Delayed ulnar nerve palsy after open reduction and internal fixation of medial epicondylar fractures

Abstract

We present two cases of patients with delayed ulnar nerve palsies after operative fixation of displaced medial epicondyle fractures. These fractures are common childhood injuries and the optimal management for the ulnar nerve is not universally agreed. The ulnar nerve is at risk of compression distal to the elbow and where surgical decompression is selected, care must be taken to ensure that this is complete.
