Prosthetic hip joint infection caused by non-capsulated Haemophilus influenzae

Area of Science:

• Orthopedic surgery
• Infectious diseases
• Microbiology

Background:

• Prosthetic joint infections (PJIs) are serious complications following joint replacement surgery.
• Haemophilus influenzae is an uncommon pathogen in PJIs, typically associated with other infections.
• Early diagnosis and appropriate treatment are crucial for successful PJI management and implant survival.

Observation:

• A case of prosthetic hip joint infection is presented.
• The causative agent was identified as Haemophilus influenzae.
• The patient presented with symptoms indicative of a deep joint infection.

Findings:

• Surgical debridement was performed to remove infected tissue and debris.
• Antibiotic therapy was initiated with ciprofloxacin as monotherapy.
• Treatment duration was 3 months, leading to successful infection eradication.

Implications:

• This case highlights Haemophilus influenzae as a potential pathogen in prosthetic joint infections.
• Successful implant salvage is achievable with prompt surgical intervention and targeted antibiotic therapy.
• Ciprofloxacin monotherapy may be a viable treatment option for specific cases of H. influenzae PJI.
