Infective Arthritis

BONE & JOINT DISORDERS (ARTHRITIS)

INFECTIVE OR SEPTIC ARTHRITIS – INTRODUCTION

Infective arthritis is a joint disease caused by any infectious agent. Bacterial arthritis is the most destructive form of infectious arthritis. The onset is acute with symptoms of septicemia. The major organisms responsible are Neisseria gonorrhea and staphylococcus aureus. The source of infection is:

  • Spread through blood : This usually occurs secondary to puncture wound, skin infection or acute osteomyelitis (usually a bacterial infection of bone and bone marrow).
  • Intravenous drug use : This causes infection in unusual joints like sternoclavicular joint (joint between chest bone and collar bone) and sacro-iliac joint (hip joint). These infections are frequently secondary to organism like Pseudomonas, Serratia.
  • Underlying illness : Use of steroids, presence of artificial joint, rheumatoid arthritis and diabetes increase the risk of infection.
