Is the traction table necessary to treat femoral fractures with intramedullary nailing? A meta-analysis.

ABSTRACT

BACKGROUND: The traction table is generally used in femoral intramedullary nailing surgery. Recently, some published studies have shown that the same or better treatment effects can be gotten without a traction table. It remains no consensus on this issue. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline was applied in this study. We searched PubMed, Embase, Web of Science, and Cochrane Library databases for eligible studies. The random-effect model was used to calculate the standardized mean difference (SMD) and risk ratios with 95% CIs. Trial sequential analysis (TSA) was performed to verify the results. RESULTS: The pooled estimates of seven studies, including 266 cases each in the manual traction group and traction table group, indicated that manual traction could shorten operative time [SMD, - 0.77; 95% CI (- 0.98, - 0.55); P < 0.00001] and preoperative set-up time [SMD, - 2.37; 95% CI (- 3.90, - 0.84); P = 0.002], but it would not reduce intraoperative blood loss volume and fluoroscopy time. No statistical difference was found in their fracture healing time, postoperative Harris scores, and malunion rate. The use of a Traction repositor could reduce the set-up time [SMD, - 2.48; 95% CI (- 4.91, - 0.05); P < 0.00001]. CONCLUSIONS: Compared with manual traction, the traction table in femoral intramedullary nailing surgery lengthened operative time and preoperative set-up time. At the same time, it did not show significant advantages in reducing blood loss volume and fluoroscopy time, or improving prognosis. In clinical practice, the optimal surgical plan must be made on a case-by-case basis to avoid unnecessary traction table use.
