Objective To compare the short-term clinical outcomes of three operation methods proximal humerus locking plate,anatomical mini-plate,and arthroscopic suture-bridge technique,for humerus greater tuberosity fractures.Methods The clinical outcomes of 1 year follow-up from 78 cases were enrolled.They were divided into three groups according to different surgical techniques:33 cases of utilizing proximal humerus locking plate group,24 cases of applying anatomical mini-plate group,and 21 cases of suture-bridge technique with arthroscopy group,in the treatment of humerus greater tuberosity fractures.Results All patients achieved satisfactory outcomes towards fracture reduction and healing.The incision length in the locking plate group was significantly longer than that in the mini-plate group and arthroscopy group,and the difference was statistically significant(P<0.01).There was no significant difference in the surgical time and fracture healing time among the three groups(P>0.05).At the one-year follow-up,the shoulder joint abduction and ASES score in the mini-plate group and arthroscopy group were significantly better than those in the locking plate group(P<0.01).There were 15 cases of post-operative complications,with 9 cases in the locking plate group,4 cases in the mini-plate group,and 2 case in the arthroscopy group.Conclusion All three surgical methods can achieve satisfactory fracture healing and functional recovery in the treatment of humerus greater tuberosity fractures.However,arthroscopic suture-bridge technique combined with cannulated screws is the preferred method for its minimally invasive,safe,and effective outcomes.
