    摘要:

    目的:初步探讨远骨折端牵引固定技术在胫骨开放性骨折早期治疗中的应用效果。方法:回顾性分析我院2012年2月至2017年8月间处理的96例胫骨开放骨折,其中40例在损伤控制性手术时采用远骨折端外支架牵引固定(牵引外固定组),56例采用常规外支架技术(常规外固定组)。记录两组外固定操作时间、转内固定时间间隔、针道感染率、确定性内固定手术持续时间,和随访负重时间、关节活动度、VAS评分、术后感染率,及末次随访放射学评估和Johner—Wruhs评分。 结果:所有病例随访至确定性内固定术后14~25个月。两组间外固定操作时间、针道感染率,转确定性手术时间间隔和确定性手术时间差异均有统计学意义(P<0.05)。两组间开始负重时间、完全负重时间、膝关节ROM、踝关节ROM差异均无统计学意义(P>0.05)。末次随访VAS评分、Johner-Wruhs评分优良率、术后感染率两组间差异均无统计学意义(P>0.05)。骨折愈合时间、术后胫骨内-外翻角度、前-后屈角度两组间差异无统计学意义(P>0.05)。 结论:采用远骨折端外支架牵引固定方法早期临时固定开放性胫骨骨折,对确定性手术区域软组织干扰小,转确实性手术时间间隙更短,术后感染率更低。

    Abstract:

    Objective:To investigate the preliminary outcomes and application principles of self-tension inter-reverse skeletal tractionfor temporary immobilization to manage open tibial fracture. Methods:The clinical data of 96 open tibial fractures treated in our institution from February 2012 to August 2017were retrospectively analyzed. Forty cases were treated with self-tension inter-reverse skeletal traction (Study group) and 56 cases were treated with traditional external fixator(Control group). Documented the time consumed for temporary immobilization, the interval of conversion from temporary immobilization to definitive fixation, the pin tract infection rate, the interval between external fixation to definitive internal fixation, and the weight bearing commencing time,range of motion of adjacent joints, VAS scoring, postoperative infection rate and radiographic evaluation of fracture reduction and Johner—Wruhs criteria for evaluation at the last follow-up. Results:All patients were followed up for 14 to 25 months after definitive internal fixation. The study group had a significantly shorter time consumed for temporary immobilization, a shorter the interval between external fixation to definitive internal fixation, and a shorter time consumed in the definitive internal fixation, all with significant differences (P<0.05). The times of commencing weight bearing and total weight bearing, ROM of the knee and ankle joints proved no significant differences between the two groups(P>0.05). At the last follow-up, no significant difference was proved in the VAS scoring and the excellent and good rate according to Johner-Wruhs criteria between the two groups(P>0.05). The healing time and the postoperative residual varus-valgus and anteroposterior angulations proved no statistically significant between the two groups(P>0.05). Conclusion:With less invasive interference to the definitive surgery zone, the use of self-tension skeletal traction to provisionally stabilize open tibial fractures could impart shorter interval of conversion from external fixation to definitive fixation and lower infection rate.
