Müller-Weiss disease: Four case reports

Table 2 Radiological staging by Maceira and Rochera[5]

Radiological staging
Stage 1	Normal or minimal bone changes on radiographs. Subtle subtalar varus. Intra-osseus edema on MRI. Positive CT scan
Stage 2	Initial cavovarus: Subtalar varus and dorsal angulation of Meary’s line, dorsal and lateral subluxation of the talar head
Stage 3	Subtalar varus. Medial column shortened. Neutral Meary’s line
Stage 4	Subtalar varus. Plantarwards Meary’s line. Paradoxical pes planus with varus and calcaneal equinus
Stage 5	Degeneration of the subtalar joint. Formation of talo-cuneiform articulation, complete extrusion of the navicular

MRI: Magnetic resonance imaging; CT: Computed tomography.
