BACKGROUND:At present, a large number of studies have confirmed that reconstruction plate compared to Kirschner wire in the treatment of clavicular fracture showed good effects, but there is no precise report on the specific advantages at present. Clinical randomized controled study is less, and lacks of systematic evaluation. OBJECTIVE:To systematicaly evaluate the efficacy and safety of the treatment of the clavicle fractures with the reconstruction plate and the Kirschner wire by using a meta-analysis. METHODS: We retrieved the MEDLINE, Embase, PubMed, Cochrane library, CNKI, Wanfang database and VIP database from 2008 to 2015 by computer to colect al controled study relevant to reconstruction plate and Kirschner wire in the treatment of clavicle fracture, and screened the literatures that met the inclusion criteria. Al literatures were analyzed in strict quality evaluation. Excelent rate, delayed healing of incision, malunion, postoperative infection, loosening of internal fixation, postoperative fracture displacement, operation time, intraoperative bleeding volume and fracture healing time were selected as the evaluation indexes of a meta-analysis. Meta-analysis was performed with RevMan 5.2 software from the Cochrane Colaboration. RESULTS AND CONCLUSION:Finaly 12 Chinese articles published from 2008 to 2014 were included, with 911 patients. Meta-analysis results showed that compared with Kirschner wire, the reconstruction plate has a certain advantage in improving the excelent and good rate, shortening the delayed wound healing and reducing deformity healing, reducing postoperative infection, preventing the loosening of internal fixation and avoiding postoperative fracture displacement. However, the two surgical methods in the treatment of clavicular fracture were not significant in operation time, intraoperative blood loss and fracture healing time. These results suggest that compared with the Kirschner wire, reconstruction plate fixation for treatment of clavicular fracture had better curative effect. The reconstruction plate can be firstly selected in the permit of patient economic conditions and hospital conditions. Due to the limited sample size in this study, the multicenter, large-sample and long-term clinical randomized controled studies with more strict design are needed to increase the reliability of the evidence.

BACKGROUND:Now a lot of studies have confirmed that in contrast with the dynamic hip screw, the proximal femoral nail anti-rotation has a better therapeutic effect on the treatment of intertrochanteric fractures in the elderly, but there is no definite conclusion on the specific superiority at present. OBJECTIVE:To compare the curative effects of proximal femoral nail anti-rotation and dynamic hip screw in repair of intertrochanteric fracture using a meta-analysis. METHODS: We searched VIP database, Wanfang database, PubMed database and Embase database from 2011 to 2015, and colected randomized controled trials on proximal femoral nail anti-rotation and dynamic hip screw in repair of intertrochanteric fracture. Operation time, intraoperative blood loss, hospital stays, fracture healing time, Harris score, length of incision, bed time walking after the operation were used as evaluation indexes of meta analysis. Data were analyzed using RevMan 5.3 software. RESULTS AND CONCLUSION:In the end, we used 9 literatures, which contained 858 patients of intertrochanteric fractures in the elderly. The time of publication was from 2011 to 2015, and al of them were published in Chinese. The results of Meta-analysis showed that, compared with dynamic hip screw, proximal femoral nail anti-rotation in the treatment of intertrochanteric fractures in the elderly could effectively reduce operation time, blood loss, hospital stays, fracture healing time, length of incision and the time of walking after the operation was earlier, and it could obtain better recovery of hip function. We can point out that compared with dynamic hip screw, proximal femoral nail anti-rotation has certain advantages in the treatment of intertrochanteric fractures in the elderly. In some conditions, the patients and the hospitals can give priority to choose the proximal femoral nail anti-rotation in the treatment of intertrochanteric fractures in the elderly.
