[The value of computerized tomography in assessing chronic osteomyelitis].

Computed tomography (CT) creates cross sectional images with the benefit of high density and contrast resolution. In a retrospective study we have assessed the value of CT investigation of 23 patients with chronic osteomyelitis of the lower limb by comparing the findings with the plain radiographs, the surgical records and the histology of specific areas. We were able to establish that CT provides an excellent assessment of the bone and soft tissue structures as well as providing a precise localisation of the process. Sequestra, periosteal and endosteal bone proliferation, sinus, scar tissue and abscesses can be clearly identified. A rough evaluation of the bone vitality can also be made. In cases of chronic osteomyelitis without metal implants CT studies, together with clinical records and plain radiographs are able to establish the better operative approach and so optimise the indication for operation.
