Müller-Weiss Disease.

Müller-Weiss disease is a rare condition of osteonecrosis of the lateral navicular with dorsal midfoot pain. The predominant treatment discussed in the literature is surgery. This report focuses on a single case using conservative treatment, including pain medication, ethylene vinyl acetate custom orthotics, motion control shoes, physiotherapy for strengthening intrinsic foot muscles, and weight management. The primary complaint from the patient was midfoot pain limiting activities of daily living. After application of conservative treatment modalities and 10 months of follow-up, bilateral midfoot pain decreased from 9/10 to 2/10. To the authors' knowledge, this is the first case report of successful conservative treatment of bilateral Müller-Weiss disease in a patient with multiple comorbidities using pain medication, ethylene vinyl acetate custom orthotics, motion control shoes, physiotherapy, and weight management.
