    Author: Lu CK, Fu YC, Cheng YM, Huang PJ.
    Journal: Kaohsiung J Med Sci; 2014 Sep; 30(9):471-6. PubMed ID: 25224771.
    Abstract:
    This study aims to describe the clinical results of isolated talonavicular arthrodesis in rare Müller-Weiss disease, spontaneous osteonecrosis of the navicular in adults. From June 2001 to April 2010, we performed isolated talonavicular arthrodesis on 13 feet of 13 patients (mean age: 55.6 years) with Müller-Weiss disease. The feet were staged by the preoperative radiographs according to the Maceira classification. The average modified American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score improved from 48.5 points preoperatively to 87.2 points at final follow-up (mean 51 months, range 10-114 months). Union was achieved in 10 cases (76.9%). If the subtalar and calcaneocuboid joints are relatively healthy, isolated talonavicular arthrodesis may be an effective and reliable surgical option for treatment of Müller-Weiss disease that is resistant to conservative treatment.
