PuzzleCast - A Recovery-Accelerating Modular Cast From: Popular Science - 06/2012 - page 60 By: Lauren Aaronson The cast consists of six pieces that can be removed independently, enabling patients to move more parts sooner. The device has six removable pieces. Two pieces brace the forearm and hand, keeping the broken limb stable. The rest restrict each of the lower arm's four movements: the bending of the elbow and the up-down, side-to-side and twisting of the wrist. A cast technician assembles the kit by putting the heat-moldable plastic in hot water, shaping the cast around the patient’s arm, and snapping in rivets to fasten the pieces.
