An unusual case report of tardy ulnar nerve palsy following neglected fracture non-union of me dial epicondyle humerus

Abstract

Tardy ulnar nerve palsy is a condition presented as late onset ulnar neuropathy. Most commonly occurred as a delayed complication of non-union of lateral epicondyle humerus with valgus deformity. Whereas tardy ulnar nerve palsy occurred as a complication of fracture non-union of medial epicondyle was rare and a very few cases were reported in literature. We report a case in a 15 year old boy with tardy ulnar nerve palsy after neglected fracture non-union of medial epicondyle of humerus on left side, patient presented with tingling and numbness of medial side two fingers with left hand weakness. We treated him operatively by tension band wiring and olecranon bone grafting for fracture non-union medial epicondyle of left humerus and ulnar nerve exploration and anterior transposition was also done.
