The invention discloses a tibial plateau back edge dissecting hook steel plate. The two ends of the head of a bone fracture fixation plate outwards extend; the two end parts are in a circular arc shape and form a fixed plate; two tibia hooks are arranged on the vertical plate surface of the middle part of the fixed plate; screw holes are formed in the vertical direction of the bone fracture fixation plate; and screw holes are uniformly distributed and formed in the transverse direction of the plate surface of the fixed plate. The plate surface of the bone fracture fixation plate is not a flat surface, and the center position of the bone fracture fixation plate is slightly projected. The upper end of each of the two hooks is in a sharp shape; and the lower end of each of the two hooks is gradually enlarged to be integrally in a triangular shape. The tibial plateau back edge dissecting hook steel plate has the advantages that the structure is simple; the fixation is firm; the operation is convenient; and the tibial plateau back edge dissecting hook steel plate can be used for effectively fixing tibial plateau back edge bone fracture and cruciate ligament avulsion fracture.
