Prevention of dislocations after endoprosthetics implatation in patients with bone tumors

Currently, replacement of major joints and bones with endoprosthesis in patients with bone tumors is the golden standard in the treatment of this category of patients. The most frequent complications are instability of prosthesis (fractures, aseptic loosening), infection of the bed of the implant, dislocation of the implants. In the department of general oncology 625 joint replacement 518 patients were performed. Dislocations frequency after prosthetics of a humeral joint was observed in 4,1% (3/73), 7,6% (6/79) - after prosthetics of proximal part of femurs, 18% (7/39) after total replacement with endoprosthesis of the femur. Thus, among all the cases 30,6% (191/625) were endoprosthesis replacement of proximal femoral and humeral bones and total replacement of a femur with endoprosthesis. Currently the intraoperative reconstruction of the capsular apparatus of large joints using synthetic materials is considerable.
