Conservative treatment of humerus fracture, there are the following four steps: first, manipulation of reset, first of all, the use of plucking and stretching hand method, the overlap of the broken end of the fracture, displacement to give the correction, generally proximal an assistant with a traction belt upward traction, the distal end of the assistant hand holding the forearm downward traction. The first homeopathic traction, along the longitudinal axis of the limb for traction, overlap, displacement correction, after the use of end lifting and pressing the corrective maneuver, to correct the fracture of the anterior, posterior, left, right lateral displacement. If there is rotational displacement, the assistant at the distal end of traction will rotate the fracture clockwise or counterclockwise. If there is angular displacement, correct the angulation using a press-on maneuver. Two or three pads are used to fixate around the limb, either flat pads or tower pads can be used. Secondly, fixation, put four splints around the limb in front, back, left and right, and use four ties to fix it in the middle, then in the distal end, and then in the proximal end. Third, medication, early take blood circulation and eliminate blood stasis, swelling and pain medication, middle take bone grafting Dan, late take liver and kidney tonic, strengthen the muscles and bones of the drug. Fourth, functional exercise, early contraction of the upper arm muscles, medium-term flexion, extension and rotation of the shoulder and elbow joints, and later functional activities in all directions, until the normal function is restored.
