【Abstract】 Objective To investigate the clinical effect of arthroscopic suture fixation for the treatment of the greater tuberosity fractures.Methods From July 2013 to December 2014, the application of bridge suture fixation for the treatment of greater tuberosity fractures in 20 cases of shoulder arthroscopy. The function of the shoulder joint was assessed by postoperative evaluation of Xray and CT reduction, American Shoulder and elbow surgeon score (ASES score), simple shoulder test score function (SST score) and shoulder joint function of University of California score (UCLA score). The clinical curative effect was evaluated with UCLA score.Results During an average followup of 115 months, 19 patients were followed up. All the 19 patients got anatomical reduction, and ASES score increased from 467±399 to918±232 (P＜005), SST score increased from 40±088 to 91±067 (P＜005), UCLA score increased from 156±259to 334±157 (P＜005). There were 13 cases and 6 cases with excellent UCLA score and good UCLA score.Conclusion Arthroscopic suture fixation for the greater tuberosity fractures is reliable.
