【摘要】 目的探讨 CT 检查对桡骨远端粉碎骨折诊断和治疗中的作用。方法选择我院2003年1月至2005年1月111例(118侧)接受手术治疗的桡骨远端骨折患者。对比桡骨远端 X 线片和 CT 扫描结果。结果在关节面压缩塌陷、关节面分离、关节面严重粉碎、桡腕关节半脱位这几项 X 片测量结果与 CT 测量结果有较大差异。关节面分离 X 线片检查显示42侧,CT 检查显示关节面分离70侧。X 线片检查显示关节面压缩塌陷31侧,CT 检查显示55侧。X 线片显示关节面骨块在3块或3块以上87侧,CT 显示101侧。骨折涉及下尺桡关节或伴有下尺桡半脱位,X 线片显示33侧,CT 显示56侧。桡骨短缩(>5 mm)X 线片显示108侧,CT 显示112侧。掌倾角改变X线片显示110侧,CT 显示113侧。尺偏角改变 X 线片显示64侧,CT显示69侧。结论对桡骨远端粉碎骨折损伤的严重程度、稳定性,是否需要手术,手术采取什么方式,手术入路的选择,术中特别需要注意的部位等情况,CT 可以为临床医生提供更直观、更详细的资料。同时也要求临床医生掌握 CT 检查的适应证及如何选择扫描的平面。更多还原

【Abstract】 Objectives To investigate and discuss the role of CT in the diagnosis and treatment of comminutive distal radius fractures.Methods One hundred and eleven consecutive patients(118 cases of fractures)who were admitted to Jishuitan hospital from January 2003 to January 2005 were included in this study.These patients all need operative treatment and accepted CT scans for better understandings of these injuries and helping to make operation plans.Results after comparing the results of X planes and CT scans,considerable differences existing between the two examinations were found in the measurements of articular compression and step-off,gapping,comminntion degree and subdislocation.This difference was manifested not only in the alteration of quantity but also in the change of quality.Conclusions Computed tomography can provide more vivid and detailed information of fractures for practitioners.Undoubtedly,CT is especially valuable in the evaluation of severity degree and stability of comminutive distal radius fractures, thus it helps us to determine whether operation is obligatory and choose the best method and approach of operation.Moreover,CT can also clearly show the important parts of fractures which need special attention in the process of operation.At the same time,practitioners are required to understand the indications of CT examination completely and know how to choose scan planes properly.更多还原
