Summary
Tertiary syphilis spinal lesions causing cauda equina compression are rare and difficult to diagnose. Surgical intervention may aid neuropathy but carries risks like Charcot
Area of Science:
- Neurology
- Orthopedic Surgery
- Infectious Diseases
Background:
- Tertiary syphilis spinal involvement with destructive bone lesions is exceptionally rare.
- Diagnosis is challenging, often requiring more than radiographic and histological analysis.
- Limited data exist on surgical interventions for syphilitic spinal lesions.
Observation:
- A 44-year-old male presented with chronic low back pain and acute radiating lower extremity pain.
- Radiological findings revealed osteolytic lesions and new bone formation in L4-L5 vertebral bodies.
- Positive serum Treponema pallidum hemagglutination (TPHA) confirmed syphilis.
Findings:
- Surgical debridement, fusion, and instrumentation were performed for cauda equina compression.
- Postoperative low back pain and numbness improved, but graft absorption and instrumentation failure occurred.
- Development of Charcot's arthropathy between L4 and L5 was noted as a complication.
Implications:
- Diagnosing spinal tertiary syphilis remains a significant clinical challenge.
- Surgery can be a valuable adjunct to antibiotic therapy for syphilitic spinal neuropathy.
- Charcot's arthropathy is a potential complication following surgical treatment.
