摘　　要：目的:探讨髋关节置换术后早期异常X线表现、成因及与临床的关系。方法:回顾性分析102例髋关节置换术后患者的术后CR图像及病例资料。结果:102例中共15例髋部有异常X线表现:假体髋臼结构异常并发脱位2例、并发劈裂骨折2例、大转子位置偏高4例、碎骨片及异位骨化钙化、残留7例、假体钢丝断裂错位1例。髋关节置换术后早期异常X线表现可分术后并发症及关节结构异常两大类。结论:髋关节置换术后早期异常X线表现不同,其成因及与临床的关系也不同,但互有联系,必须正确认识。Objective： To study the early abnormal X-ray features after hip joint replacement, the causes and their clinical relationship. Methods：Retrospectively analyzed the post-surgical CR features and their clinical materials of 102 patients after hip joint replacement. Results： Of the 102 patients, 15 patients had abnormal X-ray features： prosthesis-acetabulum str.uctural abnormalities associated with hip joint dislocation （n= 2） , associated with fissured fracture （n=2）, upward displacement of greater trochanter （n= 4）, residue bone fragment and ectopic ossification or calcification （n= 7）, mal-position of prosthesis due to broken steel wire （n= 1）. The causes of early abnormal X-ray features after hip joint replacement could be divided into two groups, including post-surgical complication and abnormalities due to arthrosis. Conclusion：There were various early abnormal X-ray features after hip joint replacement, which had different clinical causes, however, to recognize these issues is essential.
