Abstract

Background

The surgical treatment of hallux valgus (HV) deformity has been the subject of countless publications but few focus on the altered windlass mechanism or analyze the biomechanical behavior immediately after surgery.

Methods

Patients treated for HV between January and March 2023 were included. The surgery consisted of a L-reverse first metatarsal osteotomy. To analyze the windlass mechanism we record two different measurements; the isolated first metatarsophalangeal joint (MTPJ) dorsiflexion angle (IDA) and dynamic plantarization of the first metatarsal head when performing first MTPJ dorsiflexion imprinting a mark on a modeling foam.

Results

A total of 30 patients diagnosed with symptomatic HV were included. In all patients, a change in the IDA angle was evident, being overall statistically significant. About modeling foam imprinted mark, all measurements, in all planes of space, had a clear tendency to increase, which turned out to be statistically significant (p < 0.001).

Conclusions

An altered windlass mechanism may be successfully recovered immediately after hallux valgus deformity surgery. This could be evinced by an indirect measurement analyzing the imprint of the head of the first metatarsal in a modeling foam and the IDA.

拇指外翻手术对第一缕胫骨生物力学行为的直接影响

关于拇指外翻（HV）畸形的手术治疗已发表了无数文章，但很少有文章关注辘轳机制的改变或分析术后的生物力学行为。本文纳入了 2023 年 1 月至 3 月间接受 HV 治疗的患者。手术包括 L 型反向第一跖骨截骨术。为了分析辘轳机制，我们记录了两个不同的测量值：孤立的第一跖趾关节（MTPJ）背屈角（IDA）和在第一跖趾关节背屈时第一跖骨头的动态足底化，并在模型泡沫上印上标记。共有 30 名患者被诊断为有症状的 HV。在所有患者中，IDA角度的变化都很明显，总体上具有统计学意义。关于模型泡沫印记，在所有空间平面上的所有测量值都有明显的增加趋势，这在统计学上具有显著意义（p < 0.001）。辘轳机制的改变可以在拇指外翻畸形手术后立即恢复。通过间接测量分析第一跖骨头在模型泡沫中的印迹和 IDA 可以证明这一点。无

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.
