框式小腿外固定架的研制与临床应用

Design and Clinical Application of Tibial Frame-like External Fixator

从１９８２年２月～１９８８年６月，我们采用自行设制的框式小腿外固定架，共收治各种原因所致下肢不等长和胫腓骨骨折患者５２１例。其中男３３９例。女１８２例。骨骺牵开延长术３１１例，获骨延长长度２．５～１３ｃｍ，平均５．１ｃｍ，骨愈合时间５６～５４０天，其中２８６例平均１１０天获骨愈合。胫骨上干骺端截骨延长１１８例，获骨延长长度２．５～９．５ｃｍ，平均４．１ｃｍ，骨愈合时间７９～３９０天，其中１１２例平均１２４天获骨愈合。胫腓骨骨折复位固定术９２例，发生骨迟缓愈合１例，其余病例骨愈合时间５４～１８０天，平均９２天。从力学角度分析，该固定架具有良好的稳定性，结构设计合理。

AbstractFrom February 1982 to June 1988,the authors had used the self designed framelike tibial external fixator for the treatment of 521 cases of lower limb inequality of various causes. There were 339 males and 182 females.The age ranged from 8 to 50 years. Epiphyseal distractionwere done in 311 cases,and the increase of length obtaine-dranged from 2.5 to 13cm,with an average of 5.1cm.Bone union occured in 65 to 540 days. Limb Lengtheningby proximal tibial osteotomy were done in 118 cas es. Theincrease of length ranged from 2. 5 to 9. 5cm,with an av-erage of 4. 1cm. Bone union occurred in 79 to 390 days.Fracture of the leg reduction fixation occurred in 92 case-s. One case had delayed union. The authors concluded thatthis external fixation device is charaterized by its good sta-bility,reasonable design and flexible adjustment on the ba-sis of the analysis of dynamics
