41 non-cement total hip arthroplasties with the Mecring cup are reported in this paper. The follow-up results in an average of 14 months showed that this operation relieved the hip pain and improved the functional capacity and the motion of the hip. 80.5% of the reported hips gained excellent or good results. Because the cup was firm on the acetabulum with the thread, the defect of bone was smaller and the cup revision was easier than others, it is applicable not only for the elderly but also for younger patients. The relationship between the hip function and cup position was observed and it suggested that the correct abduction angle of the cup should be 40-50 degrees and the anteversion angle 5-20 degrees. The postoperative complications were dislocation and ectopic ossification.
本文报道了41例采用Mecring髋臼杯的非骨水泥型全髋关节置换术。平均14个月的随访结果显示，该手术缓解了髋关节疼痛，改善了髋关节功能和活动度。报告的髋关节中有80.5%获得了优或良的效果。由于髋臼杯通过螺纹牢固地固定在髋臼上，骨缺损较小，髋臼杯翻修比其他类型更容易，因此它不仅适用于老年人，也适用于年轻患者。观察了髋关节功能与髋臼杯位置之间的关系，结果表明髋臼杯正确的外展角度应为40 - 50度，前倾角为5 - 20度。术后并发症为脱位和异位骨化。
