The Outcomes Of Percutaneous Laser Disc Decompression Combining With Percutaneous Lumbar Intervertebral Disc Ozone Injection In The Treatment Of Lumbar Disc Herniation And Analysis Of Influencing Factorsi

Objective:To observe the therapeutic effects of percutaneous laser disc decompression ( PLDD) combining with ozone ablation treatment technique and discussing the influencing factors to the treatment results of lumbar disc herniations。Method:We carried out retrospective and statistical analyses of 86 patients with lumbar disc herniation who were treated by PLDD combining with ozone ablation .According to modified Macnab criteria, an clinical effect analysis on influencing factor including age, gender,the course of disease,clinical symptoms, lumbar intervertebral space, combining bony or ligamentous spinal stenosis or not, angle of straight leg raising, degree of lumbar disk bulging at imaging were recorded.Results:According to modified Macnab criteria, the clinical evaluation results were excellent in 30 cases , good in 38 cases ,fair in 16 cases and poor in 2 cases . Clinical outcome is better in patients age less than 40 year-old , clinical course less than 2 years, back pain with radition to lower limb have better outcome than pure back pain, the angle of straight leg raising less than 60°have better outcome compared with more than 60°.Conclusion:Percutaneous laser disc decompression combining with ozone injection is an effective treatment for lumbar disc herniation. The effectiveness of treatment is related to age, the course of disease, clinical symptoms, and the angle of straight leg raising. Select the appropriate patients is expected to achieve a better result.
