Application of reduction brace in intraoperative C-arm fluoroscopy to correct the displacement of femoral shaft fracture which is mainly in lateral displacement a Displacement of the force fracture after the external fixator was placed. b In the lateral position, the application of the reset frame shift was initially corrected. c Further adjustment: the lateral displacement was basically corrected. d After the reset was satisfied, the reset frame was fixed and maintained at the apex of the large trochanter. e Displacement of femoral shaft fractures. f Lateral displacement of the femoral shaft fracture: initial reset under the action of the reduction frame. g Further resetting under the action of the reset frame. h Under the action of the reset frame, the reset was satisfactory. i Under the action of the reset frame, the guidewire was smoothly penetrated
