Abstract
The authors reviewed the three-phase bone scans and radiographs of 24 patients with suspected pedal osteomyelitis who also had histologic confirmation of the diagnosis. Twenty patients had a pedal ulcer, cellulitis, or necrosis. Sensitivity and specificity of bone scanning were 70% and 43% respectively. Sensitivity and specificity of radiography were 70% and 50% respectively. The non-invasive diagnosis of pedal osteomyelitis remains problematic due to the poor specificity of bone scans and radiographs.
