Abstract

Background: The Zadek osteotomy modified by Taylor (ZO) is a surgical technique used to treat insertional Achilles tendinopathy (IAT) by reducing the heel's prominence and elevating the Achilles tendon insertion. This study aims to analyze the biomechanical consequences of IAT after ZO using a virtual surgical simulation with a specific software.

Methods: A retrospective analysis of 20 wtbearing computed tomography (WBCT) scans of IAT patients was conducted. Using Disior's BonelogicTM software, 3D models were created from WBCT images. Virtual ZO was performed on these models, and various biomechanical parameters were measured before and after the virtual osteotomy.

Results: The virtual ZO showed significant statistical differences in the average of the calcaneal length (p < 0.001), Fowler Philips angle (p < 0.001), calcaneal pitch (p < 0.001), and the sagittal talocalcaneal angle (p < 0.001).

Conclusions: The virtual ZO analysis suggests that this procedure can decrease the Fowler Philips angle, shorten the calcaneus, modifying specifically the sagittal alignment.

Level of evidence: IV; case series.

Zadek截骨术对插入性跟腱病的生物力学影响：虚拟手术模拟研究。

背景：经泰勒改良的Zadek截骨术（ZO）是一种用于治疗插入性跟腱病（IAT）的手术技术，通过减少足跟的突出度并抬高跟腱插入部。本研究旨在利用特定软件进行虚拟手术模拟，分析 ZO 后 IAT 的生物力学后果：方法：对 20 例 IAT 患者的负重计算机断层扫描（WBCT）进行了回顾性分析。使用 Disior 的 BonelogicTM 软件，根据 WBCT 图像创建了三维模型。在这些模型上进行了虚拟 ZO，并测量了虚拟截骨前后的各种生物力学参数：结果：虚拟 ZO 在小腿骨平均长度（p < 0.001）、Fowler Philips 角度（p < 0.001）、小腿骨间距（p < 0.001）和矢状距髋臼角（p < 0.001）方面显示出明显的统计学差异：虚拟ZO分析表明，该手术可减少Fowler Philips角，缩短小腿骨，特别是改变矢状线：证据等级：IV；病例系列

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.
