照相在髋关节置换术中的临床应用

RADIOGRAPH IN OPERATION OF HIP REPLACEMENT AND ITS CLINICAL SIGNIFICANCE

目的:评价术中照相在髋关节置换术中的意义。方法:自2002年5月-2009年4月,共完成髋关节置换术586例,其中髋置换614髋、翻修35髋,术前髋Harris评分26-66分。根据术中是否拍摄X光片分为两组:A组,术中照相,共完成294髋;B组,为无照相组,完成320髋。结果:A组病人双下肢长度差异明显小于B组(P<0.01);A组病人髋臼外展角度明显小于B组(P<0.01);A组颈干角均为130-135°,B组有22例颈干角为135-140°、15例为120-125°;A组有2例术中骨折,B组有13例术中骨折。结论:髋关节置换术中照相是正确判断假体位置,避免或减少假体周围骨折、双下肢不等长的一种有效方法。

Objective：To evaluate the significance of radiography in operation of hip replacement.Methods：586 cases hip replacement were completed from 2002.5 to 2009.5,among them,614 hips were replaced,35 hips were rebuilt.Before operation,the Harris score was 26-66.The patients were divided into 2 groups according to if the patients applied radiography during operation;The patients in group A applied radiography while the patients in group B did not.Results：Difference of length of 2 lower limbs of patients in group A was obviously lesser than that of patients in group B（P0.01）.The accetabulum abduction angle of patients in group A was significantly smaller than group B（P0.01）.The collodiaphyseal angle of patients in group A was 130-135°;in group B,collodiaphyseal angle of 22 patients was 135-140°,15 patients was 120-125°.In group A,2 cases occurred fracture during operation;while in group B was 13 cases.Conclusions：Intraoperative radiography in hip replacement is an effective method to exactly judge the position of prosthesis,avoid or reduce periprothetic fracture and discrepancy between 2 lower limbs.
