Arthroscopic Tri-anchor Double-Pulley Suture-Bridge Reduction of Greater Tuberosity Fracture

Abstract

Currently, cannulated screws, plates, and suture bridges are widely applied in the treatment of greater tuberosity fracture; however, further fragmentation of the fracture, risk of loss of fracture reduction, implant impingement, and anchor pullout are the drawbacks. Therefore, we present a pragmatic surgical technique called the arthroscopic tri-anchor double-pulley suture-bridge technique that uses a double-loaded metallic anchor as a lateral-row anchor. In the treatment of greater tuberosity fracture, this hybrid repair including 4 sets of double-pulley suture bridges and 2 sets of single rows can obtain powerful stiffness of the suture construct, the metallic anchor used as a lateral-row anchor can significantly reduce the risk of anchor pullout, the single-row process can lessen the overall surgical time, and implant impingement will not occur postoperatively.
