Abstract：Objective: To measure foramen intervertebrale of adults’ lumbar segments by spiral CT volume rendering and to analyze the differences and changing tendency between lumbar foramen intervertebrale. Method: The lumbar foramen intervertebrale of 120 subjects without lumbar disease were analysed using spiral CT by volume rendering(VR). The superoinferior diameter and anteroposterior diameter of foramen intervertebrale were measured and compared between different sex and age groups. Result: For superoinferior diameter of foramen intervertebrale, there were no significant differences between male and female (P>0.05) but significant differences between different lumbar segments or different age groups(P＜0.05). For anteroposterior diameter of foramen intervertebrale, there were no significant differences between male and female or different age groups(P>0.05). But there were significant differences between different lumbar segments(P＜0.05). Conlusion: The superoinferior diameter and anteroposterior diameter of foramen intervertebrale vary from different lumbar segments, which provides reference to bone tunnels before transforaminal endoscopy operation or interventional treatment.
