Femoral fractures were created in rats to determine whether there were differences in healing under conditions of immobilization and under conditions of immediate weight-bearing. Histologic and roentgenographic differences were present by the second week after fracture and differences became progressively greater during the next 3 wk. Functional weight-bearing was found to accelerate the rate of fracture healing and to improve significantly the strength of the healing bone.
