title: Ceramic insert dislodgment after revision ceramic-on-ceramic total hip arthroplasty.
abstract: We present a case of early ceramic insert dislodgment in a young patient with revision uncemented ceramic-on-ceramic total hip arthroplasty. The presentation may be subtle and the dislodgment may go unnoticed. This incidence draws our attention to the need for careful intraoperative confirmation of the insert position and frequent serial radiographic monitoring. The case also draws speculation of possible design flaws in the locking mechanism predisposing for the insert dislodgment.
