摘要
目的通过与常规手术比较，探讨计算机快速成型辅助个体化治疗三踝骨折的效果。方法2007年3月至2008年3月收治三踝骨折患者24例，随机分为两组，计算机快速成型辅助设计手术组（A组）12例，常规手术组（B组）12例。A组手术前采取CT三维重建、计算机模拟、快速成型与个体化标本预手术。比较两组的切开暴露时间、复位与固定时间及手术疗效优秀率。结果所有患者术后随访8～15个月。两组切开暴露时间差异无统计学意义（t=-1．06，P=0．102）；A组手术复位与固定时间为（45．43±9．38）min，低于B组（58．61±12．32）min，差异有统计学意义（t=-2．948，P〈0．05）；A组手术疗效优秀率为83．3％，B组手术疗效优秀率为66．7％。结论计算机快速成型辅助个体化技术可提高三踝骨折手术效率与精确度。
Objective To compare the operation with computer-aided rapid prototyping technique and the conventional procedure for treatment of trimalleolar fractures. Methods Twenty-four patients with trimalleolar fracture who had been admitted to our hospital from March 2007 to March 2008 were divided into 2 even groups randomly. Group A underwent 3-dimensional reconstruction, computer simulation and rapid prototyping and demonstration of individual fracture model before operation. Group B received only conventional procedures. The therapeutic effects were evaluated by Cedell criteria and compared statistically between the 2 groups. Comparision between the 2 groups was made in the exposure time, reduction and fixation time curative effect. Results Follow-up from 8 to 15 months revealed that the operation time for Group A （45.43 ± 9.38 minutes） was significantly shorter than for Group B （58.61 ±12.32 minutes） （ t = -2. 948, P 〈 0.05）. The exposure time between the 2 groups had no statiscal difference （ t = - 1.06, P = 0. 102）. The excellent rate of curative effect in Group A was 83.3% and 66.7% in Group B. Conclusion Computer aided rapid prototyping can shorten the operation time and improve operational efficiency for trimalleolar fractures.
