Posterior Interosseous Nerve Palsy and Proximal Radio-Ulnar Joint Locking after Radial Head and Neck Fracture: A Case Report

Abstract

Radial head fractures are common injuries which can be managed conservatively in the absence of instability or mechanical block at the elbow. We report a case of radial head and neck fracture which uniquely incorporates two rare complications: posterior interosseous nerve (PIN) palsy, and locking of the proximal radio-ulnar joint. The causative mechanisms are described with review of the relevant literature.

Key words

Posterior interosseous palsy - joint locking - radial head - radial neck - fracture
