Yamamoto N, Tomita Y, Noda T, et al. - This study was undertaken to investigate the relationship between bone-implant stability factors, including nail construct, and the rate of reoperation in a more extensive case series with comprehensive variables. Researchers designed a retrospective cohort study including a total of 390 patients with trochanteric fractures aged ≥ 60 years and treated with intramedullary nailing. The primary endpoint included the rate of reoperation due to any cause. Factors associated with reoperation were distinguished by using univariate and multivariable logistic regression analyses. It was shown that the risk factors on bone-implant stability for reoperation were the reduction quality and fracture type. Regarding the intraoperative decision-making process, when the intramedullary reduction has been maintained intraoperatively, the selection of a nail length with an FR > 0.8 is a better option.
