Abstract:
OBJECTIVE:To compare the clinical efficacy of locking plate fixation with a fibular strut allograft (FA group) and locking plate fixation alone (LP group) in the treatment of proximal humeral fractures in adults by Meta-analysis.
METHODS:Databases including PubMed, The Cochrane Library, Embase, Chinese BioMedical Literature Database(CBM), China National Knowledge Infrastructure(CNKI), WanFang Data, and China Science and Technology Journal Database (cpvip Database) were searched by computer from establishing to March 2020 to collect studies about locking plate fixation with fibular strut allograft versus locking plate fixation alone for proximal humeral fractures in adults. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. The postoperative humeral head height changes, neck-shaft angle changes, Constant-Murley score, American Shoulder and Elbow Surgeons(ASES)score, visual analogue scale(VAS), varus malunion rate, and screw penetration rate were compared by RevMan 5.3 software for Meta-analysis.
RESULTS:Ten cohort studies were enrolled in a total of 749 patients, 300 patients in the FA group and 449 patients in the LP group. The results of Meta-analysis showed that locking plate with fibular strut allograft was superior to locking plate fixation alone in the changes in humeral head height [MD=-2.69, 95%CI(-3.24, -2.13), P<0.000 01], the changes in neck-shaft angle [MD=-5.65, 95%CI(-7.18, -4.12), P<0.000 01], Constant-Murley score [MD=9.00, 95%CI(4.26, 13.73), P=0.000 2], the ASES score [MD=5.56, 95%CI(4.29, 6.84), P=0.000 01], VAS score [MD=-0.23, 95%CI(-0.37, -0.09), P=0.001], the varus malunion rate [RR=0.22, 95%CI(0.09, 0.53), P=0.000 7] and the screw penetration rate [RR=0.26, 95%CI(0.13, 0.55), P=0.000 3], respectively.While there was no significant difference in the rate of osteonecrosis of the humeral head [RR=1.18, 95%CI(0.57, 2.45), P=0.65].
CONCLUSION:For proximal humeral fractures in adults, current evidence shows that locking plate fixation with fibular strut allograft is superior to single locking plate fixation in improving postoperative radiological outcomes and shoulder function, relieving postoperative pain, reducing varus malunion rate and screw penetration rate. However, the efficacy in decreasing the osteonecrosis rate is not clear. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.
