What specific ligament is assessed during the Varus Stress Test at the elbow?

The Varus Stress Test at the elbow specifically assesses the integrity of the lateral collateral ligament. This test is performed by applying a lateral force to the elbow to evaluate the stability of the outer compartment of the elbow joint. If the lateral collateral ligament is compromised, typically by injury or laxity, the test will elicit excessive movement or pain, indicating that the ligament may be damaged or torn.

While the medial collateral ligament provides stability on the inner side of the elbow and is evaluated during the Valgus Stress Test, the Varus Stress Test is solely focused on the lateral side. The anterior and posterior cruciate ligaments are located in the knee joint, making them irrelevant in the context of elbow assessment. Thus, the lateral collateral ligament is the correct answer as it is specifically targeted during this particular test, providing insight into the elbow's lateral stability and overall function.
