WebThe olecranon is a bony prominence of the ulna that represents that bone’s most proximal posterior surface at the elbow. While the olecranon is an attachment site for several muscle groups including the flexor carpi ulnaris and anconeus, the major muscle attachment is that of the triceps. The olecranon can thus be fractured (avulsed) by a ... WebThe coronoid process is a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, and of considerable strength. Its apex is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus. Its upper surface is smooth, concave, and forms …

WebRecent evidence suggests coronoid tip fractures have a role in the instability. We sought to quantify the capsular and brachialis attachments of the ulnar coronoid process to better understand why instability occurs. We prepared eight fresh-frozen cadaveric specimens to ascertain the specific attachment locations. WebSep 19, 2024 · Attachments Musculotendinous.
