Mueller-Weiss syndrome (MWS), or spontaneous osteonecrosis of the tarsal navicular in adults, is a rare cause of chronic medial midfoot pain. MWS has been described in orthopedic, podiatric, and radiologic literature without consensus agreement on its pathophysiology and treatment. We present the radiographic and magnetic resonance imaging of a case of MWS with reference to navicular biomechanical stressors and potential pathogenesis.
