An apparatus including a bar (9) controlled by the rod of a hydraulic cylinder (4) and supporting a cradle (10) for a patient's leg. The cradle-supporting bar is attached to the end of a crank arm (8) coupled to the rod (5) of the hydraulic cylinder (4) via coupling means (6, 7) arranged in such a way that sliding movement of the cylinder rod causes rotation of the crank arm about a pivot pin (7) until the patient's leg is in the desired position. |
