股骨颈动力交叉钉系统治疗股骨颈骨折临床分析

Clinical Analysis of Femoral Neck Fracture Treated with Femoral Neck System

摘要: 目的：分析股骨颈动力交叉钉系统(Femoral Neck System, FNS)治疗股骨颈骨折的临床疗效。方法：回顾性分析2020年5月至2022年1月我院收治的46例股骨颈骨折患者的临床资料，统计患者年龄，手术时间、术中出血量、术后住院时间、术后采用Garden指数评定骨折复位质量；随访记录骨折愈合时间及末次随访记录髋关节功能Harris评分评定髋关节功能恢复情况。结果：46例股骨颈骨折患者均采用FNS闭合复位内固定，患者平均年龄48.5岁，平均手术时间87分钟，平均出血量85.9 ml。住院时间4~17天，平均9.9天。术后骨折复位质量Garden指数均在二级及以上，术后随访10~30个月，平均16.9个月。随访期间未发现感染、内固定松动、内固定断裂、股骨头缺血性坏死等并发症，有8例发生股骨颈短缩，但患者未出现不适及髋关节功能未受明显影响，骨折愈合时间为3~6个月，平均4.6个月。按Harris髋关节功能评分，本组髋关节功能优38例，良8例，优良率100%。结论：股骨颈骨折是髋部常见的骨折类型，采用FNS治疗股骨颈骨折，操作简单，手术安全，创伤小，固定牢固，术后可早期下床活动，疗效满意。

Abstract: Objective: To analyze the clinical efficacy of the Femoral Neck System (FNS) in the treatment of femoral neck fractures. Methods: The clinical data of 46 patients with femoral neck fractures ad-mitted to our hospital from May 2020 to January 2022 were retrospectively analyzed, and the pa-tients’ age, operation time, intraoperative bleeding, postoperative hospital stay, and postoperative quality of fracture repositioning using the Garden index were counted; the fracture healing time and hip function Harris score at the last follow-up were recorded to assess the recovery of hip func-tion. Results: All 46 patients with femoral neck fractures were fixed internally with FNS closed re-duction, the mean age of the patients was 48.5 years, the mean operative time was 87 minutes, and the mean bleeding was 85.9 ml. The hospital stay was 4~17 days, with a mean of 9.9 days. The postoperative quality of the fracture reduction Garden index was grade II or above, 10~30 months of postoperative follow-up, with a mean of 16.9 months. No complications such as infection, internal fixation loosening, internal fixation fracture, or ischemic necrosis of the femoral head were found during the follow-up period. Shortening of the femoral neck occurred in 8 cases, but the patients did not experience discomfort and hip function was not significantly affected, and the fracture healing time was 3~6 months, with an average of 4.6 months. According to the Harris hip function score, the hip function of this group was excellent in 38 cases and good in 8 cases, with an excellent rate of 100%. Conclusion: Femoral neck fracture is a common type of fracture in the hip, and the treatment of femoral neck fracture by FNS is simple, safe, less traumatic, firmly fixed, and can be early out of bed after surgery, with satisfactory results.
