Malignant mesenchymal tumors are a diverse group of aggressive cancers originating from mesenchymal cells in connective tissues such as bone, muscle, cartilage, and fat. These tumors often invade surrounding tissues and metastasize to distant organs, posing significant treatment challenges. Among them, malignant mesenchymal tumors located in the distal femur are particularly rare, with limited reports detailing effective surgical and functional reconstruction strategies following wide resection. This case report focuses on the treatment of a distal femoral malignant mesenchymal tumor managed at our clinic, where wide resection was followed by reconstruction using a tumor resection prosthesis and extensor mechanism transfer. The report highlights the innovative surgical technique employed to restore extensor function while maintaining structural integrity, addressing a critical gap in the literature. By sharing insights into this approach, this report aims to contribute to the growing body of knowledge on limb salvage surgery and improve outcomes for patients with similar complex conditions.
恶性间充质肿瘤是一组源自骨、肌肉、软骨和脂肪等结缔组织中间充质细胞的侵袭性癌症。这些肿瘤常侵犯周围组织并转移至远处器官，带来重大的治疗挑战。其中，位于股骨远端的恶性间充质肿瘤尤为罕见，关于广泛切除术后有效的手术及功能重建策略的详细报道有限。本病例报告聚焦于我院诊治的一例股骨远端恶性间充质肿瘤，采用肿瘤切除假体及伸肌机制转移进行广泛切除术后重建。该报告突出了所采用的创新手术技术，即在维持结构完整性的同时恢复伸肌功能，填补了文献中的关键空白。通过分享对该方法的见解，本报告旨在为肢体挽救手术不断增长的知识体系做出贡献，并改善患有类似复杂病症患者的治疗效果。
