摘　　要：[目的]比较股骨近端仿生髓内钉(proximal femur bionic nail,PFBN)与InterTAN髓内钉治疗老年不稳定型股骨粗隆间骨折的疗效。[方法]回顾性分析2021年6月—2022年12月本院手术治疗的35例老年不稳定型股骨粗隆间骨折患者的临床资料。根据术前医患沟通结果,16例采用PFBN固定,19例采用InterTAN固定。比较两组围手术期、随访及影像学资料。[结果]所有患者均顺利完成手术。虽然PFBN组手术时间[(111.6±15.9)min vs(98.9±15.9)min,P=0.025]、切口长度[(11.9±0.9)cm vs(10.9±1.1)cm,P=0.006]、术中透视次数[(19.2±2.6)次vs(14.6±1.9)次,P<0.001]和术中失血量[(145.6±2.6)ml vs(120.5±31.1)ml,P=0.043]显著大于InterTAN组,但前者术后下地行走时间显著早于后者[(19.1±2.0)d vs(23.8±3.2)d,P<0.001]。两组患者随访时间平均(14.7±2.6)个月,PFBN组恢复完全负重活动时间显著早于InterTAN组[(51.6±4.9)d vs(66.7±7.3)d,P<0.001]。随时间的推移,两组VAS评分显著下降(P<0.05),而Harris评分、髋伸屈ROM、内-外旋ROM均显著增加(P<0.05)。PFBN组术后1个月[(64.9±5.4)vs(55.0±5.7),P<0.001]和术后3个月[(73.1±4.8)vs(67.7±5.3),P=0.004]的Harris评分均显著优于InterTAN组。影像方面,两组骨折复位质量、骨折愈合时间的差异均无统计学意义(P>0.05)。末次随访时,PFBN组股骨颈干角(fem⁃oral neck-shaft angle,FNSA)显著大于InterTAN组(P<0.05),而尖项距(tip-apex distance,TAD)显著小于InterTAN组(P<0.05)。[结论]采用PFBN治疗老年不稳定型股骨粗隆间骨折缩短了卧床时间,允许患者早期下地及负重行走,促进了机体功能的恢复,减少髋内翻。[Objective]To compare the efficacy of proximal femoral bionic nail(PFBN)and InterTAN intramedullary nail for unstable intertrochanteric fractures of the femur in the elderly.[Method]A retrospective analysis was conducted on 35 elderly patients with unstable intertrochanteric fractures of the femur who underwent surgical treatment in our hospital from June 2021 to December 2022.According to preoperative doctor-patient communication,16 cases had the fractures fixed with the PFBN,while the remaining 19 cases were fixed with the InterTAN.The perioperative,follow-up,and imaging data were compared between two groups.[Result]All patients in both groups had corresponding surgical procedure completed successfully.Although the PFBN group had significantly greater surgical time[(111.6±15.9)min vs(98.9±15.9)min,P=0.025],incision length[(11.9±0.9)cm vs(10.9±1.1)cm,P=0.006],intraoperative fluoroscopy frequency[(19.2±2.6)times vs(14.6±1.9)times,P<0.001],and the intraoperative blood loss[(145.6±2.6)ml vs(120.5±31.1)ml,P=0.043],compared to the InterTAN group,the former had significantly earlier postoperative walking time than the latter[(19.1±2.0)d vs(23.8±3.2)d,P<0.001].The follow-up period lasted for(14.7±2.6)months in a mean,and the PFBN group had a significantly earlier recovery of full weight-bearing ac⁃tivity than the InterTAN group[(51.6±4.9)days vs(66.7±7.3)days,P<0.001].The VAS scores significantly decreased(P<0.05),while Har⁃ris scores,hip flexion-extension ROM,and internal-external rotation ROM significantly increased in both groups over time(P<0.05).The PFBN group was significantly better than the InterTAN group regarding Harris score[(64.9±5.4)vs(55.0±5.7),P<0.001]1 month postop⁃eratively,and[(73.1±4.8)vs(67.7±5.3),P=0.004]3 months after operation.As for imaging,there was no statistically significant difference in the quality of fracture reduction and fracture healing time between the two groups(P>0.05).At the last follow-up,the PFBN group remained significantly greater the femoral neck shaft a
