The value of scintigraphy in the early detection of osteomyelitis is demonstrated in children who had signs and symptoms suggestive of bone infection. Nine patients between 2 and 13 years of age were evaluated with technetium Tc 99m diphosphonate bone scintigrams and roentgenograms. Blood cultures were performed in all patients, and bone biopsy or drainage was obtained in six patients. The diagnosis of osteomyelitis was made in seven patients; one patient had a subperiosteal abscess surrounded by osteomyelitis, and one patient had cellulitis. The seven children with osteomyelitis had focal increase of radiopharmaceutical uptake in the bone. The child with the subperiosteal abscess had an area of decreased uptake in the center of the abscess surrounded by a zone of increased uptake of the radioactive bone-seeker. The patient with cellulitis had soft tissue changes by X-ray and a normal bone scintigram. In the seven patients with osteomyelitis, the bone scintigram was performed during the early phase of the disease and no bony changes were present on the roentgenogram. In one patient with subacute osteomyelitis, soft tissue changes were seen radiologically. Only three of the seven children with osteomyelitis developed radiological bony changes. Since bone scintigraphy can detect early local bone derangement, it is recommended in the initial evaluation of children in whom osteomyelitis is suspected.
