|January 1, 1997
Summary
Previously quiescent osteomyelitis can present as septic arthritis. Prompt diagnosis and aggressive treatment including surgical debridement and antibiotics are crucial for resolution.
Area of Science:
- Orthopedics
- Infectious Diseases
- Radiology
Background:
- Osteomyelitis is a bone infection that can remain dormant.
- Septic arthritis is a joint infection.
- Adjacent joint involvement can mask underlying osteomyelitis.
Observation:
- Four cases of quiescent osteomyelitis presented as septic arthritis in an adjacent joint.
- The osteomyelitic focus was located proximally (0-10 cm) above the joint line.
- Low-grade joint sepsis caused diagnostic and treatment delays.
Findings:
- Aggressive surgical debridement of both bone and joint was performed.
- Patients received a prolonged course of antibiotics.
- All patients achieved resolution of their condition.
Implications:
- A high index of suspicion is necessary for diagnosing this condition.
- Adequate radiographs of surrounding bones are essential for diagnosis.
- Early and comprehensive treatment leads to successful outcomes.
