保肢手术已成为目前治疗骨与软组织恶性肿瘤的常规方法。随着患者生存期的延长,假体相关并发症日益凸显,而其中以无菌性松动(aseptic loosening,AL)较为多见。Henderson等[1]回顾分析了5个中心的数据后得到肿瘤型假体AL的发生率为4.7%,占所有假体失败原因的19%,排在失败原因的第2位;在其进行的文献回顾分析中,AL占肿瘤型假体失败原因的第1位,发生率为10%。肿瘤型假体AL的治疗无疑是具有挑战性的,因为既
Limb salvage surgery has become the conventional treatment of bone and soft tissue malignant tumors. Prosthesis-related complications have become increasingly prominent with the prolongation of patient survival, and aseptic loosening (AL) is more common. Henderson et al. [1] reviewed the data from 5 centers and found that the incidence of AL was 4.7%, accounting for 19% of all the causes of failure and the second in the cause of failure. Literature review and analysis, AL accounted for the failure of tumor-type prosthesis first place, the incidence was 10%. The treatment of tumor-type prostheses AL is undoubtedly challenging because both
