Haematogen osteomyelitis is mostly found in children and adolescents.
In western Europe acute haematogen osteomyelitis (AHOM) is a rare dise
ase. This is the cause why AHOM is often diagnosed with delay. The tre
atment usually is an antibiotic medication and/or surgical interventio
ns. Uncharacteristic pain of extremities in children should always con
sider the diagnosis of acute osteomyelitis. Investigation should inclu
de conventional Xrays, ultrasounds or MRI to prevent the spreading of
infection. In cases of multifocale infection radionuclide imaging shou
ld be undergone. Differential diagnosis should always include malignan
t tumor. If under treatment of antibiotics the clinical signs of illne
ss do not decrease within 24 h surgery with fenestration of the involv
ed bone, debridement and local application of antibiotics is indicated
. In unusual cases or in cases with clinical signs of AHOM but no bact
eria specification a malignant tumor has to be excluded.
