Adolescent pelvic chondrosarcoma, surgical treatment, and unusual reconstruction with pedestal conic cup (LUMIC®) A case report

An 18-year-old male patient was diagnosed pelvic chondrosarcoma histopathologically. Hip joint involvement was detected. No metastasis or neurovascular invasion was seen. Type I+II pelvic resection and hip reconstruction were planned with pedestal cup (LUMIC (R)) and proximal femur tumor prosthesis. Surgery was performed in lateral decubitus position with extensive triradiate incision. Pelvic wide resection was performed. At the second year of follow-up, implant failure was detected and patient was revised with same pedestal cup. Axial stability was supported by a 1.5 screw and connector from 1.5 vertebrae to LUMIC (R) prosthesis. Except the implant failure. no oncological complication or infection was observed during the final 36th month follow-up.
