【摘要】：目的:探討正常國(guó)人椎管內(nèi)硬膜外背側(cè)脂肪含量的相關(guān)影響因素。方法:在MRI正中矢狀面圖像上統(tǒng)計(jì)263例正常國(guó)人腰段椎管硬膜外背側(cè)脂肪厚度,計(jì)算其中120例相應(yīng)層面椎管前后徑,同時(shí)計(jì)算其中50例的體重指數(shù)。將263例分為青壯年組(18~59歲,207例)和老年組(≥60歲,56例);腰椎生理彎曲度分為三級(jí),即明顯變直、輕度變直和正常曲度。結(jié)果:腰段硬膜外各節(jié)段背側(cè)脂肪含量均與體重指數(shù)、椎管前后徑及生理彎曲度呈正相關(guān);老年組L3/4節(jié)段硬膜外背側(cè)脂肪含量厚度小于青壯年組,其余節(jié)段兩組間差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05);不同性別間硬膜外背側(cè)脂肪厚度差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論:正常國(guó)人腰段椎管內(nèi)硬膜外背側(cè)脂肪含量與體重指數(shù)、椎管前后徑及腰椎生理彎曲度相關(guān),與年齡、性別無(wú)相關(guān)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，
