Internal fixation method of macaque long bone defect model

The invention discloses an internal fixing method of a macaque long bone defect model, and belongs to the technical field of macaque long bone defect model.The macaque long bone defect model is fixed, an arc-shaped metal fixing plate is adopted to fix a macaque long bone, and a center line mark perpendicular to the long axis direction of the fixing plate is arranged in the middle of the arc-shaped convex face of the fixing plate; the arc-shaped concave face of the fixing plate is attached to the surface of the middle section of the long bone of the macaque, a plurality of screw holes are formed in the fixing plate, and the fixing plate and the long bone of the macaque are fixedly connected through the screw holes and screws. The fixing plate is accurately attached to the surface of the long bone of the macaque, the midpoint of the long bone of the macaque and the midpoint of the osteotomy range can be relatively positioned through the arranged midline mark of the fixing plate, after the midline-midpoint is po
