Abstract
Septic arthritis is an infection to one joint or more that mainly happens after a hematogenous
spread of an infection causing inflammation to the joint. Large joints such as hip and knee
are more commonly affected, however, septic arthritis can happen in any other joints such
as shoulders and ankles. Staphylococcus aureus is the most frequently isolated pathogen
in this condition; however, other bacteria, viruses, fungi, and mycobacterium can also
cause septic arthritis. Haemophilus influenzae type b (Hib) is the most common subtype
of Haemophilus influenza and is primarily affecting children and those with compromised
immune systems. Haemophilus influenza usually causes lower respiratory tract infections,
including pneumonia. In addition, they can induce numerous other severe infections, such
as bacteremia, empyema, meningitis, cellulitis, and septic arthritis.
The Hib conjugate vaccine has significantly reduced the incidence of Hib infections and
is effective in protecting against capsular polysaccharide type b. the CDC recommends
administering a conjugate Hib vaccine series beginning at age 2 months, or 6 weeks followed
by boosters at age of12 to 15 months. In this article, we are reporting a unique case of hip
septic joint in a fully vaccinated teenager, and it is the first case reported in the literature
to our knowledge.
