Dislodgement of a cemented exeter femoral stem during closed manipulative reduction of a dislocated total hip replacement

INTRODUCTION: The incidence of cemented femoral stem migration and dislodgement even though has been described is extremely unusual. There is a high chance of polished femoral stem displacement happening while trying to reduce a dislocated total hip replacement by closed measures. PRESENTATION OF THE CASE: A 73 year old lady who had an Exeter cemented total hip replacement about two weeks back was admitted from Accident and Emergency with a dislocation. During the closed manipulative reduction under general anaesthesia it was noted that the femoral stem has dislodged from the canal. She underwent revision of the total hip replacement with good outcome. DISCUSSION: Femoral stem dislodgement occurs in total hip replacement if polished stem or inadequate cementing of the collar is carried out. CONCLUSION: Gentle manipulative reduction under general anaesthesia of dislocated total hip replacement should be carried out if the polished femoral stem is used.
