MOVING VALGUS STRESS TEST FOR MEDIAL COLLATERAL LIGAMENT INSUFFICIENCY OF THE ELBOW Alright, let's move on from posterolateral rotatory instability (PLRI) to medial at the elbow. If your patient is presenting after a trauma of the elbow and with medial elbow pain, one of the first things you want to test (after excluding a fracture) is the integrity of the ligaments. The moving valgus stress test is used to assess the medial collateral ligament at the elbow. According to a small study of O'Drisc

VALGUS INSTABILITY STRESS TEST FOR TEARS OF THE MEDIAL ULNAR COLLATERAL LIGAMENT The elbow joint is very similar to the knee joint. While both joints are hinge joints (when we look at the humeroulnar joint - the radiohumeral joint is a ball-and-socket joint that is restricted by the humeroulnar's shape), they are both stabilized by collateral ligaments. In order to test the medial ulnar collateral ligament, you are performing the varus instability stress test, similar to the one of the knee. No
