Effects of occipital-atlas stabilization in the upper cervical spine kinematics: an in vitro study [PDF]
Scientific Reports, 2021 AbstractThis study compares upper cervical spine range of motion (ROM) in the three cardinal planes before and after occiput-atlas (C0–C1) stabilization. After the dissection of the superficial structures to the alar ligament and the fixation of C2, ten cryopreserved upper cervical columns were manually mobilized in the three cardinal planes of ...

Cervical cord compression by solitary osteochondroma of the atlas. [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1978 A 28 year old woman presented a syndrome of slow spinal compression evolving over four and a half years at the level C1--C2 vertebrae due to a solitary osteochondroma of the posterior arch of the atlas which was excised by laminectomy. Radiographys of the skeleton did not show the presence of other osteogenic tumours. This is the fifth case of solitary
