计算机导航辅助加压塑形钢板治疗复杂性跟骨骨折

目的利用计算机导航系统辅助内固定治疗复杂性跟骨骨折。方法利用计算机导航系统治疗复杂性跟骨骨折110例,130侧,术前根据跟骨X线片及64层螺旋CT扫描结果进行分型,其中Sander’s H型57例,Ⅲ型45例,Ⅳ型28例。结果所有患者均获6—24个月。平均16．3个月随访。术后X线片显示跟骨高度、宽度、长度及Bolhor’s角,Gissane’s角均恢复,无一例切口感染。按Maryland足部评分系统评价术后功能。本组130侧中,优（90—100分）63侧（48．46％）,良（75—89分）57侧（43．85％）,可（50—74）10侧（7．69％）,优良率92．31％。结论计算机导航治疗复杂性跟骨骨折可获得满意的临床疗效。

Treatment of complex calcaneal fractures under computer navigation: report of 130 feet

OBJECTIVE: To investigate the effects of computer navigation in the treatment of intra-articular calcaneal fractures. METHODS: 130 feet in 110 patients with intra-articular calcaneal fractures, 57 calcanei with fracture of Sander's type II, 45 of type III, and 28 cases of type IV, were treated with internal fixation under computer navigation, and were followed up for 16.3 months (6 - 24 months). RESULTS: According to the Maryland Foot Score system, excellent result was noted in 63 feet, good result in 57 feet, and fair result in 10 feet, with the excellent and good rates being 92.31% together. CONCLUSION: Using computer navigation to treat intra-articular calcaneal fractures is one of the best ways for treatment of calcaneal fractures.
