[An early follow-up of the mecring cup in total hip arthroplasty].
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.
