Event or Problem Description
It was reported that approximately four months post-implantation, the patient underwent a hip revision due to instability, recurrent dislocations, and impingement from poor positioning of implants.The surgeon attributed the recurrent dislocation to poor cup placement.The trochanteric claw had anterior fixation resulting in tissue impingement.During the revision, a competitor cup was cemented into the existing cup; the head and liner were exchanged; and the stem and claw were retained with some tissue around the greater trochanter debrided.Attempts have been made and no further information has been provided.
