Abstract
Femoral shaft fractures are commonly treated with intramedullary nailing, but delayed union remains a concern and nail dynamization is a simple procedure that promotes fracture healing by improving the mechanical environment. This prospective observational study was conducted at NITOR, Dhaka, Bangladesh from March 2019 to August 2019 and March 2022 to March 2024, including 24 patients with delayed union following intramedullary nailing for femoral diaphyseal fractures who underwent dynamization. Data on age, sex, smoking status, fracture type (AO classification) and reduction method were analyzed; the mean age was 29.6±8.9 years, 87% were male, 37.5% were smokers, 62.5% were nonsmokers, fracture types included 37.5% AO 32A and 62.5% AO 32B and open and closed reduction were performed in 62.5% and 37.5% of patients, respectively. Smoking was identified as a significant predictor of non-union after femoral nail dynamization, while fracture characteristics, including AO fracture type and reduction method, also influenced fracture union. Thus, data shows that smoking and fracture characteristics should be considered when predicting fracture healing after femoral nail dynamization.
