The Scheker Prosthesis

We now have a new prosthesis and method of treating loss of pronation and suppination caused by incongruity of the joint between the radius and ulna (the radioulnar joint ) of the wrist. Movement in the palm up and palm down motion of the wrist is called pronation and suppination. Pronation is when you turn your palm down toward the floor and suppination is when you turn your palm up toward the sky.
