Primary subacute osteomyelitis of the greater trochanter.

Abstract

Primary subacute osteomyelitis is difficult to diagnose, because of its insidious onset, mild symptoms, lack of a systemic reaction, and similarity with tumoral conditions. This condition is seen mostly in the epiphysis or metaphysis of tibia. Although it has been reported at various bones, its occurrence in the greater trochanter is rare. We describe two patients, 4 and 14 years old, with mild pain of the hip joint and limping without history of acute bone infection. Radiography showed a lytic lesion in the greater trochanter resembling Brodie abscess. Both patients were treated completely with antibiotics.
