摘要
目的设计一种新的测量髋关节旋转中心的方法,并将其与传统测量方法进行比较。方法选取中南大学湘雅二医院2017年1月至2019年4月收治的120例全髋关节置换手术(THA)患者的健康髋关节(120个髋)和20例健康志愿者的双侧髋关节(40个髋)的数据。对每位研究对象的髋关节以不同的角度(0°,7. 5°,15°和22. 5°)进行外展,并进行一系列X线检查和MRI检查。通过比较X线片和MRI图像获得股骨头旋转中心的运动轨迹,并对术前分别接受两种不同测量方法的67例手术患者的术前、术中和术后的各项资料进行对比。结果与传统测量方法相比较,本课题组新方法测量精度有提高;髋关节MRI扫描的结果验证了笔者新方法的客观性和精确性;术前测量和术后追踪的结果显示笔者的新方法比传统测量法有更好的临床效果。新方法测量的患者在术后没有发现假体脱位现象,术后回访追踪中的Harris评分高于目前常用的股骨头圆心法,VAS疼痛评分则前者低于后者。结论课题组创新的以髋关节不同外展角度的骨盆正位X线片为基础的新测量方法,显示比传统的测量方法所获得的数据更为精准,并显示出更好的临床效果。
Objective To design and evaluate a new method for measuring the center of rotation of the hip joint,and to compare it with the traditional methods. Methods Data of healthy hips of 120 total hip arthroplasty( THA) patients( 120 hips) and bilateral hips of 20 healthy volumteers( 40 hips) were collected. A series of X-rays and magnetic resonance imaging( MRI) were taken from each patient with the hip joint abductted at differenct angles( 0°,7. 5°,15°,and 22. 5°) . The motion track of rotation center was obtained by comparing these X-ray and MRI images. The preoperative and postoperative data of 67 surgical patients who underwent two different measurement methods before surgery were compared. Results Compared with traditional measurement methods,the accuracy of our new method was significantly improved;the results of hip MRI verified the objectivity and accuracy of our new method;preoperative measurements and postoperative follow-up results showed that our new method had a better clinical effect than traditional measurements. Conclusions The team’ s innovative new measurement method based on pelvic orthotopic X-ray photographs with different abduction angles of the hip shows more accurate data than traditional measurement methods and shows better clinical results.
