QuestionChoice
Cubital tunnel syndrome is compression of the ulnar nerve as it passes through the cubital tunnel at the elbow. This patient did not injure his elbow in his fall, making this incorrect. Cubital tunnel syndrome would present with pain at the elbow (medial), with sensory disturbance of the 4th and 5th digits, hypothenar eminence, and ulnar side of the dorsum of the hand.

Cubital tunnel syndrome
QuestionChoice
This is a condition resulting from progressive fibrotic thickening of the palmar fascia and is not related to traumatic injury. It is most often idiopathic and would cause a fixed flexion deformity of the 4th and 5th digits.

QuestionChoice
The patient has likely suffered a scaphoid fracture following a fall onto an outstretched hand. The major risk of scaphoid fracture is avascular necrosis, which would present with pain and stiffness at the wrist. This complication is due to the artery supplying the scaphoid bone being at increased risk of damage due to its anatomical position in the hand and the fact that it provides a retrograde blood supply.

Avascular necrosis
QuestionChoice
The radial nerve may be damaged at a number of sites in the arm. However, this is unlikely given the mechanism of this injury. A radial nerve injury can result in reduced sensation in the anatomical snuff box, but is less likely to cause pain here. Damage may result in wrist/finger drop.

d
Radial nerve palsy
QuestionChoice
Carpal tunnel syndrome is due to entrapment of the median nerve within the carpal tunnel of the wrist. It is often idiopathic, but may occur secondary to other conditions. The median nerve is unlikely to be affected when falling on an outstretched hand, and would not cause pain within the anatomical snuff box.

A 24-year-old man falls onto an outstretched hand whilst playing football. He experiences bruising and tenderness on palpation of the anatomical snuff box, with pain on telescoping the thumb.

Based on the likely injury, which of the following complications is the patient most at risk of developing?
