Effect of PFNA Combined with Reconstruction Plate on Bone Metabolism and Hip Function in Patients with A3 Type Intertrochanteric Fracture of Femur
Objective:To investigate the effects of proximal femoral nail anti-rotation(PFNA)combined with reconstruction plate on bone metabolism and hip function in patients with A3 type intertrochanteric fracture of femur.Methods:The clinical data of 60 patients with A3 intertrochanteric fracture of femur admitted in Guangzhou Zengcheng District Shitan Town Center Health Center from January 2021 to June 2023 were retrospectively analyzed,and they were divided into a control group and a study group according to different surgical protocols,with 30 cases in each group.The control group was treated with PFNA,and the study group was treated with PFNA combined with reconstruction plate.The bone metabolism,hip function and complications of the two groups were compared before and after surgery.Results:One and three months after operation,the contents of amino terminal propeptide and β-collagen degradation products of type 1 procollagen in the study group were lower than those in the control group,and the contents of molecular fragments in the N terminal of calcin and bone-specific alkaline phosphatase in the study group were higher than those in the control group,with statistical significance(P<0.05).At 1 and 3 months after surgery,the Harris scores of hip joint in the study group were higher than those in the control group,with statistical significance(P<0.05).After operation,the complication rate of the study group was lower than 26.67%of the control group,the difference was statistically significant(P<0.05).Conclusion:The application of PFNA combined with reconstruction plate in the treatment of patients with A3 intertrochanteric fracture of femur can effectively improve bone metabolism indexes and hip joint function,with high safety.
