To evaluate the therapeutic effects of lumbar disk herniation treated by semiconductor laser. Methods One-hundred cases of lumbar disk herniation diagnosed by clinic and CT or MRI within three months underwent percutaneous laser disk decompression, including 65 cases of L4-5 and 35 cases of L5-S1 disk. Results In this group of patients, the successful rate of penetration was 100% and the rate of efficiency was 72%. There was no complication in the following 6-18 months. Conclusion Percutaneous laser disk decompression with semiconductor laser was a convenient, safe, efficient and minimally invasive technique.
In recent years, the author of semi-conductor laser therapeutic apparatus using percutaneous laser disc decompression (percutaneous laser disk decompression, PLDD) treatment of lumbar disc herniation, has achieved some results. Automatic aspiration of the technology and compared to excision, a simple, safe, injury, etc., are presented below.
100 cases of 100 patients with intervertebral disc, the success rate of puncture was 100%, follow-up period was 6 to 18 months. Reference MacNab  to evaluate the standard cure, 72% efficient. Of which 22 patients were cured and 50 cases of effective, 28 cases were followed up for 6 months without improvement in symptoms was considered null and void, without any complication. According to the affordability of different patients, respectively after 3,6 months or 1,3,6,12-month CT or MRI follow-up visit, some cases (24/100) 1 month for only the performance of the Department of nucleus density circular lower three months after the performance of some patients to varying degrees for the disc back to Steiner (49/100), part of cases (23/100) had no significant disc back satisfied, but to improve symptoms in varying degrees.
