Summary
A rare case of osteoarticular tuberculosis developed in a 72-year-old woman after hip surgery. Treatment involved implant removal, hip resection, and arthroplasty, highlighting potential infection pathways.
Area of Science:
- Orthopedic Surgery
- Infectious Diseases
- Tuberculosis Research
Background:
- Osteoarticular tuberculosis is uncommon, particularly following orthopedic procedures.
- Pertrochanteric fractures often require surgical fixation with implants like dynamic hip screws.
Observation:
- A 72-year-old woman presented with osteoarticular tuberculosis post-dynamic hip screw surgery for a pertrochanteric fracture.
- The patient exhibited femoral head necrosis and prosthetic material disassembly.
- No prior history of pulmonary or extra-pulmonary tuberculosis was noted.
Findings:
- Diagnosis was confirmed via pathological findings.
- Successful treatment involved surgical intervention (implant ablation, head-neck resection, total hip arthroplasty) and antibiotic therapy.
Implications:
- This case suggests potential hematogenous dissemination or reactivation of latent infection as pathogenic mechanisms.
- Highlights the importance of considering tuberculosis in unexplained osteomyelitis post-surgery.
- Informs surgical and infectious disease management strategies for prosthetic joint infections.
