A 9 year old child presents to the ED with a painful swelling of the left elbow after having fallen onto the outstretched left hand while playing football.. The child is unable to flex his index finger or make a circle with the index finger and thumb. An X ray shows a supracondylar fracture. The nerve most likely to be injured is the:
A. Ulnar nerve.
B. Median nerve
C. Radial nerve
D. Musculocutaneous nerve.
E. Axillary nerve.
B. Median nerve
Explanation: The radial nerve supplies posterior of arm - triceps, posterior forearm muscles and they are all extensors so a radial nerve injury - patients can’t extend fingers so their hands are curved. If it’s a radial nerve injury, extension is the problem not flexion.
The axillary nerve supplies deltoid and arm area (not forearm). The musculocutaneous nerve supplies anterior compartment of arm (upper bit, not forearm). The lateral side of the hand is supplied by the median nerve and the medial side of the hand is supplied by the ulnar nerve. In an ulnar nerve injury, the patient will have trouble flexing the last two digits.
