KIN 361 Lecture Notes - Lecture 13: Coracoacromial Ligament, Clavicle, Supraspinatus Muscle
Document Summary
Sx: pain +1 to +2, swelling +1; reduced rom; no obvious deformity. Gr 2: tear or rupture is on ac jt but not damage coracoclavicular (cc) ligaments, clavicle bone will go up. Sx: pain +2 to +3; obvious lift of clavicle; loss of function. Gr 3: ac and cc are gone, clavical will go up until skin restricts it; flip up in the air; shoulder apparatus drops down to the rib cage; complete rupture; easy to notice. Sx: loss of structure; pain ve (usually); loss of function. Injuries sternoclavicular separation: rides up and out. Injuries shoulder impingement (impact on bone into rotator cuff tendon or bursa) A condition where the shoulders rotator cuff tendons are intermittently trapped and compressed during shoulder movements: subacromial bursitis, coracoacromial ligament, supraspinatus tendon. Scapulo-humeral rhythm: total abduction of the humerus = 180 degrees. Elbow - anatomy: radius, ulna, olecranon, capitulum, trochlea, medial epicondyle, lateral epicondyle. The motions allowed at the humero-radial joint are:
