远端综合征的临床表现与治疗

Clinical manifestations and treatment of far-out syndrome

远端综合征(Far-out syndrome, FOS)是一种以椎间孔外L5神经根受压引起的不同临床症状为特征的疾病。它区别于神经根在常见位置受到压迫,具有独特的解剖学特征。为了明确FOS的诊断,CT、MRI等是较好的诊断方法。对于确诊FOS的患者也应考虑保守治疗,但如果出现了无法缓解的症状,手术是解决问题的最好方法。减压肯定是有效的,但是否进行融合手术应该根据具体情况考虑。此疾病很少被报道,对于最佳治疗方法至今没有共识,也缺乏大样本的疗效分析和对照研究。未来应进一步开展相关研究,更好地诊断与治疗该疾病。

Far-out syndrome(FOS)is a disorder characterized by pain caused by compression of the L5 nerve root outside the foramina,which is different from the nerve root in the common position of compression,for its unique anatomical characteristics.In order to clarify thediagnosis of FOS,CT and MRI are better diagnostic methods.For patients who are irresponsive to standard conservative treatment,surgicalmanagement,with complete decompression and with or without fusion,is indicated.This disease is rarely reported,there is no consensus onthe best treatment,and there is a lack of efficacy analysis and controlled studies with large samples.Further research should be carried out tobetter diagnose and treat the disease.
