Question

Quizplus · Accepted Answer

In full elbow extension, varus stability is provided by the configuration of the joint surfaces, joint capsule, and lateral collateral ligament. The joint surfaces are congruent in extension, which helps resist varus forces. The joint capsule and lateral collateral ligament provide additional stability by limiting excessive lateral movement of the joint. The medial collateral ligament primarily resists valgus forces, while the annular and oblique cords are involved in maintaining the stability of the proximal radioulnar joint, not the elbow joint. The anterior and posterior ligaments also play a minor role in the stability of the elbow joint.
