Summary
Rare bone regrowth after lumbar surgery caused severe spinal canal restenosis and neurological symptoms in two patients. Further surgical intervention was required to alleviate symptoms and manage bone overgrowth.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Orthopedic Surgery
Background:
- Lumbar decompression and fusion surgeries are common procedures for spinal stenosis and fractures.
- Post-operative bone regrowth can occur, but typically does not cause significant complications.
Observation:
- Two patients developed severe spinal canal restenosis due to excessive bone regrowth years after initial lumbar decompression and fusion.
- Symptoms included lower back pain and neurological deficits, necessitating further surgical intervention.
Findings:
- The first patient experienced restenosis 5 years post-surgery due to unilateral bone overgrowth, requiring revision surgery.
- The second patient developed bilateral bone overgrowth 1 year after a second surgery for a burst fracture, leading to a third surgical procedure.
Implications:
- Excessive bone regrowth can lead to delayed neurological complications after lumbar fusion.
- Understanding factors influencing bone regrowth is crucial for preventing restenosis.
- Revision surgeries may be necessary to manage symptomatic bone overgrowth and restore spinal canal patency.
