Assessing the limping child with skeletal scintigraphy.

Skeletal scintigraphy is frequently used in the clinical investigation of young children who present with limping as their only or predominant symptom. This article reviews techniques used for pediatric skeletal scintigraphy, skeletal tracer distribution in the immature skeleton and scintigraphic manifestations of relatively common conditions that can produce limping in children 1-6 yr old. Acute osteomyelitis, vertebral infections, transient synovitis, septic arthritis, Legg-Calvé-Perthes disease, lower extremity injuries in toddlers and osteoid osteoma are emphasized.
