The effect of cerclage wiring with intramedullary nail surgery in proximal femoral fracture: a systematic review and meta-analysis.

Abstract

The aim of this study was to evaluate the utility of cerclage wiring with intramedullary nail surgery in the treatment of proximal femoral fractures. MEDLINE, Embase, and Cochrane Library were systematically searched for studies that evaluated the impact of cerclage wiring on proximal femoral fractures published up to September 20, 2021. Pooled analysis identified differences in the (1) fracture healing profile, (2) perioperative variables, (3) complications, and (4) clinical outcome score between cerclage wiring and non-cerclage wiring. Fourteen studies involving 1,718 patients with proximal femoral fractures who underwent cephalomedullary nailing surgeries were included. The pooled analysis revealed a longer fracture union time in the non-cerclage wiring group than in the cerclage wiring group (mean difference [MD] = - 1.03months; 95% confidence interval [CI]: - 1.47 to - 0.59; P < 0.001), and there was no difference in the nonunion rate. The operation time was longer in the cerclage wiring group (MD = 14.32min; 95% CI: 6.42-22.22; P < 0.001), but there were no differences in blood loss and the rate of poor quality of reduction. Superficial and deep infection rates showed no difference between the groups, and the readmission rate also showed no difference. The cerclage wiring group had a higher Harris hip score than the non-cerclage wiring group (MD = 2.13; 95% CI: 0.77-3.49; P = 0.002). Intramedullary nailing with cerclage wiring is considered a useful treatment method for proximal femoral fractures. It enables anatomic reduction and stable fixation, thereby reducing union time and facilitating rapid functional recovery.
