Apparatus and method for applying rotational pressure to parts of the body

Apparatus for applying rotational pressure to the hip joints of a human patient, comprising two separate cast means, each being adapted to be placed about a leg of a patient so as to hold such leg against substantial rotation relative to such cast means;

• and means interconnecting the separate cast means adapted to hold the cast means at angles of rotation to one another to thereby put rotational pressure on each hip joint, such interconnecting means including track means secured to at least one of the cast means and extending in a plane perpendicular to the longitudinal axis of the cast means and mating means adapted to be rigidly secured to said track means at points along said track means, securement at different points providing different degrees of rotation of the casts along their longitudinal axises one to another.

Apparatus for applying rotational pressure to the tibia of a human patient comprising two separate cast means, one being adapted to be placed about a portion of the leg of the patient above the ankle so as to hold the upper portion of the tibia against substantial rotation relative to such cast means and the other adapted to be placed about the ankle of the patient so as to hold the ankle and the lower portion of the tibia against substantial rotation relative to such cast means;

• an attachment plate secured to one cast having a plurality of attachment means;
• and a connecting means on the other cast adapted to mate with selected attachment means on the attachment plate, the particular attachment means selected determining the amount of relative rotation between the casts thereby determining the rotational pressure on the tibia.
