便携式下肢手术支架在胫骨交锁髓内钉固定操作中的应用研究

Application of portable bracket of lower limb in the operation of tibia interlocking intramedullary nail

[目的]研制便携式下肢手术支架并应用于胫骨交锁髓内钉内固定术操作,观察其临床应用效果。[方法]自2005年2月～2009年4月,将便携式下肢手术支架应用于115例的胫骨交锁髓内钉内固定术中操作(支架组),并与81例常规胫骨交锁髓内钉内固定术中操作(非支架组)的临床效果比较。[结果]两组病例均获随访,在发病年龄、骨折类型及骨折部位等的统计学分析显示无明显差异;而支架组在参加手术人数、手术时间、开放复位例数、手术人员受辐射次数方面较非支架组有显著性差异,骨折愈合时间虽较非支架组有缩短,但统计学上无明显差异。无切口感染、断钉、内固定失效病例。[结论]便携式下肢手术支架制作方法简单,成本低廉,应用于胫骨交锁髓内钉固定术中,具有节省人力、手术更微创和减少辐射损伤及手术并发症等优点。

[Objective] To introduce a newly-developed portable bracket for tibia interlocking intramedullary nail treatment and evaluate its clinical treatment effect.[Method]From February 2005 to April 2009,portable bracket of lower limb were used in the operation of tibia interlocking intramedullary nail for 115 patients （bracket group）,while routine method were performed for 81 cases（non-bracket group） .[Result]All the cases were followed up.There weren＇t significant differences between the two groups in the age,fracture types and sites.There were significant differences between the two groups in the number of operative members,the operative time ,number of open reduction and times of radiation.The fracture clinical union period was lower than in the non-bracket treated cases,but with no statistics difference.There was no infection,no breakage of nails or fall of the internal fixations.[Conclusion]Portable bracket of lower limb is easy to make,and cost little money.The application of tibia interlocking intramedullary nail could save on manpower,reduce the radiation injury,and the operation is more microtraumatic.
