Valgus Stress Test
-
valgus load applied to elbow with the elbow flexed 20. Positive results = reproduction of medial elbow pain and valgus laxity greater on injured side as compared to contralateral side. Indicates MCL and varus posteromedial rotatory instability
-
may reveal valgus instability with medial and posteromedial pain indicated posteromedial elbow impingement
Moving Valgus Stress Test
Milking maneuver: tests MCL and varus posteromedial rotatory instability
Varus stress: tests lateral ulnar collateral ligament stability.
Lateral Pivot-Shift Test
-
Supine postion with forarm overhead and elbow extended.
-
Elbow is then supinated with force and flexed to >40 with a valgus load applied.
-
