Arthroscopic Reduction and Suture Bridge Fixation of a Large Displaced Greater Tuberosity Fracture of the Humerus.


ABSTRACT: Arthroscopic fixation of a greater tuberosity (GT) avulsion fracture by suture bridge repair has been described in several articles. However, all of them have used arthroscopic fixation of a small sized GT fracture fragment or have not used purely arthroscopic techniques. In this Technical Note, the authors describe another technique for large displaced GT fracture fixation by arthroscopy only, without any metal fixation. Standard anterior, posterior, lateral, and posterolateral viewing portals are established with an accessory portal for suture anchor insertion. During intra-articular examination, an anteroinferior capsulolabral tear, upper one-third subscapularis tendon tear, and posterosuperior displaced bony fragment are detected. A subscapularis tendon was repaired by a single-row technique. After repair, medial row anchors are inserted into the bare area of infraspinatus tendon and the posterior edge of supraspinatus tendon. A 1-PDS suture is used to pass strands of fiberwire. As with the remplissage procedure, the fiberwire was passed with an 18-gauge needle. Following the acromioplasty, the medial row tightening was done by reducing the fracture fragment. After that, the lateral row anchor was inserted into the bicipital groove, completing the suture bridge technique. This technique can effectively treat other pathologies, has less radiation hazard, and results in fewer soft tissue injuries.
