epicondyle

When the extensor carpi radialis brevis (ECRB) muscle, which helps stabilize the wrist when the elbow is straight, is overused, the tendon can develop microscopic tears where it attaches to the lateral epicondyle, a bump on the end of the upper arm bone, the humerus.

His left arm was stuck in flexion, with an inability to fully extend it; his left lateral epicondyle was enlarged and inflamed around the joint; his PIPS/DIPS were inflamed bilaterally.

In addition, del Sol & Vieira (1989) described the chondroepicondilar muscle, supernumerary fascicle of the pectoralis major muscle, that extends from the six and seventh costal cartilages and ascend with the muscle fibers and generates a long and thin tendon that extends from the anterior lip of the intertubercular groove to the medial epicondyle of the humerus.

In a study on iliotibial tract, the tract was attached to the femur along the linea aspera from the greater tronchanter to, and including, the lateral epicondyle of the femur by coarse fibrous bands.7 Linea aspera has important prominence which protects the femur against bending when bearing the stresses and loads.

The mnemonic "CRITOE" (Capitellum, Radial head, Internal (medial) epicondyle, Trochlea, Olecranon and External (lateral) epicondyle) can help diagnose certain fractures, particularly those where an ossification center 'appears' out of the expected order.

A number of uncertainties surround the evaluation and treatment of medial epicondyle fractures of the humerus in children.

Palmaris longus (PL) is a thin muscle which originates from the medial epicondyle by a short belly, located superficially in the middle of the anterior aspect of the forearm.

Use of the epicondylar axis was logical because it essentially paralleled the center of knee rotation and was applied to the femoral rotational alignment during TKA.[14],[15] The surgical epicondylar axis was identified by two points, one on the medial epicondyle (sulcus) and one on the lateral epicondyle (prominence).[16] The AIN was used as a bony anatomical landmark to identify the proper entry point [Figure 2]b.

Also known as tennis/golfer's elbow, lateral/ medial epicondyle pain is thought to result from overuse of the common wrist extensor/ flexor muscle origins at the site of the myotendinous junctions.

Two small incisions were made, one just beneath and off the superior pole of patella and another starting at the adductor tubercle and ending just distal to the medial epicondyle of the femur.

The chronological order of appearance of the elbow ossification centers follows this rule: capitellum, radial head, medial epicondyle, trochlea, olecranon, and lateral epicondyle.

The concentric and eccentric phases of shoulder abduction were identified by calculating the midpoint from the medial and lateral epicondyle reflective markers.
