It presents as inability to flex the interphalangeal joint of his thumb and the distal interphalangeal joint of his index finger (can't make A-OK sign). Brachial artery Also a common complication of this fracture, but neuopraxias are more common. It presents as cold, pale, and pulseless hand. long term complication can lead to Volkmann's contracture, also known as Volkmann's ischaemic contracture, which is a permanent flexion contracture of the hand at the wrist, resulting in a claw-like deformity of the hand and fingers. Median nerve Usually the AIN which is a branch of the median nerve that's injured. Ulnar nerve Ulnar nerve palsy is rarely seen with flexion-type injury patterns. Radial nerve Radial nerve palsy is the second most common neuropraxia (close second). The most common complication of a supracondylar fracture is neurovascular injuries (8-21% of cases) as reported in some studies. Palsy to the anterior interosseus nerve at time of injury is most common, followed by brachial artery injuries. Injury to the ulnar nerve is reported as well, but it is less common. Brachial artery injury is also a common complication of this fracture, but neuopraxias are more common. It presents as cold, pale, and pulseless hand. long term complication can lead to Volkmann's contracture, also known as Volkmann's ischaemic contracture, which is a permanent flexion contracture of the hand at the wrist, resulting in a claw-like deformity of the hand and fingers.
