Despite excellent results, failure of osseointegration does occur in femoral revisions performed with extensively porous-coated stems. This study examined the outcome of rerevision of a failed extensively porous-coated femoral stem with yet another extensively porous-coated stem. Between 1980 and 2000, we performed 711 femoral revisions using an extensively porous-coated device. Fifteen patients (16 hips) were known to have undergone a rerevision of this femoral component using another porous-coated stem. At latest follow-up, 2 patients (3 hips) were deceased, leaving 13 patients. At a mean follow-up of 9.8 years, none of the cementless stems had required another revision (100% survivorship), and 12 (92%) of the 13 stems were bone ingrown based on radiographic examination.
尽管取得了优异的结果，但在使用广泛多孔涂层柄进行的股骨翻修手术中，骨整合失败的情况确实会发生。本研究检查了使用另一个广泛多孔涂层柄对失败的广泛多孔涂层股骨干进行再次翻修的结果。1980年至2000年期间，我们使用广泛多孔涂层装置进行了711例股骨翻修手术。已知有15名患者（16髋）使用另一个多孔涂层柄对该股骨部件进行了再次翻修。在最新随访时，2名患者（3髋）已去世，剩余13名患者。平均随访9.8年时，无骨水泥柄需要再次翻修（生存率100%），根据影像学检查，13个股骨柄中有12个（92%）出现骨长入。
