Purpose of this study is to compare the reduction of discogenic pain associated with disk herniation in two groups. Group A (31 patients) with lumbago, with/ without sciatica, with no neurologic deficit followed consernative treatment (antiflammatory drugs, physiotherapies) and the group B (31 patients) with the same symptoms submitted in percutaneous disc decompression after six weeks consernative treatment with poor results. Follow up had a period of six months, one year and two years in two groups. All patients in both groups evaluated clinically and the symptoms registrated in special protocol that included pain distribution, sensation, muscle strength and reflections (ahilleus and patellar). All of them submitted in X-ray and MRI so that the two groups have the presuppositions for percutaneous decompression of disc (absense of a free, non-contained or sequestered fragment, remained disc height > 50%, no neurologic deficit, no arthritis in facets). An AVS scale on a questionnaire adapted to Greek population helped assessing pain relief degree, life quality and mobility improvement. The method that we used is t-test for small independent patterns.

We found a statisticasignificant decrease on terms of pain relief, mobility and life improvement during the one and two years follow-up in group B which submitted in percutaneus decompression of intervertebral disks comparetively with A
