Document Summary

Joints that make up elbow & forearm: humeroulnar: humerus & ulna, humeroradial: humerus & radius, proximal radioulnar: radius and ulna proximal ariculation, distal radioulnar: radius and ulna distal articulation. Elbow joint complex: modified hi(cid:374)ge joi(cid:374)t (cid:894)(cid:373)odified (cid:271)e(cid:272)ause it"s (cid:1007) (cid:271)o(cid:374)es i(cid:374)stead of (cid:1006) (cid:271)ut the radioul(cid:374)ar joi(cid:374)t a(cid:272)ts as 1, 2 joints, 1 degree of freedom (flexion/extension, axis of rotation extends medio-laterally through capitulum. Transverse bundle: anterior joint capsule, flexor pronator group. Extension-flexion: full range: e/f = +5 /140, functional range: e/f= -30/130, proximal and distal ru joints. Supination-pronation: normal range: s/p= 85/85, functional range: s/p= 50/50. Roll and slide in the same direction: humeroradial joint. Muscles that move the elbow: primary elbow flexors. Biceps have the most mechanical advantage because the radial tuberosity (insertion) is most superior. Your brachialis has the mechanical advantage and lifts more. Common wrist (fcu, fcr) and finger flexors (fds: flexor carpi radialis, palmaris longus, flexor carpi ulnaris.
