Document Summary

Foosh falling on outstretched hand is best way to ruin things in upper extremity fail at weakest point, can happen to be elbow often when someone is thrown into the ground coming down from high height gymnastics. When you open up/stretch medial side, you compress lateral side so you may be impacting radial head against/into humerus: candidates for injury. Ulnar nerve (if valgus is severe enough) May take down local muscles crossing by. Compression on lateral side: hammering radial head into capitulum of humerus can result in radial head fracture, esp with foosh b/c axial load. 1 jamming into olecranon process = fracture on back end via compression/impact ulna levers itself out of humerus via hyperextension, like a can opener mechanism: dislocation +/- fracture. Traction: they pull the arm away, they hold onto you and you go opp direction. , not a foosh, it"s a separation, candidates: radius is easiest to pop out.
