The Fryette laws are a set of three laws regarding skeletal anatomy that guide osteopathic medicine practitioners to identify various dysfunctions in the axial skeleton. These laws are named after Harrison Fryette, D.O, an osteopathic practitioner who established them.

The first law states that when the spine is in a neutral position, side bending to one side is accompanied by rotation on the opposite side. The second law states that when the spine is in a non neutral position, such as flexed or extended position, side bending to one side is accompanied by rotation on the same side. The third law states that if motion is initiated at a vertebral segment in one plane, it will limit the mobility of the segment in the other two planes.
