Abstract
目的 探讨快速成形(RP)技术在复杂骨盆骨折诊断治疗中的应用价值.方法 2003年10月~2004年5月收治6例严重骨盆骨折患者,经电子束CT(EBT)检查,将所得数据经过转化输入RP机,制作出骨盆骨折模型;根据模型诊断骨折类型,指导临床手术治疗.将本组5例手术患者的出血量、输血量及手术时间与常规手术的11例类似患者进行对比.结果 本组6例患者均成功制备出1∶1等大的RP模型,通过在模型上进行术前手术方案的制定,使手术操作更加简便和微创化.本组5例手术患者的平均出血量、输血量及手术时间分别为800 mL、600 mL及3.2 h,11例常规手术患者分别为1300 mL、1000 mL及4.5 h.结论 采用RP技术可获得与患者骨盆骨折真实情况完全相同的骨盆模型,有利于直观、准确地了解骨折伤情.可根据骨折模型选择手术方案及内固定方式,并可对内固定钢板进行预先塑形,有利于减少手术创伤、缩短手术时间、提高手术质量。
