Müller-Weiss disease: What do we know so far? – Review of current knowledge

Abstract

BackgroundMüller-Weiss disease is a rare hindfoot and midfoot condition that causes a paradoxical flatfoot with hindfoot varus in advanced cases. Clinicians should be aware of the current evidence-based literature to provide optimal care. Materials and MethodsA narrative review was conducted using pubmed© database browser. The data was then compiled, analysed and organized into an original text with the latest articles in the matter included. ResultsNavicular fragmentation, talonavicular joint destruction, and mid/rear foot arthritis are common in MW disease. Diagnosis is made through clinical evaluation and simple x-rays. Conservative treatment may involve modifying footwear, while surgical treatment should correct the varus deformity, relieve pain, restore the plantar arch, and release gastrocnemius tightness. Patients with mild disease may be eligible for navicular fragment excision and/or decompression, but results are often unsatisfactory. In moderately advanced stages, isolated talo-navicular arthrodesis is a possibility. In severe stages, double or triple arthrodesis in association with lateral displacement calcaneal osteotomy can be considered. ConclusionsMüller-Weiss disease is a rare and complex condition that causes foot pain and deformity. Its exact cause is not yet known, but it is believed to have multiple factors. Surgical management aims to correct deformities, fuse painful joints, and restore the foot's arch.10.1016/j.fuspru.2024.03.002
