Event Description
|
Patient presented to hcp approximately 4 months post-operatively of her primary hip replacement after she felt something 'give' in her hip.She immediately detected a squeak in her hip indicating something had changed.She had no pain and walked normally.She has in a metal on polyethylene bearing, so squeak is not expected.The surgeon suspected the acetabular liner may have dislodged from the shell.This was from radiographic analysis.Patient was taken to theatre today (within 24hrs) and when opened, it was confirmed that the acetabular liner was dislodged from the pinnacle shell.The squeak was deemed to have been the metal head rubbing on the inside of the pinnacle shell where the dislodged liner should have been.A new replacement liner and femoral head were inserted, hip reduced and routine closure.The surgeon is confident all will be well.The concern was why the liner disengaged from the shell.There were also 2 missing lugs on the periphery of the liner.Revision operative notes (b)(6) 2021 indicate the patient received a right total hip revision.In addition to what has been previously reported, the patient also experienced a 4-8mm leg length discrepancy pre-revision and adhesions were encountered and removed once in the joint.The surgery was completed without complication indicated.
