Struther’s ligament

Distinct from struthers arcade which is a normal finding. The supracondylar process (SCP) is an anatomical variant located 5–7 cm above medial epicondyle, present in 0.7–2.7% of population.

Struther’s ligament bridges the SCP to the medial epicondyle. The median nerve and brachial artery pass underneath, the ulnar nerve may also. Usually asymptomatic, but occasionally may cause typical median nerve syndrome.
