External fixation versus intramedullary nailing for the management of open tibial fracture: meta-analysis of randomized controlled trials.
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2024;12(15):60 Int Orthop . 2023 Dec;47(12):3077-3097.What this means for my practice?
Overall, unreamed tibial intramedullary nailing (UTN) generally offers better outcomes in terms of reduced superficial infections and malunion rates compared to external fixation (EF) in the treatment of open tibial fractures. These results suggest a potential preference for UTN in clinical practice. However, careful postoperative management is essential to prevent hardware failure. The main limitation of this paper is the potential variability in the surgical expertise and methods applied across different studies, which might influence the results.
Study Summary
Six randomized controlled trials including 407 patients with open tibial fractures were included in this systematic review and meta-analysis comparing external fixation (EF) versus unreamed tibial intramedullary nailing (UTN). Pooled outcomes of interest included postoperative superficial and deep infections, malunion, delayed union, nonunion, and hardware failure. UTN significantly reduced the rates of superficial infection and malunion compared to EF, while both treatments showed similar effectiveness for deep infections, delayed union, and nonunion. EF, however, resulted in fewer hardware failures. This analysis suggests that UTN might be preferred for managing open tibial fractures, with careful monitoring of postoperative weight-bearing to prevent hardware failure.
Why was this study needed now?
Open tibial fractures are common and complex injuries often resulting from high-energy trauma, posing significant challenges in management due to poor soft tissue coverage and blood supply issues leading to complications such as infection and poor bone healing. Both EF and UTN are widely used, but debate continues over the optimal treatment approach. This study is essential now to address gaps in the existing literature by rigorously comparing EF and UTN through a meta-analysis of high-quality randomized controlled trials, aiming to refine treatment recommendations based on up-to-date evidence.
What was the principal research question?
In patients with open tibial fractures, is unreamed tibial intramedullary nailing compared to external fixation more effective in reducing the incidence of complications?
