Objective: To produce an experimental animal model of injured articular fracture. Methods: 11rabbits (22 legs) were used to produce the model. With the energy weight of an iron hammar falling down that, the wedge would split a femoral condyle, with the capsula articularis intact. A high speed camera was used to measure the time of the procedure. Another 21 rabbits were used to measure the destructive load, intensity, elastic modulus and other biological characters of femur. Results:18 of 22 legs(82%) were successful to produce the animal model of articular fracture. A comminuted fracture was found in 1 leg, whereas the line of fracture was oblique onto condylus lateralis in 3 legs. The time of the procedure was 8.5 milliseconds and the force was 303.64 Newton, which is more than the horizontal femoral destructive load(131.2Newton). Conclusion: In our procedure, breaking up femoral with popliteal incision will produce a rabbit model of articular fractur.
