Abstract:Abstract: [Objective] To evaluate the effect of arthroscopic FiberTape suture bridge fixation of the greater tuberosity fractures of the proximal humerus. [Methods] Between March 2019 and January 2021, 12 cases of greater tuberosity fractures of the proximal humerus were treated with arthroscopic FiberTape suture bridge fixation technique. 10 patients were followed up, including 8 males and 2 females, with an average age of 47.3 years (range from 22 to 59 years). The causes of injury were 4 cases of falling from height, 3 cases of traffic accident and 3 cases of military sports injury. There were 4 cases of left shoulder and 6 cases of right shoulder. [Results] The follow-up period ranged from 13 to 28 months (mean 18.5 months). The average operation time was 55-130 minutes, with an average of 78 minutes. There was no neurovascular injury, no infection and other complications. At the last follow-up, the mean American Shoulder and Elbow Surgeon score (ASES) was 89.3±3.2(range: 85-100), the mean Constant score was 93±4.6(range: 88-97), and the mean VAS pain score were 0.8 ±0.3 (range 0-1). Among 10 cases, 9 had anatomic reduction of fractures and 1 had slight displacement of fracture fragments with no re-operation. Bony healing was obtained in all cases. [Conclusion] The arthroscopic FiberTape suture bridge fixation technique was effective for the treatment of greater tuberosity fractures of the proximal humerus with less trauma, reliable fixation, no cutting of rotator cuff and no need for re-operative implant removal.
