There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anteriorposterior plane and in Gruen zones 8,9 and 12 in the lateral plane.Typical areas of radiolucency were identified in Gruen zones 2～5 and 10～12 in the middledistal of the stem.Voids appeared in Gruen zones 3～5 and 10～12 in the distal of the stem.

结果(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度 mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2～5区和10～12区；气泡影出现在假体远端的3～5区和10～12区。

There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anterior-posterior plane and in Gruen zones 8,9 and 12 in the lateral plane. Typical areas of radiolucency were identified in Gruen zones 25 and 1012 in the middle-distal of the stem. Voids appeared in Gruen zones 35 and 1012 in the distal of the stem.
