Proximal femoral nail anti-rotation and dynamic hip screw in repair of intertrochanteric fracture in the elderly：a meta-analysis / 中国组织工程研究

ABSTRACT

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.
