Ans. b (Lateral condyle) (Ref. Maheshwari orthopedics 4th/87)Complications of fracture of lateral condyle of humerus^# Nonunion# Cubitus valgus deformity- May reult in late ulnar nerve palsy (tardy ulnar nerve palsy)- Mild deformity needs no Rx- Moderate to severe may need supracondylar osteotomy.- Anterior transposition of ulnar nerve in early tardy ulnar nerve palsy.# OA of elbow.Fracture medial epicondyle of humerus^# More common than fracture of lateral epicondyle# Associated with posterior dislocation of elbow# May be associated with ulnar nerve injury.Complications of intercondylar fracture of humerus^# Stiffness of elbow (may be associated with myositis ossificans)# Malunion (may lead to cubitus valgus/varus deformity)# OAComplications of supracondylar fracture of humerus||||Immediate (at time of )Early (within 1st 2-3 days)Late (weeks to months after )1. Injury to brachial artery2. Injury to radial & median nerve1. Volkman's Ischemia (Mcly affected=FPL & medial FDP)1. Malunion ("Gun-stock" deformity; cubitus varus; commonest complication;Rx is french osteotomy)2. Myositis ossificans3. VIC (Rx is turn-buckle splint/ Maxpage operation).
