Treatment of protrusion of Lumbar Intervertebral Disc (LID) with percutaneous laser disc decompression - a follow-up study of 108 patients

Abstract

To study the long-term clinical efficacy of protrusion of lumbar intervertebral disc with percutaneous laser disc decompression (PLDD). A statistics was conducted on 108 patients who had been treated with percutaneous laser disc decompression, the intervertebral height of related lesion spaces of patients in different time points after treatment and the intervertebral height ratio was calculated respectively; moreover, a statistics was conducted on VAS evaluation of patients in different time points, and the long-term efficacy after treatment with percutaneous laser disc decompression was evaluated with statistical method. The patients with follow-up period after operation respectively up to 5, 8 and 10 years and those in 3 years after operation were analyzed statistically in intervertebral height ratio and VAS scoring, and the difference was without significant statistical significance. Single-factor was analyzed to the factors likely to influence the effect of operation to get the authenticity of influence of age, disease duration and disease stage on the postoperative efficacy. Percutaneous laser disc decompression was featured by safety, efficacy and fewer complications in treatment of protrusion of lumbar intervertebral disc, and also it had no obvious influence on the spinal stability, and long-term postoperative efficacy was stable.
