【摘要】 目的 探讨新鲜与防腐标本椎体骨密度的差异为骨科实验研究提供科学依据。方法 选用同一地区、同一种族、同一性别、同一年龄段(35岁±2岁)新鲜标本，摄X线除外骨折、肿瘤、结核、风湿病及先天畸形，取出T9～L4标本，逐一测量骨密度(BMD)后，选择骨密度相近的胸腰椎体(α＝0.20，P>0.20)80个，将胸腰椎随机分成5个配伍组，每组16个椎体，第1组当即测量骨密度。第2、3、4、5组浸于5%福尔马林溶液中，分别于3、6、12及24个月测骨密度。采用Stata 7.0统计软件进行方差分析和多重比较。结果 椎骨骨密度经福尔马林浸泡3个月后明显降低(P<0.05)。结论 短时间(不超过3个月)福尔马林浸泡椎骨的骨密度无明显影响，福尔马林浸泡超过3个月将明显影响椎骨的BMD。【关键词】 福尔马林；椎体；骨密度

【Abstract】 Objective To investigate the BMD difference between the fresh and embalmed vertebral body. The research will provide scientific basis for the orthopedic study.Methods 80 fresh vertebrae specimens were harvested for this study.All of them were at the same region,race and sex. Their ages ranged from 3～37 years(average 35±2 years).All of the specimens were Xrayed to exclude fracture,tuberculosis ,rheumatism,tumor and hereditary malformation.BMD was measured and the result was statistically anlyzed(α＝0.20 ......
