|November 1, 1985
Summary
Large, old lumbar herniated disks can cause bone changes like erosion and enlargement. These osseous changes indicate significant disc degeneration and potential nerve compression.
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Radiology
Background:
- Lumbar herniated disks are a common cause of low back pain.
- Large and chronic herniated disks may lead to secondary osseous changes.
Observation:
- Four patients with large, old lumbar herniated disks were studied.
- Radiographic evidence of specific bone alterations was noted.
Findings:
- Observed osseous changes include posterior vertebral body cortex erosion near the herniated disk.
- Enlargement of the spinal canal and intervertebral foramen was documented.
- Focal sclerosis of the adjacent vertebral body was present.
Implications:
- These findings highlight potential bony remodeling secondary to chronic disc pathology.
- Understanding these changes is crucial for accurate diagnosis and surgical planning.
- Further research can explore the clinical significance and progression of these osseous alterations.
