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.

Project description:PurposeThe purpose of the study is to describe the functional and structural outcomes of the arthroscopic 4-strand, knotless, double-row construct with suture tapes for the surgical treatment of displaced and/or comminuted greater tuberosity fractures of the humerus.MethodsPatients were enrolled between December 2012 and January 2018. The main inclusion criteria were a comminuted and/or displaced tuberosity fracture with a displacement of at least 5 mm in any plane fixed under arthroscopy using a 4-strand, knotless, double-row construct. The technique involves reducing the displaced fragment with 2 medially placed, transtendinous anchors and compressing the greater tuberosity using the tapes from these medial anchors in 2 laterally placed anchors. The exclusion criteria were a fracture that was more than 10 days old at the time of surgery or a history of shoulder surgery and 3- or 4-part fractures. The postoperative rehabilitation protocol was similar for all patients. Constant scores, Quick Dash, return to work and sport, and complications were reported after a minimum follow-up period of 24 months. Bone healing was systematically evaluated on standardized radiographs, including lateral scapula view and anteroposterior views.ResultsTwenty-one patients were enrolled in this study. One patient did not complete the follow-up examination period and thus was excluded, leaving 20 patients in this study. At a median (SD) follow-up of 32 (9) months, the median (SD) Constant score was 94.7 (7.3) points, the median (SD) Quick Dash was 1.7 (4) points, and median (SD) visual analog scale score was 0.5 (1.4). All patients returned to previous work and sport level. No malunions or nonunions were seen. One conversion to open surgery was required for failure of the lateral row during surgery in a 62-year-old woman with osteopenic bone. Two patients experienced complex regional pain syndrome in the postoperative period that resolved after nonoperative treatment.ConclusionsIn this series, the use of arthroscopy combined with the biomechanical properties of knotless double-row constructs contributed to postoperative satisfactory functional results and healing of greater tuberosity fracture. In addition, range of motion was early, and no hardware removal was required. However, care should be taken with osteopenic bone where anchorage can fail.Level of evidenceLevel IV, case series.
