To introduce the METRx microendoscopes diskectomy system in the treatment of far lateral lumbar disc herniation.
Fourteen cases of far lateral lumbar disc herniation were operated with METRx from February 1999 to December 2002. Among them, the average age was 49 years old (range 41 - 55 years old), male in 10 cases, female in 4 cases. All cases were single disc herniation; L(4), 5 herniation in 6 discs, L(5)-S(1) herniation in 8 discs; foraminal disc herniation in 6 cases, extra-foraminal disc herniation in 8 cases.
All the cases were followed up from 12 to 46 months (average 26.5 months) with the results of excellence in 10 cases, good in 3 cases, fair in 1 case and no failure case. There were no disc infection, dura laceration, nerve root injury and herniation recurrence.
METRx is suitable for far lateral lumbar disc herniation with the advantages of minimal invasive, complete decompression of nerve root and rapid recovery. The correct approach and precise surgical technique are the key points for this operation.
介绍METRx微型内窥镜椎间盘切除术系统在治疗极外侧腰椎间盘突出症中的应用。
1999年2月至2002年12月，应用METRx对14例极外侧腰椎间盘突出症患者进行手术。其中，平均年龄49岁（范围41 - 55岁），男10例，女4例。所有病例均为单节段椎间盘突出；L4、5椎间盘突出6例，L5 - S1椎间盘突出8例；椎间孔内椎间盘突出6例，椎间孔外椎间盘突出8例。
所有病例随访12至46个月（平均26.5个月），结果优10例，良3例，可1例，无失败病例。无椎间盘感染、硬脊膜撕裂、神经根损伤及椎间盘突出复发。
METRx适用于极外侧腰椎间盘突出症，具有微创、神经根减压彻底、恢复快等优点。正确的入路和精确的手术技巧是该手术的关键要点。
