Haemophilus septic arthritis

Haemophilus septic arthritis is an acute, purulent joint infection caused by bacteria of the genus *Haemophilus*, most frequently *Haemophilus influenzae* Primarily affecting the synovial fluid and articular tissues of large joints—such as the knee, hip, or elbow—it historically presented most often in infants and unimmunized young children, but it also occurs in adults with underlying immunocompromising conditions, complement deficiencies, or pre-existing arthropathies

Pathophysiologically, the bacteria seed the joint space via hematogenous dissemination from an initial respiratory tract focus or occult bacteremia, provoking intense neutrophilic inflammation that leads to joint effusion, synovial ischemia, and potential cartilage destruction Defining clinical manifestations include acute-onset fever, severe joint pain, swelling, erythema, and markedly restricted range of motion, typically characterized by purulent synovial fluid exhibiting pleomorphic gram-neg...
