Abstract


Background: The morphometery of the cervical spine vertebra is of clinical importance in traumatic, degenerative and inflammatory condition requiring surgery and instrumentation. The aim of this study was to determine the mid-sagittal, AP Transverse diameter, AP diameter of cervical vertebral body, surface area of canal and torg ratio at level C2 –C7.

Methods: Study was performed in the department of general surgery, GMC and Hamidia Hospital Bhopal from January 2016 - June 2020 in 300 patients with clinically apparent cervical spondylosis and cervical spine injury belongs to central India of age group 20- 88 years including males and females by gathering their parameters (height and weight) and CT of cervical region from C1 to D1 spine.

Results: In our study maximum sagittal canal diameter in males was found at C2 vertebral level (14.14 mm) and minimum at C4 vertebral level (14.00 mm) whereas the maximum sagittal canal diameter in females was found at C2 and C7 vertebral level (14.00 mm) and minimum at C4 vertebral level (13.82 mm) while mean sagittal canal diameter was greater in males than females. The maximum transverse canal diameter in both males and female was found at C7 level, it measures 21.09 mm in males and 21.38 mm in females.

Conclusions: The CT scan can provide accurate cervical canal measurement that could serve as useful guide in preoperative surgical planning, instrumentation and size of prosthesis.
