摘要:

背景:医用硫酸钙人工骨用以填充脊柱结核病灶清除后的骨缺损存在争议,长期肌注链霉素抗结核具有患者依从性差等弊端,局部应用可克服这些不足之处。
目的:观察在胸腰椎结核后路病灶清除植骨融合内固定中,应用含链霉素的硫酸钙人工骨与自体骨混合植骨的疗效。
方法:收集2008年3月至2012年6月收治的18例胸腰椎结核患者,在正规抗结核的基础上采用一期后路病灶清除、含链霉素的硫酸钙人工骨与自体骨混合植骨及内固定治疗,观察患者局部切口情况,有无不良反应及临床症状恢复情况,定期影像学检查对植骨融合和后凸畸形矫正的情况进行分析。
结果与结论:所有患者内固定后伤口均一期愈合,临床症状明显缓解,后凸畸形获得不同程度的矫正,矫正角度无明显丢失,无全身不良反应。17例患者一次手术治愈,1例患者于内固定后9个月结核复发再次行前路手术后治愈;胸腰椎X射线检查,内固定后1周硫酸钙人工骨粒显影清楚,内固定后3个月显影不清,内固定后6-9个月植骨部位获骨性愈合。提示在胸腰椎结核手术治疗中应用含链霉素的硫酸钙人工骨不仅可以补充植骨量,而且可以提高局部抗结核药物的浓度,具有可靠的安全性和满意的临床疗效,是一种优良的骨移植替代材料。

Abstract:

BACKGROUND: Medical grade calcium sulfate bone for bone defects after removal of spinal tuberculosis is controversial; however, patients undergoing long-term intramuscular injection of streptomycin for anti-tuberculosis show a poor compliance, and local application can overcome these shortcomings.
OBJECTIVE: To study the clinical efficacy and outcome of medical grade calcium sulfate bone incorporated with streptomycin and autogenetic bone graft combined with posterior debridement and instrumentation for thoracolumbar spinal tuberculosis.
METHODS: From March 2008 to June 2012, 18 patients with thoracolumbar spinal tuberculosis were treated with one-stage posterior debridement, medical grade calcium sulfate bone incorporated with streptomycin and autogenetic bone graft and instrumentation on the basis of regular anti-tuberculosis. Incision healing, adverse reactions and the change of clinical symptoms were recorded. Bone fusion and deformity correction were analyzed by the regular X-ray examination.
RESULTS AND CONCLUSION: All the patients acquired satisfactory incision healing without obvious general adverse reactions. Clinical symptoms were differently relived. Kyphosis was corrected to some degree and the correction had no loss. Seventeen patients were cured after the first operation. Tuberculosis recurred in one patient 9 months after the first surgery and was cured after the second anterior surgery. X-ray examination showed that the calcium sulfate bone was clear 1 week after surgery and unclear 3 months after surgery. Bone fusion appeared 6 to 9 months after operation. These findings indicate that the application of medical grade calcium sulfate bone incorporated with streptomycin could achieve good effects in the treatment of thoracolumbar spinal tuberculosis, which is an excellent substitute material for bone graft. It not only could repair bone loss but also increase the concentration of anti-tuberculosis drugs.
