Chronic elbow instabilities: Medial and lateral instability

Abstract

Elbow stability relies on a complex interaction between the bony articulations of the elbow joint, the capsuloligamentous structures, and dynamic muscle restraints. Elbow instability presents a spectrum from minor subluxation to dislocation. This review discusses the anatomy of the elbow joint, the mechanism and classification of elbow instability, and outlines treatment options available for acute and chronic elbow instability.
