OSTEOMYELITIS
,INTRODUCTION
Nelaton (1834) : coined osteomyelitis
The root words:
osteon (bone) and
myelo (marrow) are combined with
itis (inflammation) to define the clinical state
in which bone is infected with microorganisms
It may remain localized, or it may spread
through the bone to involve the marrow,
cortex, periosteum, and soft tissue
surrounding the bone.
,DEFINATION
Osteomyelitis is defined as an acute or
chronic inflammatory process of bone, bone
marrow and its structure secondary to
infection with micro organisms
, CLASSIFICATION
Duration –
Acute (<2 weeks)
Subacute (2-6 weeks)
Chronic (>6 weeks)
Mechanism –
Heamatogenous (tonsil , lungs , ear/ GIT) –
Exogenous (surgery/iatrogenic , open fractures)
Host response –
Pyogenic
Non-Pyogenic/Granulomatous
