【摘要】 目的 分析比较Gamma 3钉和抗旋型股骨近端髓内钉治疗老年不稳定型股骨粗隆间骨折的临床疗效。方法 回顾性选取2018年1月—2019年8月滕州市中心人民医院收治的96例老年不稳定型股骨粗隆间骨折患者的临床资料，根据手术方式的不同将其分为两组，PFNA组采用抗旋型股骨近端髓内钉（proximal femoral nail antirotation, PFNA）治疗，Gamma 3组采用Gamma 3钉治疗。每组48例。比较两组患者围术期指标，Harris评分和并发症发生情况。结果 PFNA组手术时间、切口长度及住院时间均短于Gamma 3组，差异有统计学意义（P<0.05）；两组下地负重时间和骨愈合时间比较，差异无统计学意义（P>0.05）。Gamma 3组优良率（85.41%）与PFNA组（87.50%）比较，差异无统计学意义（P>0.05）。Gamma 3组和PFNA组并发症发生率分别为14.58%和6.25%，差异无统计学意义（P>0.05）。结论 Gamma 3钉和抗旋型股骨近端髓内钉治疗老年不稳定型股骨粗隆间骨折疗效相当，但PFNA具有切口创伤小，恢复较快，预后并发症情况更优的特点。更多还原

【Abstract】 Objective To analyze and compare the clinical efficacy of Gamma3 nail and antirotation proximal femoral nail in the treatment of unstable intertrochanteric fracture of senile femur. Methods A total of 96 elderly patients with unstable intertrochanteric fracture of femur admitted to Tengzhou Central People’s Hospital from January 2018 to August 2019 were retrospective selected of clinical data and divided into two groups according to different surgical methods. Proximal femoral nail antirotation(PFNA) was used for treatment in PFNA group, while Gamma3 was used for treatment in Gamma3 group. There were 48 patients in each group. Perioperative indexes, Harris scores and the complication occurrence were compared between the two groups. Results The operation time, incision length and hospital stay in PFNA group were shorter than Gamma3 group, and the difference was statistically significant(P<0.05). There was no significant difference in weight-bearing time and bone healing time between the two groups(P>0.05). There was no significant difference between Gamma3 group(85.41%) and PFNA group(87.50%)(P>0.05). The complication rates of Gamma3 group and PFNA group were 14.58% and 6.25%, respectively, and the difference was not statistically significant(P>0.05). Conclusion Gamma3 nails and antirotation proximal femoral nails have similar efficacy in the treatment of unstable intertrochanteric fractures in the elderly, but PFNA has the characteristics of less incision trauma, faster recovery, and better prognosis complications.更多还原
