Soft-tissue stabilizers of the elbow

Authors: Marc R. Safran, David Baillargeon

Abstract
Elbow stability is afforded by both static and dynamic structures. Static structures include the complex bony architecture and soft-tissue stabilizers. Knowledge of the anatomy and biomechanics of the stabilizers is important to understand, diagnose, and treat elbow instability. Bony anatomy, detailed elsewhere, contributes to the inherent stability of the elbow. The static soft-tissue stabilizers consist of the anterior and posterior joint capsule and both medial and lateral collateral ligament complexes. Additional stability is conferred by dynamic structures—the muscles crossing the elbow joint.
