46 Elbow Valgus and Varus Stress Tests Elbow Valgus and Varus Stress Tests Elbow Varus Stress Test. Use: Test for varus lateral collateral ligament (LCL) instability at the elbow Procedure: Elbow flexed, slight supination, support forearm, gapping in/out to assess ligament Findings: Positive finding is pain, decreased mobility, laxity as compared with the unaffected side valgus and varus stress tests. You have 3 open access pages. These tests attempt to reveal instability to medial or lateral displacement within the knee. The valgus test involves placing the leg into extension, with one hand placed as a pivot on the knee. How to Interpret Varus Stress Test. Positive Finding: A positive test occurs when gapping or pain is noted with this test in full knee extension; this may suggest both an LCL and cruciate injury. With the knee at 20 to 30 degrees of flexion, a positive test occurs when pain is noted along the lateral knee or gapping is present. The valgus test involves placing the leg into extension, with one hand placed as a pivot on the knee. With the other hand placed upon the foot applying an abducting force, an attempt is then made to force the leg at the knee into valgus. The varus test involves applying forces to the knee in the opposite direction. The valgus stress test is closely related to the varus stress test of the same joints. A valgus test gauges lateral ligament damage on the inside of the joint, which could lead to an extended look at the elbows or knees. By contrast, the varus test determines if damage has been sustained to the other side of those joints, creating a bow-legged stance. The varus stress test at 20-30° of knee flexion is the actual workhorse test to perform when one is assessing for posterolateral instability of the knee. This test isolates out the function of the fibular collateral ligament. In effect, Valgus Stress Test at 0 The examiner should passively bend the affected leg to about 30 degrees of flexion. While palpating the lateral joint line, the examiner should apply a varus force to the patient's knee. A positive test occurs when pain or excessive gapping occurs ( some gapping is normal at 30 degrees ). A positive test is valgus movement of the leg with or without pain. For the varus stress test, force is from the opposite direction, i.e. push to medial side and feel the opening of lateral side (lateral collateral ligament). A positive test is varus movement of the leg with or without pain, depending on acute or chronic condition. Valgus and Varus Stress Test. Name. Purpose. Description. Sensitivity, Specificity. Validity, Reliability. Likelihood Ratio +/-Valgus Stress Test. An assessment for one-plane medial instability (gapping of the tibia away from the femur on the medial side). [1] The therapist then applies a varus force to the elbow. This test is considered positive if the patient experiences pain or excessive laxity is noted and compared to the contralateral side. The test can be repeated in varying degrees of elbow flexion, but generally it is positioned between 5 and 30 degrees.
