Up to 8 years after replacement of hip-joints in 26 patients the strontium-85-uptake over both thighs was followed scintimetrically. In contrary to normal healing of fractures, this uptake became normal on the side of the operation not earlier than the end of the 2nd year after operation. One cause of this delay could be the continuing liberation of monomeres of polymethyl-methacrylates at the bed of the implant. It is important to consider the clinical signs on the opposite side, since there a raised strontium-85-uptake could produce a "pseudo"-diminished ratio between the two sides.
对26例髋关节置换术后长达8年的患者，通过闪烁扫描法跟踪双侧大腿的锶-85摄取情况。与骨折的正常愈合情况相反，手术侧的这种摄取情况直到术后第2年末才恢复正常。这种延迟的一个原因可能是植入物床处聚甲基丙烯酸甲酯单体的持续释放。考虑对侧的临床体征很重要，因为对侧锶-85摄取升高可能会导致两侧之间的比值出现“假性”降低。
