股骨颈动力交叉固定系统与全髋关节置换术治疗股骨颈骨折的疗效比较

Comparison of curative effect of femoral neck dynamic cross fixation system(FNS)and total hip replacement in the treatment for femoral neck fracture

目的对比股骨颈动力交叉固定系统(FNS)与全髋关节置换术治疗股骨颈骨折的疗效。方法回顾性分析2020年1月至2022年10月收住的128例股骨颈骨折病人的临床资料,均为GardenⅢ型,选取采用全髋关节置换术的20例纳入全髋关节置换组,选取采用FNS治疗的20例纳入FNS组。记录2组骨折复位的质量、手术时间、术中出血、骨折愈合时间、术后并发症发生率,并在术后3个月随访时进行疼痛VAS评分以及髋关节功能Harris评分的评估。结果2组疼痛VAS评分以及髋关节功能Harris评分差异均无统计学意义(P>0.05)。FNS组手术时间以及出血量明显低于全髋关节置换组(P<0.01)。结论与全髋关节置换相比,FNS具有手术创伤小、手术时间短、手术出血量少的优势。

Objective To compare the efficacy of femoral neck dynamic cross fixation system(FNS)and total hip arthroplasty in the treatment of femoral neck fracture.Methods A retrospective analysis was performed on the clinical data of 128 elderly patients with femoral neck fracture admitted to the Second Affiliated Hospital of Nanjing Medical University from January 2020 to October 2022.Among them,20 cases were treated with total hip arthroplasty and 20 cases were treated with FNS.All cases were GardenⅢtype.The quality of fracture reduction,operation time,intraoperative bleeding,fracture healing time and incidence of postoperative complications were recorded,and visual analogue scale(VAS)for pain perception and Harris hip joint function score were evaluated three months later.Results There were no statistical differences in VAS score and Harris score of hip joint function between the two groups(P>0.05).The operation time and bleeding volume in the FNS group were significantly lower than those in the total joint replacement group(P<0.01).Conclusions Compared with total hip replacement,FNS shows the advantages of less trauma,shorter operation time and less blood loss.
