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

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...
