摘要

导言：进行性塌陷性柔性足畸形通常采用保关节技术治疗。我们的目的是评估不同的跟骨截骨术，有或没有腓骨短肌到长肌转移（PBtoPL）对尸体扁平足模型的生物力学影响。方法：采用15具尸体足、踝标本建立中位期步态模型。Evans、medial displacement、Double、Z （step cut）和IZ（倒Z）截骨比较。采用Vicon定位系统测量角度变化。结果：Evans和双截骨术内收效果最好；Z和IZ截骨术减少50% %。Evans， Double和IZ截骨术产生了显著的旋后效果。PBtoPL迁移产生了不显著的变化。结论：Evans和双截骨术是最有效的跟骨截骨术。Evans， Double和IZ截骨术具有相似的旋后效果。需要进一步的研究来更详细地探讨PBtoPL肌腱转移的作用。

Biomechanical comparison in a cadaveric flatfoot model between different calcaneal osteotomies with and without transfer from the peroneus brevis to the longus.

Introduction: Progressive collapsing flexible foot deformities are generally treated with joint-preserving techniques. Our objective was to evaluate biomechanically the effect of different calcaneal osteotomies with or without a peroneus brevis to longus transfer (PBtoPL) on a cadaveric flatfoot model.

Methods: 15 cadaveric foot and ankle specimens were used in a mid-stance phase of gait model. Evans, medial displacement, Double, Z (step cut), and IZ (inverted Z) osteotomies were compared. A Vicon positioning system was used to measure angular changes.

Results: Evans and Double osteotomies generated the highest adduction effect; Z and IZ osteotomies generated 50 % less. Evans, Double and IZ osteotomies created a significant supination effect. The PBtoPL transfer produced non-significant changes.

Conclusions: Evans and Double osteotomies were the most potent calcaneal osteotomies. Evans, Double, and IZ osteotomies had a similar supination effect. Further studies are needed to explore the role of the PBtoPL tendon transfer in greater detail.

期刊介绍： Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society. The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
