The invention relates to the technical field of fracture traction and reposition medical instruments, and in particular relates to a fracture traction device, used for fracture traction and reposition of an arm. The fracture traction device includes a traction platform, a fixing mechanism for fixing the arm of a patient, and a traction mechanism for applying traction on the arm of the patient. According to the fracture traction device, the fixing mechanism is used for fixing the arm of the patient, and cooperating with the traction mechanism for applying traction on the fracture part of the arm of the patient, so that difficulty during a traction process is reduced and traction time consumption is reduced; a universal structure is arranged on the traction mechanism of the fracture traction device, the traction direction or the traction angle can be randomly adjusted during the traction process, and the fixing position of the arm of the patient and the position of the traction device do not need to be adjusted; the fracture traction device provided by the invention is simple in structure, small in occupied space and applicable to using in small hospitals or homes.
