目的探讨胫腓骨开放骨折行Taylor空间支架外固定术后,轴向应力刺激对促进骨折愈合的临床疗效。方法回顾分析2015年1月—2016年6月收治的符合选择标准的45例胫腓骨开放骨折患者临床资料,均行Taylor空间支架闭合复位外固定术,根据术后是否进行轴向应力刺激分为试验组(23例)和对照组(22例)。两组患者性别、年龄、侧别、致伤原因、骨折分型及受伤至手术时间等一般资料比较,差异均无统计学意义(P>0.05),具有可比性。术后对试验组进行轴向应力刺激;两组均行轴向载荷分担比值测试,该值<10%时拆除外固定。记录并比较两组患者骨折愈合时间、完全负重时间及拆除外固定支架时间;拆除外固定支架6个月后,参照Johner-Wruhs胫骨干骨折治疗最终效果评价标准评定患肢功能。结果试验组和对照组各有2例和3例发生针道异物反应,予以对症抗过敏治疗后好转。45例患者均获随访,随访时间8~12个月,平均10个月。患者骨折均达临床愈合,无延迟愈合、不愈合及骨髓炎等并发症发生。试验组骨折愈合时间、完全负重时间和拆除外固定支架时间均显著短于对照组(P<0.05)。拆除外固定支架6个月后,参照Johner-Wruhs胫骨干骨折治疗最终效果评价标准评定患肢功能,试验组优13例、良6例、中3例、差1例,优良率82.6%;对照组优5例、良10例、中4例、差3例,优良率为68.2%;两组比较差异有统计学意义(Z=–2.146,P=0.032)。结论 Taylor空间支架外固定术后行轴向应力刺激能促进胫腓骨开放骨折的愈合,促进骨折处局部骨形成。
Objective To investigate the effect of axial stress stimulation on tibial and fibular open fractures healing after Taylor space stent fixation. Methods The data of 45 cases with tibial and fibular open fractures treated by Taylor space stent fixation who meet the selection criteria between January 2015 and June 2016 were retrospectively analysed. The patients were divided into trial group （23 cases） and control group （22 cases） according to whether the axial stress stimulation was performed after operation. There was no significant difference in gender, age, affected side, cause of injury, type of fracture, and interval time from injury to operation between 2 groups （P〉0.05）. The axial stress stimulation was performed in trial group after operation. The axial load sharing ratio was tested, and when the value was less than 10%, the external fixator was removed. The fracture healing time, full weight-bearing time, and external fixator removal time were recorded and compared. After 6 months of external fixator removal, the function of the limb was assessed by Johner-Wruhs criteria for evaluation of final effectiveness of treatment oftibial shaft fractures. Results There were 2 and 3 cases of needle foreign body reaction in trial group and control group, respectively, and healed after symptomatic anti allergic treatment. All the patients were followed up 8-12 months with an average of 10 months. All the fractures reached clinical healing, no complication such as delayed union, nonunion, or osteomyelitis occurred. The fracture healing time, full weight-bearing time, and external fixator removal time in trial group were significantly shorter than those in control group （P〈0.05）. After 6 months of external fixator removal, the function of the limb was excellent in 13 cases, good in 6 cases, fair in 3 cases, and poor in 1 case in trial group, with an excellent and good rate of 82.6%; and was excellent in 5 cases, good in 10 cases, fair in 4 cases, and poor in 3 cases in control group, with an excellent and good rate of 68.2%, showing significant difference between 2 groups （Z=-2.146, P=0.032）.Conclusion The axial stress stimulation of Taylor space stent fixation can promote the healing of tibial and fibular open fractures and promote local bone formation at fracture site.
