Meta-analysis of locking plate combined with fibular allograft and locking plate alone in the treatment of proximal humeral fractures / 中国组织工程研究

ABSTRACT

BACKGROUND: The best treatment of proximal humeral fracture has always been controversial. Open reduction and internal fixation with locking plate is a common method for the treatment of proximal humeral fractures. In recent years, many studies have pointed out that locking plate combined with fibular allograft can obtain better rigid structure. OBJECTIVE: To evaluate the clinical efficacy of locking plate and locking plate combined with fibular allograft in the treatment of proximal humeral fractures. METHODS: CNKI, Wanfang database, VIP, PubMed, EMBASE, and Cochrane Library were searched for articles concerning locking plate and locking plate combined with fibular allograft for proximal humeral fractures published from inception to January 2020 for quality evaluation. International Cochrane collaboration RevMan 5.0 software was used for meta-analysis. The difference in American shoulder and elbow surgeons score, Constant score, humeral head height loss value, the change of humeral neck angle, incidence of postoperative complications, secondary surgery rate, screw cutout rate, and humeral head necrosis rate were compared between the locking plate group and locking plate combined with fibula group. RESULTS AND CONCLUSION: (1) Eight studies were included with a total of 623 patients. (2) Results analysis showed that there were significant differences between the locking plate group and locking plate combined with fibula group in American shoulder and elbow surgeons score (95%CI4.29-6.84, P 0.05) and humeral head necrosis rate(95%CI0.41-2.11, P > 0.05). (4) Locking plate combined with fibula with simple locking plate in American shoulder and elbow surgeons score, Constant score, humeral head height loss value, neck stem Angle values, the incidence of postoperative complications, and screw cutout rate has a better clinical effect, but does not have significant difference in the second operation rate or humeral head avascular necrosis..
