目的探讨单张X线片法在发育性髋关节脱位转子下旋转截骨矫形术中的应用价值。方法回顾性分析在新疆医科大学第一附属医院2012年1月-2013年6月行手术治疗的56例小儿发育性髋关节脱位患者的临床资料,其中前倾角>40°行转子下旋转截骨术者33例(46髋),术中用单张X线片法C型臂透视机下测量前倾角决定是否要行股骨转子下旋转截骨术,矫正后同样方法测量前倾角确定矫正度数是否满意。结果单张X线片法测量前倾角>40°的33例发育性髋关节脱位患者行转子下旋转截骨术后,前倾角矫正至12°~30°,平均21°,术中前倾角矫正效果满意。结论在转子下旋转截骨矫形术中用单张X线片法测量发育性髋关节脱位患儿的前倾角简便、可靠。
Objective To investigate the value of single-slice X-ray in the development of osteotomy and orthotics under developmental hip dislocation. Methods The clinical data of 56 patients with pediatric developmental dislocation of the hip who underwent surgery in the First Affiliated Hospital of Xinjiang Medical University from January 2012 to June 2013 were retrospectively analyzed. Among them, the anterior tilt angle> 40 ° 33 patients (46 hips) underwent surgery under the C-arm fluoroscopic X-ray film to determine whether the anterior tilt osteotomy under femoral trochanter, correction after the same method to determine the degree of correction of anteversion to determine whether the degree of correction satisfaction. Results In 33 patients with developmental hip dislocation with anteversion> 40 °, the anterior tilt angle was corrected to 12 ° ~ 30 ° with an average of 21 ° and the anterior inclinations were corrected Satisfactory results. Conclusions The anteversion of children with developmental dislocation of hip in single-slice X-ray film during rotator osteotomy is simple and reliable.
