【摘要】：目的:探讨正常国人椎管内硬膜外背侧脂肪含量的相关影响因素。方法:在MRI正中矢状面图像上统计263例正常国人腰段椎管硬膜外背侧脂肪厚度,计算其中120例相应层面椎管前后径,同时计算其中50例的体重指数。将263例分为青壮年组(18~59岁,207例)和老年组(≥60岁,56例);腰椎生理弯曲度分为三级,即明显变直、轻度变直和正常曲度。结果:腰段硬膜外各节段背侧脂肪含量均与体重指数、椎管前后径及生理弯曲度呈正相关;老年组L3/4节段硬膜外背侧脂肪含量厚度小于青壮年组,其余节段两组间差异无统计学意义(P0.05);不同性别间硬膜外背侧脂肪厚度差异无统计学意义(P0.05)。结论:正常国人腰段椎管内硬膜外背侧脂肪含量与体重指数、椎管前后径及腰椎生理弯曲度相关,与年龄、性别无相关性。
[Abstract]:Objective: to investigate the related factors influencing the dorsal fat content of epidural spinal canal in normal Chinese. Methods: the thickness of dorsal fat in lumbar spinal canal of 263 normal Chinese was counted on MRI median sagittal plane. Among them, 120 cases were calculated for the anteroposterior diameter of the vertebral canal at the corresponding level, and 50 cases were calculated for body mass index. 263 cases were divided into two groups: the young group (207 cases) and the elderly group (56 cases 鈮，
