摘      要：BACKGROUND The ExeterTM Universal cemented femoral component is widely used for total hip replacement *** there have been few reports of femoral component fracture,removal of a broken femoral stem can be a challenging *** SUMMARY A 54-year-old man with a Dorr A femur sustained a refracture of a primary ExeterTM stem,two years after receiving a revision using a cement-within-cement technique(CWC)through an extended trochanteric osteotomy(ETO).The technical problems related to the CWC technique and the ETO played a major role in the stem fatigue *** performed revision surgery and removed the distal cement using a cortical femoral window technique,followed by reimplantation with an uncemented,modular,distally-fixed uncemented *** patient experienced an uneventful postoperative *** Re-fracture of a modern femoral ExeterTM stem is a rare event,but technical complications related to revision surgery can lead to this *** cortical window osteotomy technique can facilitate the removal of a broken stem and cement,allowing for prosthetic reimplantation under direct vision and avoiding ETO-related complications.
