【摘要】：目的：通过研究1：1骨盆DR片制作方法,使之成为放射科的制片规范,探讨其在人工髋关节置换术前准备中的指导意义。方法：收集52例于2013年12月至2014年10月在广西医科大学第四附属医院行初次全髋关节置换术患者的临床资料。通过术前以一元人民币硬币作为参照物制作1：1大小骨盆平片,术前应用模板测量并预测假体型号,与术中所用实际假体大小进行比较,分析该制作方法的准确性。结果：术前规范制作的骨盆平片可用于术前计划,并可较好的预测假体型号：术前预测髋臼假体与实际所用假体完全符合的有34例(65.4%),相差一个型号有15例(28.8%),相差≥2个型号3例(5.8%),其符合优良率为94.2%；股骨假体与实际假体完全符合为30例(57.7%),相差1个型号18例(34.6%),相差≥2个型号号4例(7.7%),股骨假体的符合优良率为92.3%。结论：通过术前规范制作真实尺寸骨盆平片并进行模板测量可精确的预测术中假体型号,为全髋关节置换术提供参考依据,具有一定的临床指导意义。
[Abstract]:Objective: to study the method of making 1:1 pelvic DR film and to make it the standard of radiology department, and to explore its guiding significance in the preparation of artificial hip arthroplasty. Methods: the clinical data of 52 patients undergoing initial total hip arthroplasty from December 2013 to October 2014 in the fourth affiliated Hospital of Guangxi Medical University were collected. The 1:1 pelvis plain film was made with one yuan coin as reference before operation. The model of prosthesis was measured and predicted by using template before operation. The accuracy of the method was analyzed by comparing with the actual size of prosthesis used during operation. Results: the pelvis plain film made before operation can be used for preoperative planning. There were 34 cases (65.4%) with a difference of one type (28. 8%) and 3 cases (5. 8%). The excellent and good rate of predicting acetabular prosthesis before operation was 94. 2% (5. 8%). There were 30 cases (57.7%) with complete agreement between the femoral prosthesis and the actual prosthesis, 18 cases (34.6%) were different in one model, 4 cases (7.7%) were different from the actual prosthesis. The excellent and good rate of femoral prosthesis was 92.3%. Conclusion: making real size pelvic plain film and measuring template before operation can accurately predict the type of prosthesis during operation and provide reference for total hip arthroplasty. It has certain clinical significance.
