Document Summary
Acromion and clavicle glide and rotate on a small scale. Separated shoulder : sprain of capsule +/- supportive ligaments, clavicle to coracoid process separation. Mechanism of injury: direct blow to acromion process, usually shoulder is add so acromion is exposed, seen in hockey (shoulder into boards, acromion shears away from clavicle. Patient presentation: upwards displacement of clavicle because not held down, may not see in low grade enough integrity of restraining ligaments, deformity shows displacement, bruising. Aggravating motions: anything that asks the shoulder to move, 6 motions. Flexion, extension, abd, add, internal and external rotation. Internal and external don"t move this joint much only move humerus in gh joint. Flexion/abd is most painful/difficult anything that moves arms above. Require coordination between clavicle and scapula: rowing type motion that opens ac joint, cross flexion compress ac joint. Other conditions: clavicle fracture loading, upper trapezius blends into ac joint capsule. Rockwood classifications: type 1: sling for days.
