HOW SHOULD THE SUBSCAPULARIS BE REPAIRED FOLLOWING SHOULDER ARTHROPLASTY?
F. Lam; D.N. Bhatia; K. van Rooyen; D. du Toit; and J.F. de Beer Cape Shoulder Institute, Cape Town, South Africa Introduction: We have devised a new technique of lesser tuberosity osteotomy with double row fixation of the subscapularis using suture anchors. Aim: To evaluate the biomechanical properties of this novel technique against two established methods of subscapularis repair including tendon to tendon and transosseous repairs. Method: Matched pairs of human cadaveric shoulders were allocated into 3 groups. Group 1 consisted of the double row technique with incision of the subscapularis along the bicipital groove with a lesser tuberosity osteotomy. A double loaded suture anchor was placed along the medial border of the osteotomy site and sutures were passed through subscapularis medial to the bone island in a horizontal mattress manner. A second anchor was inserted along the lateral border of the osteotomy site and the two sutures were tied onto the subscapularis holding sutures.
