Tardy ulnar nerve palsy is due to
Cubitus valgus
Fixation of the nerve in the groove by osteoahritis
Excision of elbow joint
Fracture of internal condyle
Tardy ulnar nerve palsy is due to cubitus valgus. Fracture of the lateral condyle of humerus in the long run can lead to complications such as Cubitus valgus. Friction neuritis of the ulnar nerve as it moves over the medial epicondayle every time the elbow is flexed and extended may result in a late ulnar nerve palsy called as 'TARDY ULNAR PALSY'.
