title: [Brodie abscess. Primarily misinterpreted as traumatic lesion].
abstract: Two case histories are presented. In the first, a 49 year-old man fell on his right hip. He was able to walk, but because of pain he came to our emergency room. Radiographics gave an impression of an undislocated intertrochanteric fracture, scintigraphy confirmed the suspicion. There were no signs of infection. On starting osteosynthesis with the drilling of a hole in the lateral cortex, discharge of pus was observed and curettage of the abscess cavity was performed. In the second, a 21 year-old man hit his right knee against a table. Because of pain he was admitted to hospital. Primary signs of a lesion of the lateral meniscus were found and arthroscopy was scheduled. When readmitted we found signs of an infection and X-ray revealed a Brodie's abscess in the proximal tibia. The abscess cavity was opened and curettage was performed. Radiographics, scintigraphics, blood parameters and pathological and microbiological investigations revealed primary chronic osteomyelitis in both patients. Antibiotic therapy was instituted and six weeks after primary operation bone transplantation was performed. The further course was uncomplicated.
