Abstract
Objective: Exploring the therapeutic effect of implementing an improved needle insertion method in the treatment of proximal femoral nail anti-rotation (PFNA) internal fixation in patients with intertrochanteric fractures of the femur, and exploring the influencing factors of postoperative efficacy. Method: 100 patients with intertrochanteric fractures of the femur admitted to our hospital from January 2020 to December 2023 were randomly divided into two groups, both receiving PFNA internal fixation treatment. The control group received conventional method of inserting guide pins during surgery, while the study group received improved method of inserting guide pins. The efficacy, clinical indicators, and complications were compared between the two groups. Then, those with excellent and poor postoperative efficacy were included in the excellent group and the poor group, respectively. Univariate and multivariate logistic regression analyses were conducted on the factors that affect postoperative efficacy. Results: The proportion of age in the excellent group was generally younger than that in the poor group. The proportions of preoperative and postoperative complications and anemia in the excellent group were lower than those in the poor group. The proportion of early postoperative functional exercise in the excellent group was higher than that in the poor group. The proportion of improved needle insertion method in the excellent group was higher than that in the poor group (P < 0.05). After multiple logistic regression analysis, age, postoperative complications, preoperative complications, anemia, and intraoperative needle insertion method were risk factors affecting postoperative efficacy (P < 0.05). Conclusion: The implementation of improved needle insertion method in PFNA internal fixation treatment for patients with intertrochanteric fractures of the femur has a definite therapeutic effect and high safety. Age, preoperative complications and postoperative complications, anemia, and intraoperative needle insertion methods are risk factors that affect the therapeutic effect.
