Abstract
We have performed percutaneous LASER disc discectomy for 34 patients with 56 lumbar herniated discs. Its indication is 1) resistant with conservative treatment, 2) leg sign is evident 3) protruded disc on MRI imaging is recognized. Operative procedures are as follows: first, stick the pilot needle into the disc under imaging with prone position. The diameter of the needle is enlarged with canula. Finally, a 2.5mm cannula is inserted and from that portal, Nd-YAG LASER was radiated through light fiver cable. Its' energy is 40W and is raditated until no resistance on the probe is felt. Preoperative and postoperative JOA lumbar score was used for evaluasion. Is all cases, postoperative JOA score was superior than that in preoperative period. Patients were satisfied to know successful results with minimal invasive operation in local anesthesia. Therefore, we conclude that PLDD is the safe, low invasive and effective treatment for lumbar protruded disc herniation, and its effect is more evident younger patients.
