The anterior oblique component of the medial collateral ligament is the mainstay of elbow joint stability, yet chronic elbow instability remains an uncommon lesion. The study aims to repair chronic elbow instability by restoring medial collateral ligament function. The authors recommend anatomically reducing medial epicondyle fractures, using open reduction when necessary, to restore ligament function. Fibrous union of minimally displaced medial epicondyle fractures can lengthen and compromise medial collateral ligament function.
The anterior oblique component of the medial collateral ligament of the elbow is the mainstay of joint stability. Fractures of the medial epicondyle must be anatomically reduced, open if necessary. A fibrous union of a minimally displaced fractured medial epicondyle may result in lengthening and functional compromise of the medial collateral ligament. Chronic elbow instability is an unusual lesion. Repair of chronic elbow instability is best performed by restitution of medial collateral ligament function.
