Objective: This study aims to evaluate the effectiveness of the anterior minimally invasive clamping technique in conjunction with a lower extremity axial bone traction device for treating irreducible intertrochanteric fractures. Methods: We conducted a retrospective analysis of data from 69 patients with irreducible intertrochanteric fractures who underwent limited open reduction and intramedullary nail fixation at our hospital between January 2022 and October 2023. All patients had subtrochanteric fractures of the femur. Patients received treatment using the anterior minimally invasive clamping technique combined with a lower extremity axial bone traction device for reduction (clamping + bone traction device group). The cohort included 27 males and 42 females with a mean age of (71.32±5.11) years (range, 60-83 years). Sixty-nine patients with irreducible intertrochanteric fractures were matched for gender and age in a 1:1 ratio. The 1:1 matching process was performed using a propensity score matching method to ensure comparability between the two groups. Key matching variables included comorbidities (hypertension, diabetes mellitus, coronary heart disease, and cerebrovascular disease), ...
