Arthroscopic Laminar Spreader for Rotator Cuff Repair

Abstract

Arthroscopic rotator cuff repair can be challenging and requires adequate visualization and space. However, the narrow subacromial space can make difficult to perform tendon release and repair under arthroscopy. Inadequate visualization may lead to inaccurate suture placement, compromising the reduction and fixation of the repaired rotator cuff tendons. Manual or mechanical distraction (using an arm positioner) can be used to increase the working space. However, consistent distraction is very difficult to maintain manually over time due to fatigue, whereas mechanical distraction may overstretch the brachial plexus. To overcome these difficulties, we describe a technique using a specific laminar spreader for subacromial distraction during arthroscopic rotator cuff repair. The arthroscopic laminar spreader, inserted into the subacromial space, is used to distract the humeral head inferiorly from the acromion, improving subacromial space visualization and enabling easily rotator cuff release and repair. The shoulder distraction device improves the surgeon’s performance without surgical assistance and allows reducing the operative time with safety. It can be also used anteriorly (to repair the subscapularis) or posteriorly (to repair the infraspinatus and teres minor) or to perform other procedures like superior capsular reconstruction or additional patch.
