加压固定—潜行截骨延长治疗先天性胫骨假关节

Investigation of Congenital Pseudarthrosis of Tibia with External Skeletal Compression Fixation and Simultaneous Closed Osteotomy Lengthening

目的:探讨加压固定—潜行截骨延长治疗先天性胫骨假关节的疗效。方法:采用加压固定—潜行截骨延长治疗11例先天性胫骨假关节患者。通过彻底切除假关节及周围病变,安装球面万向骨折复位外固定器进行矫正加压并行胫骨近端"针锯"潜行截骨延长。结果:通过随访,11例假关节均获得骨性愈合,2例残留轻度足外翻畸形。结论:加压固定—潜行截骨延长治疗先天性胫骨假关节是一种行之有效的方法。

Ojective：Investigate the efficacy of treatment of congenital pseudarthrosis of tibia with external skeletal compression fixa- tion and simultaneous closed osteotomy lengthening. Methods： 11 cases of congenital pseudarthrosis were treated by external skeletal com- pression fixation and simultaneous closed osteotomy lengthening, after resccting of the pseudarthrosis and tile surrounding pathological changes,two ends of pseudarthrosis were corrected and compressed by performing ＂multiple- plane and double -track elongation instru- ment, and then the tibia of the proximal were extended by ＂needle saw＇. Results ： By following - up, bone union were achieved in all 11 pseudarthrosises, slight valgus deformity of ankle were residued in two patients. Conclusion：It is a practical and safe surgical manner to treat congenital pseudarthrosis of tibia with external skeletal compression fixation and simultaneous closed osteotomy lengthening.
