Arthroscopic Preparation 0f the Posterior and Posteroinferior Glenoid Labrum
Abstract
Arthroscopic repair of a glenoid labral tear is a common procedure and in certain cases of traumatic shoulder instability, a tear of the posterior or posteroinferior labrum is encountered. Although a number of portals have been described that provide excellent access to place anchors and perform the capsulolabral repair, preparation of the posterior, and posteroinferior glenoid- labral interface may be difficult. Classically. this portion of the labrum has been prepared using a direct posterior or accessory posterolateral portal. However, these portals usually provide an unfavorable trajectory that makes insertion of an arthroscopic labral preparation instrument into the chondrolabral junction difficult. This is due to the lack of co-linearity of the cannula relative to the posterior glenoid and labrum. Because of this trajectory, the labrum may be truncated or inadvertently torn if the posterior and posteroinferior labrum preparation is performed from these portals. This article describes a technique that allows easy access into the chondrolabral junction of this area of the glenoid labrum, without causing damage to the circumferential fibers of the labral tissue.
