| 3 | Successful hip revision surgery following refracture of a modern femoral stem using a cortical window osteotomy technique:A case report and review of literature显示文摘BACKGROUND The ExeterTM Universal cemented femoral component is widely used for total hip replacement surgery.Although there have been few reports of femoral component fracture,removal of a broken femoral stem can be a challenging procedure.CASE 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 refracture.We performed revision surgery and removed the distal cement using a cortical femoral window technique,followed by reimplantation with an uncemented,modular,distally-fixed uncemented stem.The patient experienced an uneventful postoperative recovery.CONCLUSION Re-fracture of a modern femoral ExeterTM stem is a rare event,but technical complications related to revision surgery can lead to this outcome.The 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. | Carlos M Lucero Juan B Luco Agustin Garcia-Mansilla Pablo A Slullitel Gerardo Zanotti Fernando Comba Martin A Buttaro | 2023 | World Journal of Methodology2023，13，5： | 0 |
