PurposeThis study aimed to investigate the long-term outcomes of patients with a femoral neck fracture (FNF), treated with the Dynamic Locking Blade Plate (DLBP).MethodsRetrospective analysis of prospectively collected data of a multicentre cohort of patients with FNFs was conducted, regarding the long-term incidence of revision surgery after DLBP. Implant failure was evaluated using Kaplan-Meier and Cox regression analysis. Secondary outcomes were the indication for revision surgery, complications, time to revision surgery, rate of elective removal of the implant, potential predictors for revision surgery and mortality.ResultsMedian follow-up of 389 included patients was 98 months; 20.6% underwent revision surgery; 28.8% after treatment of a displaced FNF (dFNF) and 10.0% with a undisplaced FNF (uFNF). 5.7% (n = 22) of the patients had operation related complications and 32.9% (n = 128) deceased during follow-up. Median time to revision surgery was 13 (dFNF) and 18 months (uFNF). 15.7% of the DLBPs were electively removed. In the multivariate Cox regression analysis, female gender (hazard ratio 2.1, 95% CI 1.2-3.7) and a TAD > 25 mm (hazard ratio 2.9, 95% CI 1.7-5) were significant predictors for revision surgery in patients with dFNF.ConclusionThis study is the first long-term follow-up study on the outcome of the DLBP. The DLBP demonstrated positive long-term results in the treatment of FNF.© 2024. The Author(s).
