The Bone
  • Definition

4
Bacterial Infection of Bone
  • Origin of Bone Infections
  • Microorganisms introduced during injury
  • Microorganisms from the blood stream

5
Bacterial Infection of Bone
  • Origin of Bone Infections
  • Microorganisms introduced during operative
    procedures

6
Bacterial Infection of Bone
  • Origin of Bone Infections
  • Microorganisms from the blood stream

7
Bacterial Infection of Bone
  • Actions of Microorganisms Localized in Bone
  • Proliferate

8
Bacterial Infection of Bone
  • Actions of Microorganisms Localized in Bone
  • Produce cell death

9
Bacterial Infection of Bone
  • Actions of Microorganisms Localized in Bone
  • Spread within the bone shaft

10
Bacterial Infection of Bone
  • Actions of Microorganisms Localized in Bone
  • Incite a chronic inflammatory response with
    further destruction of bone

11
Bacterial Infection of Bone
  • Actions of Microorganisms Localized in Bone

12
Types of Bacterial Infection of Bone
  • 1. Osteomyelitis

13
Types of Bacterial Infection of Bone
  • Types of Osteomyelitis
  • 1. Hematogenous Osteomyelitis
  • Originates with infectious organisms that reach
    the bone through the blood stream

14
Types of Bacterial Infection of Bone
  • Types of Osteomyelitis
  • 2. Contiguous Spread Osteomyelitis
  • Secondary to a contiguous focus of infection
  • Direct inoculation from an exogenous source or
    from an adjacent extraskeletal site

15
Types of Bacterial Infection of Bone
  • Types of Osteomyelitis
  • Chronic Osteomyelitis
  • Occur secondary to an open wound

16
Bacterial Infection of Bone
  • Prevention of Bone Infection
  • Careful cleaning and debridement of skeletal
    injuries

17
  • Prevention of Bone Infection
  • 2. Strict operating room protocols
