The radius 31 is provided with a fracture line 4 at one side close to the metacarpal bone 33, the fracture line 4 divides the radius 31 into a fracture distal end 312 and a fracture proximal end 311, and the fracture reduction model further comprises a fracture fixation device 1 for connecting and reducing the fracture distal end 312 and the fracture proximal end 311.
It should be noted that, the hand bone model 3 is made of opaque materials, which is favorable for developing the hand bone model 3 under the X-ray, and may be a metal material or a rigid polymer material mixed with developing elements, for example, a polymer material such as PEEK or nylon mixed with elements such as tungsten, platinum, barium, etc., and the simulated skin 2 encapsulates the whole hand bone model 3 to simulate skin tissue, and may use an elastic material such as silicone rubber, etc., so that the encapsulated state of the skin on the fractured radius 31 may be simulated more truly.
Working principle: when the fracture part of the radius 31 needs to be reduced, the fracture distal end 312 is pulled to be close to the fracture proximal end 311, then the fracture proximal end 311 is lifted up, so that the fracture distal end 312 and the fracture proximal end 311 are in reduction contact, and finally the fracture distal end 312 and the fracture proximal end 311 are fixed through the fracture fixing device 1.
