摘要 目的 在单侧多功能外固定架的基础上研制具有双平面固定作用的外固定架。方法 在原固定架的万向球头设计纵杆 ,钢针夹块为独立结构 ,由上、下夹块和 3枚螺钉组成 ,下夹块夹持钢针 ,其与纵杆连接 ,可多角度旋转 ,任意选择穿针平面。结果 临床应用 85例 ,经 1~ 3 5年随访 ,骨折均一期愈合 ;带架时间 4~ 10个月 ,平均 6个月 ;患肢功能恢复良好。结论 该支架在继承原支架优点的基础上 ,形成双平面固定系统 ,抗弯曲、抗扭转力量强 ,可对斜形、螺旋形骨折加压固定 ,且钢针穿放的随意性强 ,适用于四肢各类骨折。 Objective To design a new external fixator with double plane fixation ability on the basis of unilateral multifunctional external fixation apparatus. Methods Design a vertical pole in universal globle head, an independent screw nip steatite was composed of upper, lower nip steatite and three snails, which was connected with vertical pole to choose screw insertion area at will. Results 80 patients were treated with this external fixator. After patients were followed up for 1~3 5 years, all the fractures healed up in 4~10 months, 6 months on average, and with good function in all cases. Conclusion The double plane UMEFA inherits the advantages of UMEFA, formed a double plane fixation system, strengthen the ability of anti rotation and anti curve, especially has a compressive fixation to incline, helicity fractures, meanwhile improves the probability of screw insertion. Therefore it can be used for the treatment of various types of fractures and non union of bone.
