 We report a case in which a ABS cup (Kyocera,Kyoto,Japan) produced an abnormal sound and revision THA was performed before progression to dissociation or fracture. Cementless ABS HA shells sometimes dissociate because of over-crimp with a ceramic ball and a ceramic liner. Approximately 70% of the cases in which fractures have occurred have been accompanied by prodromal symptoms,and most symptomatic cases have resulted in implant fracture within 1 month after the prodromal symptoms developed. The surgical outcome of revision THA after fractures has not been good,and there is the drawback of a limited selection of bearing surfaces. Thus,implant revision should be considered when any prodromal symptoms,such as an abnormal sound,develop.
