Excerpt

Flexor carpi ulnaris is a superficial flexor muscle of the forearm that flexes and adducts the hand. It is the most powerful wrist flexor. Flexor carpi ulnaris originates from 2 separate heads connected by a tendinous arch. The humeral head arises from a flexor tendon origin on the medial epicondyle, while the ulnar head arises from the olecranon and upper three-fourths of the subcutaneous border of the ulna by an aponeurosis. Flexor carpi ulnaris inserts on the fifth metacarpal bone, the hook of hamate, and the pisiform bone of the wrist. Flexor carpi ulnaris inserts into the hook of hamate through the pisohamate ligament and inserts into the 5 metacarpal bone through the pisometacarpal ligament.[1]
