骨水泥椎体成形术在胸椎结核治疗中的应用

Application of bone cement vertebroplasty on thoracic tuberculosis

目的探讨骨水泥椎体成形术在胸椎结核治疗中的安全性及疗效。方法采用骨水泥椎体成形术治疗胸椎结核32例（A组），一期后路病灶清除、单纯植骨融合术治疗胸椎结核45例（B组）。结果两组术后随访8个月-3a。A组优30例、良2例，优良率100％；Cobb角术后得到部分至完全矫正，平均矫正12。，最后1次随访Cobb角矫正无明显丢失。B组优26例、良10例、差9例，优良率80％；植骨均骨性融合，融合时间6。8个月：Cobb角术后矫正6．6°，最后1次随访Cobb角矫正平均丢失3．8°。两组优良率及术后矫正Cobb角相比，P均〈0．05。结论骨水泥椎体成形术治疗胸椎结核安全、有效。

Objective To investigate the safety and effectiveness of bone cement vertebroplasty with thoracic tuberculosis. Methods 32 patients with thoracic tuberculosis in group A were treated by bone cement vertebroplasty. 45 patients with thoracic tuberculosis in group B were treated by one-stage posterior approach focus clearance and bone grafting. Results Followed up for 8 months to 3 years. 30 cases in group A were considered outstanding and 2 cases were considered excellent,the excellent rate was 100%. The Cobb angle was rectified partially or completely,the average recified Cobb angle was 12°. The rccified Cobb angle was not lose obviously in the last follow-up. 26 cases in group B were considered outstanding, 10 cases were considered excellent and 9 cases were considered bad, the excellent rate was 80%. All of the bone grafting were bony fusion which spending 6 to 8 months. The recified Cobb angle was 6.6°,the recified Cobb angle lost 3.8° average in the last follow-up. The excellent rate and recified Cobb angle after operation in group A were better than those in group B （ P 〈 0.05 ）. Conclusion Bone cement vertebroplasty is safe and effective on thoracic tuberculosis.
