ObjectiveTo explore the relevant factors affecting the efficacy of surgery for intertrochanteric fracture.MethodsA retrospective case series study was conducted to analyze the clinical data of 212 patients with intertrochanteric fractures from January 2021 to December 2023. The patients, comprising 100 males and 112 females aged 65–98 years old (mean age 77.8 ± 10.5 years), were categorized based on fracture healing outcomes into a normal healing group (163 cases) and an abnormal healing group (49 cases, including 2 cases of non-union). Factors such as gender, age, injury side, fracture classification, thickness of femoral lateral wall, medial support, tip-apex distance and fixation position were recorded and analyzed through Logistic regression to identify the main factors influencing fracture healing.ResultsUnivariate analysis revealed statistically significant differences in AO classification, Evans-Jensen classification, medial support, tip-apex distance and main screw position between the two groups (P
