摘　　要：目的探讨全髋关节置换术后常见并发症的X线表现，以提高对全髋关节置换术后并发症的诊断水平，评价x线诊断价值。方法分析76例全髋关节黄换术后出现并发症的病例。观察其X线表现，评价X线对并发症的诊断价值。结果股骨柄无菌松动49例，髋臼假体无菌松动14例，x线表现为假体周围轮廓与假体形态一致的透亮带伴或不伴假体移位；感染伴股骨柄假体松动3例，x线表现为假体周围轮廓与假体形态不一致的透亮带和（或）假体移位，同时伴有骨质破坏；股骨头脱位11例，x线10例表现为股骨头位于髋臼外．1例表现为股骨头在髋臼假体内不对称。结论x线平片检查是全髋关节置换术后并发症诊断和随访的重要方法。全髋置换术后并发症以假体松动最常见。Objective To explore the X-ray findings of the common complications after total hip arthroplasty（ THA ）, in order to improve the diagnosis of the complications of THA. Methods 76 cases with the complications after THA underwent X-ray examination. X-ray features and the value in the diagnosis of complications after THA were assessed. Results There were 49 cases with aseptic loosening of femoral component and 14 cases with aseptic loosening of acetabular component,radiographs showed the lucent zone alone the component, which had the same contour as the component. 3 cases had septic loosening of femoral component radiographs showed the lucent zone alone the component accompanied with bone destruction. The lucent zone had the different contour of the component . Both kinds of loosening might accompany with migration of the component or not. 11 cases had dislocation of femoral head,radiographs showed the head lying out of acetabulum in 10 cases, and asymmetrical position of the head in acetabulum in 1 case. Conclusion X-ray examination is an important inspection methods in diagnosis and follow-up of the complications of THA. The most common complications of post-operative THA is prosthesis loosening.
