Müller-Weiss Syndrome: Radiological Features and the Role of Weightbearing Computed Tomography Scan.

UNLABELLED

Müller-Weiss disease (MWD) is a rare condition that results in dorsolateral collapse of the navicular associated with rotation of the talar head and subtalar varus deformity. There are also varying degrees of midfoot collapse and associated loss of the medial arch in more advanced cases. The characteristic deformities and classification have been described on weightbearing radiographs. While early stage disease can be detected on magnetic resonance imaging and bone scan, there are considerable advantages to computed tomography (CT) scanning, in particular, weightbearing CT for further evaluation of this condition. We describe the imaging findings of this condition, and present 3 cases where weightbearing CT was used in the context of MWD. This is the first time the use of weightbearing CT scan has been reported for diagnosis and treatment of this condition.
