Abstract：Objective:To compare the efficacy of effects of minimally invasive locking plate internal fixation and open reduction and internal fixation in the treatment of proximal humeral fractures. Method:A total of 66 patients with proximal humeral fractures who treated in Suzhou Ninth People's Hospital from December 2020 to January 2023 were selected as the study objects by random sampling method,and they were randomly divided into the conventional group and the study group,with 33 cases in each group. The conventional group was given open reduction and internal fixation,and the study group was given minimally invasive locking plate internal fixation,the clinical efficacy,complications,operation-related indicators,shoulder joint function and postoperative pain were compared between two groups. Result:The excellent and good rate of the study group was higher than that of the conventional group,the incidence of complications was lower than that of the conventional group,the intraoperative blood loss and drainage volume were less than those of the conventional group,the hospitalization time,operation time,incision length and fracture healing time were shorter than those of the conventional group,the postoperative shoulder pain,daily activities,range of activities,strength scores and total score were higher than those of the conventional group,and the visual analogue scale (VAS) scores at 1 d,3 d and 7 d after operation were lower than those of the conventional group,the differences were statistically significant (P<0.05). Conclusion:Compared with open reduction and internal fixation,minimally invasive locking plate internal fixation has a significant effect in the treatment of patients with proximal humeral fractures,reduce complications,improve surgery-related indicators and shoulder joint function,and reduce postoperative pain.
