The lateral supracondylar ridge is a prominent, rough margin on the lower part of the lateral border of the humerus. It presents an anterior lip for the origin of forearm extensors, including the brachioradialis muscle above, and the extensor carpi radialis longus muscle below.[1] It also presents a posterior lip for the triceps brachii, and an intermediate ridge for the attachment of the lateral intermuscular septum.
