Occipitalisation of atlas is an osseous anomaly in the region of the foramen magnum.1 This is important as skeletal abnormalities at this junction may result in sudden death.1,2
Material & Methods: During routine undergraduate osteology teaching, a dry skull with Occipitalisation of atlas was encountered in the department of Anatomy, nri medical college, mangalgiri, India.
Results: In this skull, both anterior and posterior arch along with transverse process of both sides of atlas were completely fused with occipital bone. Reduction in diameter of foramen magnum due to this condition can cause neurological complications due to compression of spinal cord or medulla oblongata, vertebral vessels, 1st cervical nerve, this knowledge of occipitalisation of the atlas is important toorthopaedicians, neurosurgeons, physicians and radiologists dealing with abnormalities of the cervical spine.
