Skeletal abnormalities of cervical region or in craniocervical region are of interest to the anatomists, orthopaedicians, neurologists, neurosurgeons and even orthodontists. These abnormalities may result in severe neck pain, decreased neck mobility, muscular weakness and sensory deficits of both upper limbs and sudden unexpected death. During the routine osteology teaching, it was observed that the axis vertebra is fused with the third cervical vertebra. It was observed that body, laminae and pedicles of C2 and C3 were completely fused on both anterior and posterior aspects. The features of these fused cervical vertebrae were analysed and the specimen was photographed from different aspects. This is a condition of block vertebra which has embryological importance and clinical implications.
