To identify anterior spinal artery (ASA) infarct or occlusion by CT angiography (CTA) in patients with cervical spondylotic myelopathy (CSM). ⋯ ASA infarct or occlusion is not commonly seen in CSM patients with spinal canal sagittal diameter compression less than 80%. Pathological changes about T2-weighted hyperintensity of MR image in CSM have no close correlation with ASA infarct.

To characterize in vivo the transpedicular approach (TA) as an alternative route to study intervertebral disc (IVD) regeneration strategies in a sheep model. ⋯ TA is feasible in vivo, repeatable after only a short learning period and safely performed without significant morbidity. This animal model allows the study of IVD degeneration physiopathology and investigation of IVD regeneration techniques in vivo.
