摘要
目的 建立山羊股骨干骨折模型,对比空心交锁髓内钉和尾丝髓内钉的固定效果。方法 选取40只成年公山羊股骨骨折模型,20只采用空心交锁髓内钉固定（A组）,20只采用尾丝髓内钉固定（B组）。术后4、8周行X线复查并于骨折愈合后取出内固定,对比分析两组手术数据。结果 两组山羊于术后8周骨折均愈合,B组植入手术时间为（37.9±5.1）min、出血量为（38.0±66.O）rnl、术中透视时间为（6.8±3.1）s、取出术时间为（24.4±5.3）min、出血量为（26.3±7.8）rnl,各项数据均小于A组,差异有统计学意义（P〈0.05）,尾帽掉落次数差异无统计学意义（P〈0.05）。B组1只山羊在植入术后死亡。结论 尾丝髓内钉治疗股骨干骨折的疗效与交锁髓内钉相当,但手术时间短,出血量少,X线暴露少,步骤简便。
Objective Toestablish femoral fracture models in goats, and compare the effect of using cannulated interlocking intramedullary nail and intramedullary nail with tail wire . Methods 40 adult male goats were selected, and the bilateral posterior middle femoral fracture models were artificially established. Twenty goats were fixed with cannulated interlocking intramedullary nail （ group A） , and 20 with intramedullary nail with tail wire （group B）. X-ray examination was done at 4th and 8th week postoperatively and the nails were removed after fractures were healed. All the operative data were recorded and analyzed statistically. Results All fractures were healed in about 8 weeks postoperatively. Implanting operative time was （ 37.9 ± 5.1 ） min, blood loss was （ 38.0 ± 66. 0） mL, intraoperative fluoroscopy time was （6. 8 ± 3. 1 ） s, and removal operative time was （24. 4 ± 5.3 ） min, blood loss was （26. 3 ± 7. 8） mL in group B, which were significantly different from those in group A （P 〈0.05 for all）. End cap falls in both groups had no significant differences （ P 〉 0. 05 ）. One goat in group B was died after the implanting operation. Conduslon Intramedullary nail with tail wire in fixing femoral fractures has the same effects as cannulated interlocking intramedullary nail, but it has many advantages, including shorter operative time, less blood loss and X-ray exposure, and simple steps.
