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.
引言
尽管已有人描述过骨水泥型股骨柄移位和脱位的发生率，但极为罕见。在试图通过闭合措施复位脱位的全髋关节置换时，抛光的股骨柄有很高的移位几率。
病例介绍
一名73岁女性，约两周前接受了埃克塞特骨水泥型全髋关节置换，因脱位从急诊入院。在全身麻醉下进行闭合手法复位时，发现股骨柄已从髓腔中脱出。她接受了全髋关节置换翻修术，效果良好。
讨论
如果使用抛光柄或柄颈骨水泥固定不充分，全髋关节置换中会发生股骨柄脱位。
结论
如果使用抛光的股骨柄，应对脱位的全髋关节置换在全身麻醉下进行轻柔的手法复位。
