The relationship of isotopic bone imaging findings to prognosis in Legg-Perthes disease.
A significant association was observed between the size of the radioactive uptake defect on bone image and the end-result (Mose) in 34 hips of children with early Legg-Perthes disease. A correlation between the size of the bone-image defect and radiographic prognostic criteria, Catterall classification and extent of subchondral fissure was also observed in 27 early Legg-Perthes cases. Bone imaging is recommended for suspected Legg-Perthes patients, not only to establish the diagnosis but to assess the stage of disease and to determine prognosis.
