三维复位固定器治疗胫腓骨骨折

Treatment of fracture of tibia and fibula with three dimensional diaplasis fixation

目的:观察研究三维复位固定器治疗胫腓骨骨折的临床疗效。方法:胫腓骨骨折患者21例,男12例,女9例;年龄18～72岁,平均46岁。开放性骨折5例,闭合骨折16例。上段骨折4例,中段骨折8例,下段骨折9例。斜形骨折10例,粉碎骨折8例,多段骨折3例。采用三维复位固定器进行治疗。结果:骨折复位情况:解剖对位11例,近解剖对位9例,功能对位1例。骨折临床愈合时间43～85d,平均62d。随访4～12个月,功能恢复优13例,良8例。多功能复位固定器拆除时间6～12周,平均8.5周。结论:三维复位固定器治疗胫腓骨骨折使固定器与骨折端形成三维立体固定,适合小腿的生物力学要求,为胫腓骨骨折治疗提供了一种既无偏心应力,又无应力遮挡,结构稳固利于骨折愈合的弹性固定器。

Objective：To study the clinical effect of three dimensional diaplasis fixation in fracture of tibia and fibula. Methods ：Twenty-one cases of fracture of tibia and fibula were treated with three dimensions fixation（ 12 males ,9 females ,with an average age of 46 years）. There were 5 cases in open fracture, 16 cases in closed fracture, and 4 cases in up-segment fracture, 8 cases in mid-segment fracture, 9 cases in below-segment fracture. Oblique fracture were in 10 cases, thrypsis were in 8 cases, muhisegmental fracture were in 3 cases. Results： （1）Conditions of diaplasis fracture：dissected diaplasis were in 11 cases, closely dissected diaplasis in 9 cases, functional diaplasis in 1 case. （2）Clinical healing time：the minimum time was 43 days and maximum time was 85 days with an average of 62 days. （3）Conditions of functional recovery ： all the patients were followed up from 4 to 12 months, 13 cases were excellent, 8 cases were good. （4）Time of backouting three dimensional diaplasis fixation ： the minimum time was 6 weeks and the maximum 12 weeks with an average time of 8.5 weeks. Conclusion：The three dimensional diaplasis fixation and the fracture extremity from such a three dimensional solid that it can satisfy crus biomechanics for treating fracture of tibia and fibula with unstressed barrier and uncentric stress. Moreover, the three dimensional diaplasis fixation is elastic, it＇s structure is so fixed that it can be favorable for bone union.
