摘要
目的比较Ⅱ型、Ⅴ型腓骨瓣重建跟骨缺损的临床效果。方法建立Ⅴ型和Ⅱ型的简化模型,分别模拟采用Ⅱ型V型腓骨瓣重建跟骨缺损,以结构力学计算得到的位移作为评价足功能指标,进行理论分析进而比较两者的稳定性。结果建立了Ⅱ型腓骨瓣与Ⅴ型腓骨瓣修复简化模型并得到分析后的理论数据。理论计算表明,Ⅱ型腓骨瓣的稳定性优于Ⅴ型。两种重建术式后,Ⅱ型、Ⅴ型腓骨瓣均修复成跟骨样形态。结论从力学角度和临床效果考虑,跟骨缺损必须修复,比起Ⅴ型来,Ⅱ型腓骨瓣相对稳定性较好。
Objective To compare the clinic effect of reconstructing the calcaneus defect with the Ⅱ -shaped and V-shaped fibula flap. Methods First by establishing the simplified model of the Ⅱ -shaped and V-shaped fibula flap, simulating the reconstruction of the heel defect, than we compared the stability as the index of evaluating the functions by structural mechanics. Results Theoretical data were gained based on the simplified model. Theoretical calculation indicated that the stability of Ⅱ -shaped had an obvious advantage than V-shaped. After reconstructing with two methods, both fibular flaps have been modified as calcaneus to satisfy the new circumstance. Conclusion Considering the fact that the defect of heel needs restoration for mechanics and clinic, the Ⅱ-shaped fibula flap is superior in stability than that of Ⅱ-shaped.
