隐性脊柱裂(spina bifida occulta,SBO)是指有一个或数个椎骨的椎板闭合不全,脊柱背侧皮肤完整,椎管内的脊髓及神经组织不会直接突出于皮肤表面的脊柱裂.SBO可发生于脊柱任何部位,但常发生于腰骶部,可伴有脊髓神经发育畸形,产生神经系统、泌尿系统、消化系统以及运动系统等一系列临床症状和体征.SBO若伴有脊髓神经损伤会影响脊髓的正常解剖,使其受到异常牵拉,局部缺血、缺氧,可造成神经功能障碍而产生一系列临床症状,称脊髓栓系综合征(tethered spinal cord syndrome,TCS).国内外目前对SBO特别是合并TCS时的诊治存在一定争议,故本文就SBO的病因、发病率、及诊断治疗研究进展进行综述.“,”As a subtle form of dysraphism with one or more split spinous processes and widened interpedicular distances on plain radiography,spina bifida occulta (SBO) is often combined with intact dorsal skin.Occurring at the level of lumbosacral portion,it affects multiple systems,such as nervous,urological,digestive and motor systems.If associated with traction,hypoxic-ischemia and other malformations of spinal nerve lead to spinal nerve injury and manifest a series of related symptoms referred to as tethered spinal cord syndrome (TCS).In light of many controversies in its diagnosis and therapy,this review summarizes the pathogenesis,prevalence,diagnosis and treatment of SBO to assist its clinical management.
