True far lateral (extraforaminal) lumbar disc herniations are not rare. Diagnosis can be strongly suspected when high or mid-lumbar radiculopathies present clinically; diagnosis can be confirmed by computerized tomography and/or magnetic resonance imaging. When operative treatment is required, the off-midline paramedian exposure with little or no bone removal is the indicated procedure, produces little morbidity, and causes practically no low back disability.
真正的极外侧（椎间孔外）腰椎间盘突出并不罕见。当临床上出现高位或中位腰椎神经根病时，可强烈怀疑诊断；计算机断层扫描和/或磁共振成像可确诊。当需要手术治疗时，采用几乎不切除或不切除骨质的旁正中偏外侧入路是合适的手术方法，发病率低，几乎不会导致下腰部功能障碍。
