Different biological reconstruction methods (the arrows show the involved bone). A. Intercalary devitalized bone by anhydrous alcohol and fixed by a unilateral plate in an 18 years old female Ewing sarcoma patient at proximal humerus. B. Intercalary devitalized bone by radiation with fibular and fixed by a unilateral plate in a 15 years old male osteosarcoma patient at distal femur. C. Osteoarticular devitalized bone by liquid nitrogen with fibular and fixed by a bilateral plate in a 25 years old male osteosarcoma patient at distal femur. D. Intercalary fibular segments and fixed by a bilateral plate in a 23 years old female osteosarcoma patient at the proximal tibia. E. Intercalary allograft replacement fixed by an interlocking intramedullary nail in a 14 years old male osteosarcoma patient at distal femur. F. Intercalary allograft replacement fixed by an interlocking intramedullary nail in a 17 years old male osteosarcoma patient at the proximal tibia. G. Osteoarticular allograft replacement fixed by an interlocking intramedullary nail in 14 years old male osteosarcoma patient at distal femur. H. Osteoarticular allograft replacement fixed by a unilateral plate in 32 years old female osteosarcoma patient at proximal humerus.
