AbstractMüller-Weiss Disease (MWD) is a rare foot disease with unclear etiology but frequently occurred in women. Due to the resistance to conservative treatment, surgical therapy has gradually occupied a necessary position in the clinical management of MWD. Joint fusion surgery is a commonly used treatment for MWD, which could effectively alleviate pain, correct deformation, and restore function. A total of 12 MWD patients (III-V stage) were enrolled in this study. All patients showed no significant improvement in conservative treatment and further received the triple and talonavicular arthrodesis. All patients were followed up with an average follow-up of 16.8 ± 1.19 months (mean ± SD). The triple and talonavicular arthrodesis significantly ameliorated the pain and walking dysfunction in the affected foot. The American Orthopedic Foot Andankle Society (AOFAS) scores dramatically increased from 43.4 ± 16.1 to 85.3 ± 6.2. Meanwhile, the conducting of triple and talonavicular arthrodesis improved the X-ray length (15.5 ± 0.8 vs. 14.3 ± 0.9 cm) and arch height (18.6 ± 0.9 vs. 10.2 ± 0.7 mm) and reduced the Meary-Tomeno angle (1.3 ± 2.5 vs. 2.14 ± 4.8°). The triple and talonavicular arthrodesis achieved a satisfying therapeutic effect on MWD patients at the III-V stage, which improved patients' outcomes and the quality of life.
