The invention belongs to the technical field of orthopedic medical equipment, and particularly relates to a leg fracture reduction device for an orthopedics department. The leg fracture reduction device for the orthopedics department comprises a columnar supporting mechanism, a traction mechanism and a leg supporting mechanism, wherein the traction mechanism is matched with the columnar supportingmechanism; and the leg supporting mechanism is matched with the columnar supporting mechanism and the traction mechanism during supporting. The upper part of a fracture part is pre-fixed in the peripheral direction, dragging is carried out by the traction mechanism, finally, gradual pushing reduction is carried out, the problem that the traction force cannot be controlled in the prior art is avoided, medical risks in a reduction process are reduced effectively, and controllability in a treatment process is improved. Meanwhile, by the supporting mechanism, the circumstance that the body of a patient shakes due to local supporting to cause failing of the device is avoided.
