      【摘要】 目的 探讨Denis B型胸腰椎爆裂骨折的有效治疗方法。方法 选取2010年2月至2013年1月我
院收治的74例Denis B型胸腰椎爆裂骨折患者，采用随机数表法分为观察组39例和对照组35例，分别植入同种
异体骨和硫酸钙。比较两组患者的手术情况、Cobb角、椎体前缘高度压缩率及骨缺损情况，评价术后视觉模拟评
分法(VAS)、日本骨协评估治疗分数(JOA)评分及Frankel脊髓损伤分级、Qswestry腰痛功能障碍分级。结果 观
察组患者的手术时间和术中出血量分别为(145.7±29.4) min和(287.6±100.3) ml，对照组分别为(147.3±30.6) min和
(280.5±96.7) ml，两组比较差异均无统计学意义(P>0.05)；两组患者术后的Cobb角改善情况比较差异无统计学意
义(P>0.05)，观察组的椎体前缘高度压缩率及骨缺损情况优于对照组，差异具有统计学意义(P<0.05)。观察组术
后VAS为(2.3±0.8)分，JOA为(25.8±1.4)分；Frankel C级0例，D级6例，E级33例；Qswestry P0级31例，P1级8例。
对照组术后VAS为(2.4±1.1)分，JOA为(26.3±0.9)分；Frankel C级0例，D级5例，E级30例；Qswestry P0级28例，
P1级7例。以上各项指标比较差异均无统计学意义(P>0.05)。结论 同种异体骨与硫酸钙内植入均能有效治疗
Denis B型胸腰椎爆裂骨折，且同种异体骨在改善椎体前缘高度压缩率及骨缺损程度方面更具优势。

【Abstract】 Objective To explore effective treatment options for patients with Denis B type thoracolumbar
burst fracture. Methods Seventy-four patients of Denis type B thoracolumbar burst fracture in our hospital from Febru-
ary 2010 to January 2013 were selected. The patients were divided into observation group (n=39) and control group
(n=35) according to a random number table, which were implanted with allograft and calcium sulfate, respectively. Two
groups were compared in surgical cases, Cobb angle, vertebral height compression ratio and bone defects. The postopera-
tive Visual Analogue Scale (VAS), Japan Association for Assessing Bone Treatment Fraction (JOA) score and Frankel
classification of spinal cord injury, Qswestry back pain dysfunction classification were evaluated. Results The opera-
