Study of the puncture approches to epidurai lateral recess / 中华麻醉学杂志

ABSTRACT

The new approaches were designed to have anti-inflammatory analgetics act concentratively on the surrounding of pathological nerve roots or to inject collagenase directly to the protruding lumbar intervertebral disc for more simple and effective treatment of the low back pain. Method: The approaches to epidural lateral recess via incisura margo lateralis of lamina arcus vertebrae or margo medialis of joint processus artieularis were supposed and applied in clinic after study of anatomy and analysis of lumbar vertebra X-ray and CT photographes. The safety and feasibility of the approaches were evaluated according to the test of block region, measurement of therapeutic effect and monitoring of CT during the whole procedures in some cases. Result: A total of 170 cases via the incisura margo lateralis of lamina areus vertebrae were tested, 168 cases turned out to be successful and 2 cases failing. Another 15 cases via margo medialis of joint proeessus articularis, all punctures were successful. Conclusion: The approaches can lead to epidural lateral recess precisely to obtain a better treatment. When the technique is applied to discolysis, no X-ray machine will be needed and therefore no injury of X-ray occurs to both doctors and patients.
