[Infection of intervertebral space and the interventional therapy].

Objective: To investigate the effect of interventional therapy in the treatment of intervertebral space infection.

Methods: The needle was punctured into the infected intervertebral space from the post-lateral side of the spine monitored by X-rays. The pus was drained, the degenerative disc tissues and necrosis tissues were excised and taken out, and at the end a drainaging catheter was put into the space through the needle. The patient should lie in bed absolutely. The antibiotics was injected into the space through the silicon catheter every day. Three to four weeks later, the catheter was removed.

Results: All the 8 patients got good results after the therapy. The low back pain was dramatically alleviated instantly at the day of operation. Erythrocyte sedimental rate gradually descended. After 3 approximately 4 weeks of treatment,the catheter was removed.

Conclusion: Interventional therapy of the intervertebral space infection has notable advantage over the open operation.
