Summary
This study presents the first case of spinal pseudarthrosis in ochronosis, demonstrating posterior-only 360° surgery for ankylosed spine fusion. This approach offers an effective alternative for managing spinal pseudarthrosis.
Area of Science:
- Spine surgery
- Orthopedics
- Medical case study
Background:
- Spinal involvement in ochronosis leads to reduced flexibility and ankylosis.
- Pseudarthrosis is a known complication of ankylosing spinal conditions.
- The occurrence of pseudarthrosis in ochronosis has not been previously documented.
Observation:
- A 68-year-old male with ochronosis presented with progressive paraparesis.
- Imaging revealed pseudarthrosis at the T11-T12 level.
- The patient underwent a posterior-only 360° surgical approach.
Findings:
- The surgery included circumferential decompression, debridement, interbody fusion, and screw-rod fixation.
- Postoperatively, the patient showed significant improvement in pain and neurological function.
- At 3 months, the patient could walk independently.
Implications:
- Ochronosis should be considered an etiology for spinal pseudarthrosis.
- Suspect pseudarthrosis in patients with ankylosing diseases experiencing worsening back pain or neurological deficits.
- Posterior-only 360° surgery may be a viable alternative to combined anterior-posterior approaches for spinal pseudarthrosis.
