncommon fracture in clinical practice. Simple olecranon fracture usually heals quite well without any types of iatrogenic complications. Despite close proximity of the fracture to the nerve, median nerve palsy after operative treatment of olecranon fracture is a rare complication. To the authors' knowledge, this complication has not been previously reported in the Thai or English literature. The authors present a patient who had median nerve palsy after tension-band wiring for olecranon fixation. Intraoperative finding revealed that the median nerve was injured by the tip of K-wire. While this complication is uncommon on a per-person basis, it may results in serious complication, such as nerve palsy or limb ischemia. Orthopedic surgeons must remain vigilant with regard to any type of internal fixation in the upper extremity because the risk of neurovascular injury is high.
