To analyze the treatment of elderly femoral intertrochanteric fracture (EFIF) using InterTan intramedullary nail (InterTanIN) and proximal femoral nail antirotation (PFNA). A total of 75 patients suffering from EFIF receiving intramedullary fixation were retrospectively collected. According to intramedullary fixation methods, the patients were separated into InterTanIN group and PFNA group. Parameters including the surgery time, blood loss, number of X-ray fluoroscopy, hospital stays, bone-healing time, postoperative Harris hip score (HIS) (1 month, 3 months, 6 months, and 12 months), and complications were collected and analyzed. The results showed surgery time, blood loss, and number of X-ray fluoroscopy in InterTanIN group were higher than those in PFNA group ( < 0.05). The mean hospital stay in the InterTanIN group was comparable to that in the PFNA group ( > 0.05). There was no significant difference in bone-healing time between the InterTanIN group and PFNA group ( > 0.05). The postoperative HIS of InterTanIN group was statistically better than PFNA group at the 3rd month and the 6th month ( < 0.05). With the extension of recovery time, the gap between the two groups gradually narrowed. The postoperative implant displacement happened more often in the PFNA group than in the InterTanIN group. EFIF treated with InterTanIN or PFNA could achieve good long-term efficacy. Although InterTanIN has the disadvantages of increased operative time, blood loss, and radiation exposure compared to PFNA, the postoperative hip function recovery of InterTanIN seems to be more reliable and stable than PFNA.
分析使用InterTan髓内钉（InterTanIN）和股骨近端抗旋髓内钉（PFNA）治疗老年股骨转子间骨折（EFIF）的效果。回顾性收集75例接受髓内固定治疗的EFIF患者。根据髓内固定方法，将患者分为InterTanIN组和PFNA组。收集并分析手术时间、出血量、X线透视次数、住院时间、骨愈合时间、术后Harris髋关节评分（HIS）（1个月、3个月、6个月和12个月）以及并发症等参数。结果显示，InterTanIN组的手术时间、出血量和X线透视次数均高于PFNA组（P<0.05）。InterTanIN组的平均住院时间与PFNA组相当（P>0.05）。InterTanIN组和PFNA组的骨愈合时间差异无统计学意义（P>0.05）。InterTanIN组术后第3个月和第6个月的HIS在统计学上优于PFNA组（P<0.05）。随着恢复时间的延长，两组之间的差距逐渐缩小。PFNA组术后植入物移位的发生率高于InterTanIN组。使用InterTanIN或PFNA治疗EFIF均可取得良好的长期疗效。虽然与PFNA相比，InterTanIN存在手术时间延长、出血量增加和辐射暴露增加的缺点，但InterTanIN术后髋关节功能恢复似乎比PFNA更可靠、更稳定。
