Meta-analysis of the effect of double endobutton and clavicular hook plate on the treatment of acromioclavicular dislocation / 中国组织工程研究

ABSTRACT

OBJECTIVE: Because the double Endobutton plate has more advantages than the clavicle hook plate in the treatment of acromioclavicular joint dislocation, and the trauma is small; it does not need to be removed through secondary surgery. Thus, it has been widely used in clinical practice in recent years. Meta-analysis was used to investigate whether there were differences in the treatment of acromioclavicular dislocation between double Endobutton plate and clavicle hook plate so as to provide effective guidance for clinical treatment. METHODS: The database Cochrane library, PubMed, EBSCO, CNKI, VIP and Wanfang were searched from the database inception to January 2020. All the literatures related to the treatment of acromioclavicular dislocation with double Endobutton plate and clavicle hook plate were collected. The literatures were selected according to the inclusion and exclusion criteria to extract the data and to carry out the relevant analysis. The literatures that meet the requirements were screened out. The quality of the selected relevant literatures was assessed. All outcome indicators were analyzed by RevMan 5.3 software. RESULTS: (1) A total of 38 articles were included, and the total number of cases was 2 199, of which 1 035 cases were in the double Endobutton plate group and 1 164 cases were in the clavicle hook plate group. (2) The results showed that the double Endobutton plate group was superior to the clavicle hook plate group in the excellent and good rate [RR=1.19, 95%CI(1.13, 1.26), P < 0.000 01], operation time [MD=10.54, 95% CI(6.09, 15.00), P < 0.000 01], intraoperative blood loss [MD=-14.83, 95%CI(-20.54,-9.13), P < 0.000 01], hospitalization time [MD=-1.44, 95%CI(-2.65,-0.23), P=0.02], incision length [MD=-2.87, 95%CI (-3.60, -2.14), P < 0.000 01], hospitalization cost [MD=-2 442.10, 95% CI(-4 466.34, -417.86), P=0.02], shoulder pain after operation [RR=0.34, 95%CI(0.22, 0.53), P < 0.000 01], visual analogue scale score [MD=-0.85, 95% CI(-1.28, -0.41), P=0.000 2], final Constant-Murley score at 6 months postoperatively [MD=8.82, 95%CI(1.91, 15.72), P=0.01; MD=6.66, 95%CI(4.46, 8.86), P < 0.000 01]CONCLUSION: The treatment of Rockwood III type and above acromioclavicular joint dislocation with double Endobutton plate is superior to that clavicular hook plate. It has the advantages of short operation time, less intraoperative blood loss, less trauma, short hospitalization time and less cost, and good functional recovery of shoulder joint after operation.
