High Cervical and Lumbar Canal Stenosis of Varied Etiology : A Case Report

Developmental stenosis without any significant spondylotic changes frequently occurs at C3 vertebra or below, and typically extends to C6-C7. However, high cervical focal canal stenosis is unusual. A case of cervical canal segmental stenosis at C2-3 level in addition to a developmental stenosis of the lumbar region, in a 45 year old male, has been presented in this article. The dynamics of the spinal canal in relation to the likely pathology of such conditions are reviewed. We speculate that focal segmental stenosis in the high cervical region may be due to a possible premature fusion of the neurocentral synchondrosis of the cartilage, or due to an abnormal rotary biomechanics which can result in facetal hypertrophy.
