股骨近端仿生髓内钉与二代股骨近端抗旋髓内钉治疗老年不稳定型股骨粗隆间骨折的效果比较OA

Objective:To compare the clinical application effects of proximal femoral bionic nail(PFBN)and proximal femoral nail antirotation-Ⅱ(PFNA-Ⅱ)in the treatment of unstable intertrochanteric femoral fractures in the elderly.Method:Sixty-eight elderly patients with unstable intertrochanteric femoral fractures who visited Gongqingcheng People's Hospital from November 2024 to May 2025 were included.They were divided into two groups using a random number table method,with 34 cases in each group.The control group underwent fixation with PFNA-Ⅱ,while the observation group underwent fixation with PFBN.The perioperative indicators,postoperative recovery indicators,Harris scores and VAS scores 1,3,and 6 months after surgery,Barthel index and Holden walking ability grading 6 months after surgery,as well as the incidence of postoperative complications were compared between the two groups.Result:The intraoperative blood loss and the number of fluoroscopy of the observation group were more than those of the control group,the operation time was longer than that of the control group(P<0.05).There were no statistically significant differences in VAS scores 1 and 6 months after surgery,hospital stay,and fracture healing time between the two groups(P>0.05).The time for the first walking after surgery and the time for full weight-bearing in the observation group were earlier than those in the control group(P<0.05).The VAS score of the observation group 3 months after surgery was lower than that of the control group,and the Harris scores 1,3,and 6 months after surgery were higher than those of the control group(P<0.05).At 6 months after surgery,the Barthel index and Holden walking ability grading scores of the observation group were higher than those of the control group(P<0.05).The total incidence of postoperative complications in the observation group(5.9％)was not statistically different from that in the control group(17.6％)(P>0.05).Conclusion:PFBN can effectively accelerate the early weight-bearing of elderly patients with unstable intertrochanteric femoral fractures after surgery,promote functional recovery,and significantly improve hip joint function and daily living ability.
