Pathohistological features of foci of traumatic osteomyelitis and some clinical and morphological parallels

Histologic examination of the structure of traumatic osteomyelitic foci in acute and chronic stages, types of bone tissue lesions was performed in experimental morphologic and clinical biopsy material. Differences in various inflammatory changes rates in patients groups were statistically determined. In chronic stage the osteomyelitic focus showed centrally located necrosis and exudate surrounded by internal, fibrous and osseous membranes of the focus capsule. Lesions of bone tissue were heterogenic and stipulated not only by inflammatory process but the ischemic effect as well: osteonecroses, purulent osteonecroses, complete and incomplete sequesters should be differentiated in the affected bone. The rate of various types of inflammation within the internal membrane of focus capsule was reliably different depending on the term of osteomyelitic process (inflammation of high activity was more common under 1 year) and on the fragments fixation method (inflammation of high activity was more often noted in metallosteosynthesis).
