Implanted bone fracture in different biological reconstruction methods (the arrows show the fracture site). A. Shift fracture of osteoarticular allograft at 24 months after surgery in a 13 years old male osteosarcoma patient at proximal humerus. B. Metaphysis fracture and condyle collapse of osteoarticular devitalized bone at 18 months after surgery in an 11 years old female osteosarcoma patient at distal femur. C. Epiphysis slippage and condyle collapse of osteoarticular devitalized bone at 20 months after surgery in an 8 years old female osteosarcoma patient at the proximal tibia. D. Fibular segments fracture at 4 months after surgery in a 17 years old male osteosarcoma patient at proximal humerus. E. Condyle fracture of osteoarticular devitalized bone at 12 months after surgery in an 18 years old male osteosarcoma patient at distal femur. F. Metaphysis fracture and head absorption of total humerus devitalization at 28 months after surgery in a 23 years old female osteosarcoma patient. G. Condyle fracture of osteoarticular devitalized bone at 12 months after surgery in a 19 years old male osteosarcoma patient at distal femur. H. Condyle fracture of osteoarticular devitalized bone at 16 months after surgery in a 14 years old female osteosarcoma patient at the proximal tibia.
