Imaging Studies
- X-rays (see Image 1)
- The lateral view shows a flat tarsal scaphoid (see Image 2)
- The space between the talus and the cuneiforms is not decreased.
- Frequently, there is an irregular ossification of the tarsal navicular bone or radiologic changes that resemble Köhler disease, but the diagnosis must not be made in the absence of clinical signs.5,6
- Bone scanning
- Bone scans reveal a decreased uptake of radionuclide in the right midtarsal area.7
- This exam is not necessary for the diagnosis.
- If pain persists 6 months after casting, a magnetic resonance image (MRI) study or computed tomography (CT) scanning is necessary to exclude a tarsal coalition.8
Radiograph from a 16-year-old patient who had Köhler disease. Normal x-rays at adulthood are the rule for Köhler disease.
Radiograph from a patient with Köhler disease. This image is typical for Köhler disease. Note the flat aspect of the tarsal scaphoid.
