Summary
This study discusses C-1 cord compression in adults due to a hypoplastic atlas, a rare condition causing spinal cord issues. Posterior decompression is the recommended treatment for this condition.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Spinal cord compression can arise from various etiologies, including congenital anomalies.
- A hypoplastic atlas (first cervical vertebra) can lead to significant neurological compromise.
Observation:
- A case of a 66-year-old man with progressive, nontraumatic C-1 cord compression due to a hypoplastic atlas is presented.
- Literature review identified six similar cases, with symptom onset typically in late adulthood.
Findings:
- Patients often present with a narrow sagittal canal diameter (≤10 mm).
- Surgical intervention, specifically posterior decompression, is the standard treatment.
- Dural opening may be required during surgery.
Implications:
- Early diagnosis and surgical decompression are crucial for managing C-1 cord compression.
- While stabilization is sometimes considered, it's not always a primary necessity.
- Understanding this rare condition aids in better patient outcomes and surgical planning.
