Document Summary
Hyperextension often result of fall, hand blocks fall, weight falls on elbow: anterior capsule and elbow flexors. Biceps brachii, brachialis, etc: dislocation potential. Olecranon process hooks into back of humerus. Hook can pivot out and result in dislocation. Traction injury: pulling apart, reverse of axial load, take radial head and slip through the annular ligament that holds in place against ulna, traction mechanism. Valgus sprain mucl (medial ular collateral ligament: foosh (fall on outstretched hand) All of body weight lands on hand not designed this way) Rom: extension is most aggravating, flexion less of a problem, pronation and supination more than other sprains. Muscle guarding: elbow flexors increase activity to hold in flexed position, triceps tend to quieten a bit. Hinge bracing: prevent extension the whole way in the short term. As time passes, can allow more range to be available: some limit valgus. Normal extension is valgus so limiting normal movement: may not need to be specific.
