Far lateral and related lumbar disc herniations that feature cephalad migration of fragments away from their disc space of origin can no longer be considered rare. Contemporary imaging techniques now reveal these herniations commonly. The anatomy of the foraminal and extraforaminal (far lateral) regions has been described and should be familiar to all spine surgeons. Each surgeon should be capable of recognizing the distinct entity of the far lateral disc herniation and should be adept at surgery in this region by one of several available techniques. I prefer a posterior, direct microsurgical approach through a midline incision featuring foraminotomy because of its ease, exposure, adaptability, and efficacy.
伴有碎片向头侧移位、远离其起源椎间盘间隙的极外侧及相关腰椎间盘突出症，已不再被认为罕见。现代成像技术如今常可发现这些突出症。椎间孔和椎间孔外（极外侧）区域的解剖结构已被描述，所有脊柱外科医生都应熟悉。每位外科医生都应能够识别极外侧椎间盘突出症这一独特病症，并应熟练掌握通过几种可用技术之一在该区域进行手术。由于其简便性、显露性、适应性和有效性，我更倾向于采用经中线切口并进行椎间孔切开术的后方直接显微手术入路。
