objective:to investigate the anatomical features of lumbosacral nerve roots in epidural space to provide the anatomical basis for selective posterior rhizotomy (spr).
目的:探究腰骶部脊神经根在硬膜外间隙的解剖情况,为临床spr手术提供解剖学依据。
objective:to provide sectional anatomical basis and ct image information of the lumbosacral nerve canal for the clinical diagnosis of lumbar spinal stenosis.
目的:为临床诊断腰椎管狭窄癥提供腰骶神经根管的断层解剖学及ct资料。
result:37 of 724 patients(rate 5.1%)were complicated with lumbosacral nerve root anomalies.
结果:724例腰椎间盘突出癥患者有37例神经根变异,发生率为5.1%。
aim:to report lumbosacral nerve root anomalies syndrome.
目的:报道临床所见腰骶神经根异常综合征。
results:the length of lumbosacral nerve roots in epidural space is short and extremely difficult to be exposed.
结果:腰骶部脊神经根在硬膜外间隙长度短,且显露困难。
objective:to study the technique and extensive indications for lumbosacral nerve root decompression using the microendoscopic discectomy (med) system.
目的:探索扩大脊柱后路显微内窥镜间盘切除(med)系统腰骶神经根减压术适应证的技术。
