46例Denis B型胸腰椎爆裂骨折患者随机分为伤椎同种异体骨植入术（24例）和伤椎内硫酸钙植入术（22例）治疗。两组的手术时间、术中出血量、术后神经功能恢复情况、术后Cobb角矫正、预防相邻节段退变及术后疼痛视觉模拟评分系统评分、日本骨科协会评估治疗分数差异均无统计学意义（均P＞0.05）。提示异体骨植入组在术后伤椎高度的维持及降低伤椎骨缺损程度的效果，优于硫酸钙植入组（ P＜0.05）。

To compare the clinical efficacy of treating Denis type B thoracolumbar burst fracture with allogenic bone and calcium sulfate implanting in injured vertebra.A total of 46 patients were randomly assigned into 2 groups.Group A( n=22) received allogenic bone implanting in injured vertebra while group B( n=21) had calcium sulfate grafting in injured vertebra.Group A was better than group B in maintaining tanterior vertebral body height and lessening the degree of bone defect ( P <0.05 ).No significant differences existed in operaive duration , blood loss volume, correcting Cobb′s angle, preventing degeneration of adjacent segments , visual analogue scale ( VAS) and Japanese Orthopaedic Association ( JOA) scores and the degree of bone defect ( P>0.05).
