Abstract:
Objective To compare arthroscopic double-row bridging suture and minimally invasive locking plate system in the treatment of simple avulsion fracture of humeral greater tuberosity.Methods A retrospective study was conducted of the 93 patients with avulsion fracture of humeral greater tuberosity who had been treated at Orthopaedic Center,Beijing Luhe Hospital from January 2012 to December 2016.Of them,38 were treated by arthroscopic double-row bridging suture (ADRB) and 55 by open reduction and internal fixation with minimally invasive locking plate system (MIPS).Regular X-ray follow-ups were carried out at 3,6 and 12 months postoperatively and every 6 months afterwards.Surgical time,range of motion (ROM) of the shoulder,American Shoulder and Elbow Surgeons (ASES) score,Visual Analogue Scale (VAS) and complications were recorded preoperatively and at the last follow-up.Results The patients of the arthroscopy and plate groups were comparable because there were no significant differences in the preoperative general data between them (P ＞ 0.05).The average follow-up time for the 93 patients was 35.9months (from 12 to 60 months).The operation time for the arthroscopy group (97.0 ± 20.1 min) was significantly longer than that for the plate group (67.5 ± 19.0 min) (P ＜ 0.05).At the last follow-up,anteflexion lift (152.6° ± 12.9°),abduction lift (154.0° ± 13.5°) and internal rotation angle at 90° (57.7° ±12.2°) in the arthroscopy group were significantly better than those in the plate group (134.9° ± 17.8°,129.5° ± 18.6° and 50.8° ± 12.9°,respectively) (P ＜ 0.05).At the last follow-up,the ASES scores for the arthroscopy and plate groups were 88.5 ± 7.6 and 85.1 ± 11.3,respectively,showing no statistically significant difference (P ＞ 0.05);the VAS scores for the 2 groups were 1.5 ± 1.2 and 2.2 ± 1.5 respectively,showing a statistically significant difference between the 2 groups (P ＜ 0.05).There was no significant difference between the2 groups in improvement of ASES scores (P ＞ 0.05).Ninety fractures healed after 3 months while 3 fractures in the arthroscopy group did after 6 months.In the plate group,7 patients developed shoulder stiffness 3 to 6 months after surgery and 3 ones reported pain during abduction.Conclusions Both ADRB and MIPS are an effective treatment for simple avulsion fracture of humeral greater tuberosity.MIPS fixation needs shorter surgical time while ADRB leads to better postoperative shoulder ROM.
