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.
Highlights
Protrusion of lumbar intervertebral disc is a common clinical disease and frequently-occurring disease in Orthopedics Department
Through follow-up visit to the patients with protrusion of lumbar intervertebral disc treated with percutaneous laser disc decompression (PLDD), their intervertebral height was measured at different time points, and the result showed that, with the increase of time, the intervertebral height showed a trend of decline, and this kind of tendency was considered to be related with the degeneration of human body itself
It’s discovered that the comparison of intervertebral height in postoperative 10 years and the intervertebral height in postoperative 5 years and 8 years was of no significant statistical significance (P > 0.05), indicating that the intervertebral height after treatment was relatively stable in long-term change, which provided a basis for maintenance of long-term clinical efficacy
Summary
A slender light-guide fiber will be used during the treatment process for generating pulse laser, which vaporizes some nucleus pulposus of the prominent intervertebral disc, relieves or eliminates the oppress and stimulation of neural so as to realize the treatment purpose of improving the symptoms. This technology was applied by Choy and Ascher (Tassi et al, 2010) in clinical treatment of protrusion of lumbar intervertebral disc successfully for the first time in 1986, and with the advantages like high safety and simple operation, it became one of main means used for treatment of protrusion of lumbar intervertebral disc quickly. Retrospective analysis were conducted on 108 cases of patients with protrusion of lumbar intervertebral disc treated with PLDD and getting effective follow-up visits in the period from April 2003 to December 2013, the long-term efficacy of PLDD in treatment of protrusion of lumbar intervertebral disc was evaluated: Received 07 July, 2021 Accepted 09 Aug., 2021 1 Gansu Provincial Hospital of Traditional Chinese Medicine, Lanzhou, Gansu, China 2 Lanzhou Chengguan District Maternal and Child Health Center, Lanzhou, Gansu, China 3 Gansu Provincial Academy of Traditional Chinese Medicine, Lanzhou, Gansu, China
