股骨远端骨水泥模块化假体是骨肿瘤和肢体抢救手术的可行选择。植入物失败的主要原因是植入物的质量差,机械应力,生化反应,和延长植入物在体内使用的时间。据报道,在患有骨肉瘤的受试者中,股骨远端假体植入物发生故障的发生率很少。与植入物失败相关的常见不良事件包括手术部位感染,肿胀,疼痛,外科手术的修订,囊肿形成,在软组织上堆积金属碎片.我们的病例报告总结了一名24岁的术后骨肉瘤患者经历的股骨远端骨水泥模块化假体的严重故障,该患者出现了剧烈的突然疼痛,并且无法承受右腿的重量,这些症状的突然发作在床上时发展。
A distal femoral cemented modular prosthesis is a viable option for post-bone tumor and limb salvage procedures. The major reasons for implant failures are the poor quality of implants, mechanical stress, biochemical reactions, and extended period of the implant in vivo use. Rare incidences have been reported of distal femur prosthesis implant malfunctioning in a subject having osteosarcoma. Common adverse events associated with implant failure include surgical site infections, swelling, pain, revision of the surgical procedure, cyst formation, and build-up of metal debris on soft tissues. Our
case report summarizes gross malfunctioning of a distal femur cemented modular prosthesis experienced by a 24-year-old post-operated osteosarcoma patient who developed excruciating sudden pain and the inability to bear weight on the right leg, with the sudden onset of these symptoms developing while turning in bed.
