Abstract

PURPOSE
Here we present tardy ulnar nerve palsy cases that were caused by the anconeus epitroch-learis muscle. MATERIALS AND METHODS: A 37 year old female patient presented with tardy ulnar nerve palsy findings for the elbow. During surgery, an atypical anconeus epitrochlearis muscle was observed, which originated from the triceps aponeurosis and inserted into the medial intermuscular septum. Muscle resection, nerve decompression and ulnar nerve anterior transposition were done.
RESULTS
AND CONCLUSION: Tardy ulnar nerve palsy can be associated with and caused by either an atypical or a typical anconeus epitrochlearis muscle.

Key Words: Tardy ulnar nerve palsy; Anconeus epitrochlearis muscle
