Advantages and disadvantages of internal fixation with suture anchors and locking plate in the treatment of the greater tuberosity fracture / 中国组织工程研究

ABSTRACT

BACKGROUND: Open reduction and internal fixation with locking plate is wildly used in treatment of the greater tuberosity fracture, but certain disadvantages still existed. OBJECTIVE: To compare the effects of open reduction and internal fixation with suture anchors and locking plate in the treatment of the greater tuberosity fracture. METHODS: A retrospective review of 33 patients with greater tuberosity fracture treated with open reduction and internal fixation between January 2016 and December 2018 was conducted. According to internal fixation method, the patients were divided into anchor group (n=7) and plate group (n=26), which received open reduction + suture anchor fixation and open reduction + locking plate fixation. Operation time, incision length, intraoperative blood loss, postoperative displacement of fracture mass, and Constant-Murley score 1 and 3 months after surgery and in final follow-up were compared between the two groups. Adverse reactions were recorded in the two groups. RESULTS AND CONCLUSION: (1) Operation time was shorter in the anchor group (73.1±10.5 minutes) than in the plate group (98.2±11.9 minutes). Incision length was shorter in the anchor group (7.3±1.1 cm) than in the plate group (14.9±1.7 cm). Intraoperative blood loss was less in the anchor group (45.0±7.1 mL) than in the plate group (141.0±25.9 mL) (P 0.05). (4) All results suggest that compared with locking plate fixation, suture anchor fixation is easier to be operated with small trauma in the treatment of the greater tuberosity fracture.
