Rashmi Bhardwaj, Vivek Parashar, Himanshu Joshi, Shital Hathila

Introduction: Inappropriate fusion of adjacent vertebrae results in Block vertebrae or Spinal fusion or vertebral synostosis. It can occur at any vertebral levels from cervical to Sacral.Vertebral synostoses are of interest not only to anatomists but also to radiologists, orthopaedicians, neurologists, forensic pathologist etc. Our aim is to find out the incidence of cervical vertebral synostosis at different levels in cervical region. Methods: The present study was conducted on 40 dried adult vertebral columnsand 150 dry specimens of assorted cervical vertebrae obtained from the Anatomy department of Medical College Baroda,Vadodara, Gujarat &TeerthankerMahaveer Medical College, Moradabad. The vertebrae of the cervicalregions were studied to see if there is any abnormal fusion between contiguous vertebral bodies, pedicles, laminae, spines or transverse processes. Results & Observation: In the present study, two different types of fused Cervical vertebrae were identified. Assimilation of Atlas: Fusion of atlas with occipital bone of Skull and Cervical Vertebral Synostosis at C2-C3 Vertebral level. The features of these block vertebrae were analyzed in detail and photographed from different aspects.The Phylogenetic, embryological, clinical implication and incidences of such synostosis as reported by various authors have been discussed in this paper. Conclusion: The block vertebrae in cervical regions of vertebral column can lead to a variety of symptoms or may be asymptomatic, depending upon the degree of compression exerted by them on adjoining structures like spinal nerves, blood vessels or spinal cord. It may cause restricted movements, premature degenerative changes and associated neurological and musculoskeletal abnormalities.
