Things To Know Flashcards
What is the primary restraint to varus elbow forces?
Radial lateral collateral ligament
What are signs of varus and posterior medial rotary instability?
Clicking and popping, increase pain with lateral arm raising, usually preceded by trauma, surgery is required
Varus and posterior medial rotary instability happens when…
A dislocation occurs and there’s a fx of the medial tip of the coronoid
Posterior lateral rotary instability is a result of what?
Radial collateral ligament injury
How does posterior lateral rotary instability occur?
Valgus stress with supination and axial compression
What are symptoms of posterior lateral rotary instability?
Vague elbow pain, clunking with supination, and giving way when flexed and supinated
What special tests are used to determine posterior lateral rotary instability?
Lateral pivot shift, push-up sign, press up, and chair sign
How is posterior lateral rotary instability treated?
Range locking brace for 4-6 weeks, proximal strength and movement avoiding shoulder abduction, shoulder IR, elbow flexion and extension
Valgus instability occurs acutely when? Or with overuse with what?
Acutely: FOOSH injury
Overuse: overhead throwing
What throwing phase cause Valgus instabilities?
Cocking and precocking phase due to external rotation. Increased elbow flexion decreases stress on the elbow
What are the three special tests for LET?
Cozen test, mill test, maudsley test
What is the MDC for grip strength?
11.2 and 11.5
What is the dosage for eccentric exercise? How long for ea rep? How long of rest between sets?
3x15
4 sec per rep
30 sec between sets
For LET how’s the MWM performed?
Elbow in full extension, pronated, lateral force to ulna while patient performs wrist extension or gripping
What are two tests for distal bicep tears?
Hook test and squeeze test(should supinate the forearm)
