These articulations provide a high degree of inherent stability to the elbow and are supported by several ligamentous structures—the radial collateral, ulnar collateral, annular ligaments, and anterior capsule (Fig. 14–1). The biceps, triceps, brachialis, brachioradialis, and anconeus provide muscular dynamic stability.
