Abstract: Apparatus for applying rotational pressure to one or more selected parts of the body of a patient includes at least two separate casts placed about portions of the patient's body so as to hold such portions against substantial rotation relative to such casts and interconnections between the separate casts adapted to hold the casts at selected angles of rotation to one another to thereby put rotational pressure on the selected parts of the body. A method for applying rotational pressure to one or more selected parts of the body includes the steps of casting portions of the body, rotating the casts with respect to one another, and locking the casts together in rotated position to thereby place rotational pressure on the selected portion of the body.
