Stem-Based Repair of the Subscapularis in Total Shoulder Arthroplasty

Subscapularis integrity following total shoulder arthroplasty (TSA) is important to maintaining glenohumeral joint stability and functional outcome. In recent years increased emphasis has been placed on the management of the subscapularis during TSA. Options for management of the subscapularis during TSA include tenotomy, release of the tendon from the bone (peel technique), or a lesser tuberosity osteotomy (LTO). Several studies have demonstrated that subscapularis integrity is often impaired with a traditional tenotomy approach.1,2 Based on these studies, a subscapularis peel or LTO approach have gained popularity.3 This technical article describes a subscapularis peel repair technique that is integrated into a press-fit anatomical short-stem during TSA.
