Abstract

Introduction: cervical vertebrae are the upper most vertebrae in vertebral column. They are more prone to damage during road traffic accidents. Their dimensions are important  for various  spinal  surgical  procedures  to access the spinal cord for decompression  procedures.

Aim and Objective: Variations in the dimensions of sub axial vertebrae is of very important for spinal surgical procedures like Transpedicular screwing, Laminectomy, Foraminectomy, Transcorporeal Micro decompression surgery. The present study was done in the C3–C7 vertebrae of south Indians to know the Mean values of various dimensions of sub axial vertebrae.

Materials and Methods: The present study was done in 60 sub axial vertebrae, which were done in Rajah Muthiah Medical College, Chidambaram. Dimensions of Body (Antero posterior Length, Transverse Length & Height), Pedicle (Height, Length & Width), Lamina (Length, width & Height), Foramen Transversorium (Antero posterior Diameter, Transverse Diameter), Spinous process (Length) were studied.

Main outcome measure:  Variations in the dimensions of body, pedicle, lamina, Spinous process, Foramen transversorium were observed.

Result:  The Mean values of dimensions of vertebral body, lamina, pedicle, Foramen Transversorium & Spinous process were measured. Dimensions of body was maximum at C6 level. Length of pedicle was maximum at C3, Minimum at C6. Height & width of pedicle gradually increase from C3 to C7. Height of Lamina was maximum at C6, Length & width of Laminae was gradually increases from C3 to C7.

Conclusion:  This study will provide the knowledge about dimensions of sub axial vertebrae in South Indian population.  This will be helpful for spinal Surgeries & Radiological Interpretations.

Key words: Sub axial cervical vertebrae, Transpedicular fixation, Laminectomy, Foramenectomy.
