Diagnosis depends on the fracture type:

• Dorsal avulsion fractures are usually easily diagnosed on lateral radiographs of the foot.
• Tuberosity fractures can be more difficult to diagnose; most have minimal or no displacement and are not apparent on standard foot films. In patients with bony pain below the medial malleolus, order a reverse oblique view in addition to standard views to better visualize the navicular tuberosity.
• Body fractures are usually diagnosed on standard foot films. CT may be necessary for fracture definition and operative planning.
• Stress fractures are typically not apparent on x-ray and require bone scan or MRI (usually as outpatient) for diagnosis.
