Applied anatomy of cervical nerve root groove and cervical intervertebral foramen

Objective : To obtain the quantitative data for pathogeny, diagnosis and treatment of the cervical spondylosis. Methods : The cervical nerve groove was measured on the dried cervical vertebra specimens and the cervical intervertebral foramen was measured on the fixed cervical vertebra cadaveric specimens with formalin. Results : The average length of the medial zone and distances from the midpoint of the anterior border of the medial zone to the midline of the vertebral body consistently increased from C3 to C7. The width of the medial zone of C3 was larger. The smallest anteroposterior distances from the posterior midpoint of the summation of the high of the superior and inferior articular process to the posterior border of the nerve root groove were found in C7. Conclusion : This study provide important anatomy data for surgical operation and eikonic diagnosis.
