Abstract
Roentgen stereophotogrammetric analysis was used in the evaluation of subsidence in nine noncemented femoral components of the Biomet Taperloc prosthesis. After 2 years three components had subsided 0.7-0.9 mm. No distinct symptoms related to the micromotion appeared. The subsidence in this investigation was smaller than the reported subsidence of other noncemented prostheses.
摘要
采用X线立体摄影测量分析技术评估了Biomet Taperloc假体9个非骨水泥型股骨部件的下沉情况。2年后，3个部件下沉了0.7 - 0.9毫米。未出现与微动相关的明显症状。本研究中的下沉情况小于其他非骨水泥型假体所报道的下沉情况。
