摘要
目的 探讨长髓内钉与短髓内钉治疗AO/OTA 31-A3型股骨转子间骨折的疗效。 方法 回顾性收集2019年3月至2022年8月采用髓内钉治疗的AO/OTA 31-A3型股骨转子间骨折患者60例。接受长髓内钉治疗的长钉组34例，男16例、女18例，年龄（68.41±17.84）岁（范围31~96岁）；接受短髓内钉治疗的短钉组26例，男13例、女13例，年龄（72.23±13.97）岁（范围31~90岁）。对比两组受伤原因、骨折AO/OTA分型、术中失血量、手术时间、骨折愈合时间、影像学指标（骨折复位质量、术后颈干角、内侧支撑）、末次随访髋关节Harris评分、术后1年内死亡率及并发症的差异。 结果 长钉组随访时间（24.26±6.67）个月、短钉组为（24.31±5.60）个月，两组性别、年龄、致伤原因、侧别、骨折AO/OTA分型、术前实验室检查、是否合并血栓或高血压或糖尿病的差异均无统计学意义（P>0.05）。长钉组术中出血量（281.47±235.28）ml、手术时间（110.44±24.63）min，短钉组分别为（121.92±84.14）ml、（81.15±28.54）min，差异均有统计学意义（P<0.05）。长钉组住院时间为（12.35±4.81）d、骨折复位良好率为55.9%、骨折愈合时间为（120.44±16.43）d、内侧支撑存在率为67.6%、末次随访髋关节Harris评分优良率为79.4%，短钉组分别为（10.89±4.30）d、61.53%、（128.07±18.33）d、65.4%、65.4%，两组差异无统计学意义（P>0.05）。长钉组并发症为切口浅表感染、骨折延迟愈合、骨折不愈合、头钉切出各1例，短钉组包括浅表切口感染1例、骨折延迟愈合2例、骨折不愈合1例；长钉组1年内死亡率为5.3%、并发症发生率为11.7%，短钉组分别为7.1%、15.4%，差异无统计学意义（P>0.05）。 结论 长髓内钉与短髓内钉治疗AO/OTA 31-A3型股骨转子间骨折均能获得良好的固定效果与临床疗效，其中短髓内钉手术时间更短，术中出血量更少。 Objective To explore the efficacy of long intramedullary nails versus short intramedullary nails in the treatment of AO/OTA 31-A3 intertrochanteric fractures. Methods A retrospective analysis was conducted on 60 patients with AO/OTA 31-A3 intertrochanteric femur fractures treated between March 2019 and August 2022. The patients were randomly divided into two groups (the long nail group and the short nail group). Thirty-four patients were treated with long intramedullary nails, including 16 males and 18 females, aged 68.41±17.84 years old (range 31-96 years). Twenty-six patients were treated with short intramedullary nails, including 13 males and 13 females, aged 72.23±13.97 years old (range 31-90 years). The causes of injury, fracture classification (AO/OTA classification), intraoperative blood loss, operation time, fracture healing time, imaging indexes (fracture reduction quality, postoperative neck trunk angle, and medial support), Harris score of the hip joint at the last follow-up, one-year mortality rates and complications were compared between the two groups. Results The follow-up time was 24.26±6.67 months in the long nail group and 24.31±5.60 months in the short nail group, and the general information of the two groups were comparable. Between the long nail and short nail group, the intraoperative blood loss was 281.47±235.28 ml vs. 121.92±84.14 ml and the operation time was 110.44±24.63 min vs. 81.15±28.54 min with significant differences (P<0.05). While the length of hospital stay was 12.35±4.81 dvs. 10.89±4.30 d, the good rate of fracture reduction was 55.9% vs. 61.53%, the fracture healing time was 120.44±16.43 d vs. 128.07±18.33 d, the presence rate of medial support was 67.6% vs. 79.4%, and the excellent rate of Harris score was 65.4% vs. 65.4% with no significant difference between the two groups (P>0.05). One-year mortality rates was 5.3%vs. 7.1% and complications was 11.7% vs. 15.4% with no significant difference between the two groups (P>0.05). Conclusion Both long intramedullary nails and short intramedullary nails are effective in the treatment of AO/OTA 31-A3 intertrochanteric femur fractures. However, surgical time and intraoperative blood loss was less in the short nail group.
