Tardy ulnar nerve palsy may develop after malunited fractures of the lateral humeral condyle in children, displaced fractures of the medial humeral epicondyle, dislocations of the elbow and contusions of the nerve. Tardy ulnar nerve palsy may also develop in patients who have a shallow ulnar groove on the posterior aspect of the medial humeral epicondyle.
