US Patent 7143458 Stabilizer for forearm traction

The arm of a patient undergoing wrist arthroscopy or other procedures that involve traction on the forearm, wrist or hand in a vertical position is immobilized in a device containing a stabilizing arch that can be readily secured to an arm board. The device offers multiple degrees of freedom to accommodate arm boards of different widths and heights, and secures the arm of the patient without attaching anything to the arm that might affect the circulation to the involved extremity.
