部分切除椎间盘能够缓解疼痛

 
 
根据一项最新研究，一种微创治疗腰椎椎间盘突出的新方法，预后良好，特别是对患坐骨神经痛的患者。

这种治疗方法叫做经皮椎间盘切除术，使用X线引导，通过皮肤和肌肉组织将套管插入椎间盘突出区域病变椎间盘，去除导致疼痛的膨大椎核。患者在注射区域使用足量的止痛和麻醉药物确保肌肉松弛，但是仍然保持清醒从而可以报告任何可能出现的疼痛。在进入椎核之后，去除穿刺探针，然后使用套管插入必须的设备，使过量的凝胶状物质蒸发或者吸出。在2周之内，大多数患者称恢复了50-60%，而3个月的时候称恢复了80-90%。
 
Partial Excision of Lumbar Disk Eases Pain 
 

A minimally invasive approach to treating herniated discs of the lumbar spine results in good outcomes, especially for patients with sciatica, according to a new study.

The procedure, called percutaneous diskectomy, is performed by inserting a cannula into the herniation through skin and muscle tissues, using x-ray guidance to direct it into the offending disk, to eliminate the portion of the bulging nucleus that is causing pain. Patients receive local pain relief at the injection site and enough anesthesia to relax, but remain awake so they can report any pain they experience. After accessing the disk, the puncturing stylet is removed, and the cannula is used to insert devices needed to vaporize or suction out excess gelatinous substance. Within two weeks, most patients say they are 50-60% better and by three months, they are 80-90% better.
