Basing on their own experience in the diagnosis and treatment of children with hematogenous osteomyelitis and their study of domestic and foreign sources, the authors came to the conclusion that in all classifications available, consensus is lacking on the origin, course, form, stage, phase, outcome, and consequences of hematogenous osteomyelitis in children. This realization prompted us to revise the classification of hematogenous osteomyelitis in children.

The proposed new classification of hematogenous osteomyelitis in children was developed by amending the existing ones. It consists of 10 headings: etiology, origin, course, form, stages, localization, morphological form, complications, outcome, and consequences. Along the course, hematogenous osteomyelitis was divided into acute, subacute, and atypical forms. In addition to the allocation of “subacute” hematogenous osteomyelitis, a separate section gives a brief description of the features of its course and clinical manifestations. Hematogenous osteomyelitis of bones forming joints and hematogenous osteomyelitis of mixed bones (spine) were added to the “Localization” section, and apophyseal localization was added to osteomyelitis of tubular bones. In the “Outcome” section in the “Recovery” section, four subsections were highlighted.

We submit this classification for discussion and await opinions and suggestions from pediatric surgeons on improving the classification of hematogenous osteomyelitis in children.
