摘　　要：目的:探讨腓骨截取的最佳部位,为临床科学合理的应用腓骨提供理论依据。方法:选取10具172￣176cm成人男性防腐尸体,制作20例成人小腿—足踝标本,分别测量、分析腓骨完整时和在腓骨下1/6、下1/4、下1/3、1/2点处分别向近侧切除10cm长腓骨情况下对胫距关节接触面积及应力分布的改变。结果:腓骨完整时,胫距关节接触总面积为(311.4±19.8)mm2,在腓骨下1/6点处向近侧切除10cm长腓骨后,胫距关节接触面积明显减小,为(259.9±23.1)mm2,平均应力值增高;在腓骨1/2点处向近侧切除同样长腓骨后,胫距关节接触面积变化不明显,为(306.4±20.3)mm2,平均应力无显著变化。结论:腓骨最佳截取部位在腓骨1/2点处的近侧段。Objective： To investigate the best part of the fibular resection and provide reference for clinical application of fibular resection reasonably. Methods： Ten adult male cadaveric spocimens including the leg and ankle, with the length of 172-176 cm were used. At the states of the normal circumstance, fibular resection from the lower 1/6, 1/4, 1/3, and 1/2 to the proximal part of the fibula about 10cm, the contact surface and the stress distribution of tibiotalar joint were measured and analyzed respectively. Results： Normally, the contact area of tibiotalar joint was about （311.4±19.8） mm^2. Under the condition of cutting fibula from the lower 1/6, contact area of tibiotalar joint reduced to （259.9±23.1） mm^2 and the average stress increased. In contrast, under the condition of cutting fibula about 10 cm from the middle 1/2, there were a little effect on contact area （306.4± 20.3） mm^2 and average stress of tibiotalar joint. Conclusions： The best part of the fibular resection is the proximal 1/2 part of the fibula.
