OPEN (COMPOUND) FRACTURES

An open fracture can be defined as a broken bone that is in communication through the skin with the environment.

Open fractures are much like pregnancy: they either are or they are not.

PRINCIPLES OF TREATMENT 1. Open injuries to bones and joints should be treated as emergencies. 2. The patient should be evaluated carefully to diagnose other life-threatening injuries. 3. Appropriate and adequate systemic antibiotic therapy should begin immediately. 4. The wound should be thoroughly debrided and cleansed. 5. The fracture or joint injury should be stabilized; cancellous bone grafting can be performed immediately or can be delayed. 6. The wound should be appropriately dressed or closed; measures should be taken to facilitate wound drainage. 7. The limb and patient should undergo rehabilitation.

OSTEOMYELITIS

OSTEOMYELITIS IS AN INFECTION OF BONE, BONE MARROW AND SURROUNDED SOFT TISSUES

Cause  S. Aureus S. Aureus  Enterobacter Enterobacter  Streptococcus Streptococcus

Pathogenesis Microorganisms may infect bone through one or more of three basic methods: via the bloodstream, contiguously from local areas of infection (as in cellulitis),bloodstream cellulitis penetrating trauma, including iatrogenic causes such as joint replacements or internal fixation of fracturestraumaiatrogenicjoint replacements fractures root-canaled teeth root-canaled
