laser disk decompression
The long term outcome, the complications and suboptimal results which may accompany open disk surgery have led to the early development of other treatment techniques that would avoid a surgical approach through the spinal canal and an extensive disk ablation. Percutaneous removal of nucleus pulposus has been performed with a variety of chemical and mechanical techniques for the past several years. These techniques consist of removing all or part of the nucleus pulposus to induce more rapid healing of the pathological lumbar disk. Percutaneous nucleotomy is now widely used, as it is much less invasive than surgical discectomy. To date, the most promising of these minimaly invasive therapies used for treatment of disk herniations is Percutaneous Laser Disc Decompression (PLDD).
