| Objective: Nowadays,low back pain has become the most severe public health problem.The most common reason for outpatient and occupational disease is the low back pain.Low back pain may result in remarkable body incapacity,rigorous work efficiency decline and chronic pain aggravated.For the pathogenesis of low back pain various from mechanical and chemical factors,it takes more challenge for treatment.The degenerative of intervertebral disc tissue can lead to lumbar disc herniation and nerve root compression,which is regarded as the major reason for low back pain.Ninety percent of cases of low back pain are associated with lumber disc herniation occurring at the L4~L5 or L5~S1 level[1].Compare the clinical outcomes between percutaneous endoscopic lumber discectomy and Ozoneaugmented percutaneous discectomy.Methods: 65 eligible cases were divided into two groups,one group of 34 cases implement percutaneous endoscopic lumber discectomy and another group of 31 cases implement Ozone-augmented percutaneous discectomy.Measure the value of visual analog scale and JOA scale at the time pre-operation,two weeks after operation and six months after operation.Measure the value of Macnab at the time six months after operation.Evaluate clinical outcomes between two treatments by analysis the date of two groups.Results: 65 cases all complete operation successfully,without serious complication.There was significant improvement in VAS at two weeks and six months than pre-operation(P<0.05).The OPLD group showed statistically outcomes with regard to improvement in VAS value at two weeks than PELD group(4.77 ± 1.08 vs 5.48 ± 0.80).There was no significant difference in VAS at six months between the two groups.Conclusion: There was no difference between two treatments in short-term clinical outcome.Both PELD and OPLD showed favorable outcomes,the PELD has better outcomes than OPLD at two weeks after operation. |
