Cannot stand on tiptoes.
The actions possible at sternoclavicular junction as seperated by the articular disk
1. Sternum/AD: Protraction/Retraction; 2. AD/clavicle: elevation/depression
Clavicle is often fractured here___; causese this thing's laceration
fracture between medial & lateral 1/3, lacerates medial cord
180 degree full abduction involves how many degrees of scapula vs glenohumeral joint
120 glenohumeral; 60 scapular
Humeral dislocation commonly occur in this direction, affecing these
dislocate ant/inf to below coracoid process, stretching axilliary and radial nerve.
Humerus fracture at greater tubercle may cause this problem and this symptom
fracture at tubercle may caust detachement of some rotator cuff muscles, the remaining subscapularis may medially rotate the humerus.
A supracondylar humeral fracture may causes this and damage this
The tricep and brachiradialis contraction shortens arm, median nerve maybe damaged. Median nerve maybe damaged.
Tennis elbow vs golfer's elbow
tennis is overstretching extensors at lateral epicondyle, golfer's overstreching flexors at medial epicondyle
