[Diagnosis and treatment of postoperative intervertebral infectio].

OBJECTIVE: To retrospectively explore the diagnosis and treatment of postoperative lumbar intervertebral disc infection. METHODS: Twelve patients who suffered from postoperative lumbar intervertebral disc infection between April 1995 and September 2004 were confirmed doubtlessly by the diagnosis. They were treated with early immobilization combined with early and sufficient antibiotics and adequate corticosteroid. Patients with severe symptoms were managed by percutaneous puncture and washing discectomy such as rising temperature and perivertebral muscle spasm besides nostalgia, and early debridement of all necrotic tissue was done. RESULTS: Six were healed by non-operation and operation in the other 6. All had gotten locomotion with corset after the operation for 6-8 weeks and were followed-up from 6 months to 3 years. They have achieved excellent outcomes. CONCLUSION: When a postoperative disc space infection occurs, early diagnosis and treatment should be undertaken to achieve excellent outcomes.

[Different operation methods for thoracolumbar spinal tuberculosis].

OBJECTIVE: To compare the advantages and disadvantages among the conventional operative methods with the primary anterior debridement, intercentrum auto grafting, and anterior internal fixation method for the thoracolumbar spinal tuberculosis, and to discuss the applying principle. METHODS: Twenty-seven patients with thoracolumbar spinal tuberculosis were treated by the primary anterior debridement, intercentrum auto grafting, and anterior internal fixation, 8 patients were treated by focus debridement and intercentrum auto grafting operations, and the other 22 patients were treated by focus debridement from Feburary 1998 to July 2003, and we analysed the status of the grafting bone fused, the neural function resumed, the malformation rectified and the whole cure ratio. RESULTS: All patients were cured after the follow-up of 15.2 months averagely. Three thoracic spinal and 1 lumbar spinal tuberculosis patients who suffered local infection were cured by debridement and other managements. The time of beginning active movement postoperatively was shortened, and the degrees of kyphosis correction had increased in the anterior internal fixation group compared with the other two groups (P <0.05). But the cost and the bleeding resulted from operation had increased in the anterior internal fixation group compared with the other two groups (P <0.05). CONCLUSION: The conventional and the modern operation methods of thoracolumbar spinal tuberculosis have respective advantages and disadvantages, so that they can complement rather than replace each other.

[Surgical treatment for lumbar discogenic low back pain].

OBJECTIVE: To explore the curative effect of surgical treatment for lumbar discogenic low back pain. METHODS: Forty-two patients with lumbar discogenic low back pain were treated with disc excision and lumbar interbody fusion: 12 of them were treated with posterior lumbar interbody fusion (PLIF), 30 with afront lumbar interbody fusion (ALIF). The clinical results were evaluated by pre- and post-operative visual analogue scale (VAS), and the fusion rates of the lumbosacral spine were evaluated by X-ray. RESULTS: The average follow-up period was 18 months, ranging from 6 to 36 months. Low back pain basically disappeared in 11 patients treated with PLIF, with mild back pain in one patient; VAS after the operation decreased significantly in comparison with that preoperatively (P<0.01). Low back pain basically disappeared in 28 patients treated with ALIF; VAS after the operation decreased significantly in comparison with that preoperatively (P<0.01). The fusion rate was 90% in patients treated with PLIF, and 93% in patients with ALIF. CONCLUSION: Disc excision and interbody fusion is effective in the treatment of lumbar discogenic low back pain, but the operation indications should be paid attention to.
