One of the mysteries of the English language finally explained.
A bony prominence at the elbow, on the upper end of the ulna.
- ‘The olecranon is the bony landmark identified as the elbow in surface anatomy.’
- ‘A sesamoid bone is occasionally contained within the tendon of the triceps muscle proximal to the olecranon.’
- ‘On physical examination, a swollen, fluid-filled sac is noted and palpated over the olecranon.’
- ‘Radiographs may show osteophytes of the olecranon tip and the medial wall of the olecranon fossa, hypertrophy of the olecranon and loose bodies.’
- ‘It may also be worth noting that the area of origin for the m triceps is extensive, and the olecranon process of the ulna is notably large.’
- ‘Ulnar and radial ligamentous stabilities are assessed with the patient's forearm flexed at 20 degrees to unlock the olecranon from its fossa.’
- ‘In injuries to the elbow, the most common type was contusion with laceration or bursitis around the olecranon bone; falling and a blow against the surface of the ice was a typical mechanism of injury.’
- ‘Tenderness of the triceps tendon is present at or just superior to the attachment on the olecranon and increases with extension performed under resistance.’
- ‘In children, cuff bladder width should be at least 40 percent of the arm circumference halfway between the olecranon and acromion; the cuff should then cover 80 percent or more of the arm circumference.’
- ‘They occur in the lungs, heart, kidney, and dura mater, in addition to the extensor surface of the forearm, olecranon, Achilles tendons, and ischial area.’
- ‘Valgus instability can be detected by applying valgus stress to the elbow at 20 [degrees] to 30 [degrees] of flexion to unlock the olecranon from its fossa.’
- ‘With the elbow flexed at 90 degrees, the needle is inserted 0.5 cm into the skin between the olecranon and the medial epicondyle, and 3 to 5 ml of solution is injected.’
- ‘The normal end-feel in extension should be the firm sensation of bone contacting bone as the olecranon tip contacts the distal humerus in the olecranon fossa.’
- ‘If concomitant valgus extension overload with olecranon osteophytes is suspected, a vertical posterior capsulotomy is placed proximal to the fibers of the posterior band of the ulnar collateral ligament to expose the olecranon tip.’
- ‘The distal articular surface has a very wide medial epicondyle and the olecranon fossa is shallow.’
- ‘Biceps and triceps skinfolds were measured at the level of nipple line and midway between the acromion process of the scapula and the olecranon process respectively.’
- ‘Bursitis of the elbow Bursitis in the elbow is often associated with the olecranon bursa,…’
- ‘Essential landmarks to palpate before performing this injection are the soft tissue at the center of the triangle formed by the lateral olecranon, the head of the radius, and the lateral epicondyle.’
- ‘Patients with longstanding gout may have tophi over the olecranon prominence, first metatarsal joints, or pinnae.’
- ‘He developed various prosthetic devices, including a bi-cortical screw fixation for the olecranon.’
Early 18th century: from Greek ōle(no)kranon, from ōlenē ‘elbow’ + kranion ‘head’.
