Arthroscopic Reinsertion of Lateral Collateral Ligament, Anterior Capsular Plication, and Coronoid Tunneling Technique for Chronic Elbow Posterolateral Rotatory Instability

Abstract


Posterolateral rotatory instability (PLRI) of the elbow is a chronic condition that results from lateral collateral ligament complex injury and presents with pain, clicking, and subluxation within the flexion and extension arcs of elbow motion. The primary cause involves a lesion of the lateral collateral ligament complex and its avulsion from the lateral epicondyle. In most cases, it is the result of trauma such as a fall on an outstretched hand or any other mechanism that imparts axial compression, valgus force, and supination. Several surgical techniques have been described for the treatment of PLRI, but there is no consensus regarding the ideal surgical treatment. The advantages of an arthroscopic approach for the treatment of PLRI are first diagnostic. Arthroscopy allows for visualization and diagnosis of every compartment of the elbow. The main steps of the surgical procedure consist of reinsertion of the lateral collateral ligament, anterior capsular plication, and coronoid tunneling. By use of this technique, it is possible to perform an anatomic repair and provide stability of the elbow.
