目的 探讨椎间盘镜手术系统(MED_Ⅱ)治疗腰椎间盘突出症的临床应用及适应症。方法 采用MED_Ⅱ技术进行髓核摘除及神经根管减压术。结果 本组治疗腰椎间盘突出症75例,随访6～12个月,按NaKai标准评定:优59例,良12例,可3例,差1例。结论 MED_Ⅱ能充分显示硬脊膜,神经根及突出的髓核组织,手术安全,减压充分,创伤小,保持了脊柱后柱完整性与稳定性。适用于单节段腰椎间盘突出症或合并相同节段神经根管狭窄症。

Objective To evaluate the validity of clinical application of MEDⅡ system and indications in lumbar disc surgery . Methods Retrospective analysis was conducted for data of 75 cases with protruded lumbar discs which were treated by resection of the nucleus putposus and nerve root decompression with the MEDⅡ system. Results The follow-up (6-12 months) results demonstrated that, according to the Nakai standard, excellent was obtained in 59 cases, good in 12, ameliorative in 3 and poor in the remaining case. Conclusions The authors concluded that, the dura mater spinalis, the nerve roots and the protruded disc could be exposed fully under the MEDn system during surgery. The other advantages in using of this system for treatment of the protruded disc are as follows: It is relatively safe and reliable, decompression is full and it is less traumatic, so that it is helpful to maintain the integrity and stability of the spinal column. It is suitalbe for treatment of protrusion of single lumbar intervertebral disc or these cases concommitant with stenosis of nerve root canal.
