C1-2 Stenosis Caused by Posterior Osteophytes: An Unusual Cause of Cord Compression.

Cervical spinal stenosis most commonly occurs at the subaxial spine. C1-C2 stenosis is relatively unusual but can be present in certain congenital or syndromic conditions such as rheumatoid arthritis. In this manuscript, we highlight the case of a 42-year-old lady who presented with neck pain and signs of high cervical myelopathy. Imaging studies showed severe stenosis at C1-C2 caused by posterior osteophytes originating from the C1 arch and C2 lamina. Decompression and stabilization of the segment were performed. This case is unique as this pathology occurred at an uncommon location, leading to an unusual degree of compression and resulting in surgical intervention.
