Outcomes of Large Joint Replacement in Patients with Bone Tumors and Causes of Complications
The results of large joint replacement in bone tumors were studied in 117 patients. Patients underwent implantation with the use of domestic individual oncological implants and foreign models of modular prostheses. In 42 (35.9 %) patients at different periods after the primary cancer arthroplasty, there were observed complications, 28 of them underwent re-replacement. The most common complications after replacement were: infectious - 18 (15.4 %) cases, aseptic loosening of the prosthesis stem - 18 (15.4 %). Tumor recurrences were detected in 10 (8.5 %) patients. Causes of complications after replacement were: previous surgery, previous radiotherapy, tumor localization, size of the removed tumor, the length of the resected bone fragments relative to the whole length of the bone, the duration of surgery, blood loss during surgery, construction of endoprosthesis and technique of its installation.
