Abstract: An orthopedic limb interface device is disclosed for positioning and retaining a lower portion of the arm of the human body during orthopedic operatory procedures. The device includes a handplate coupled to a sleeve. The sleeve surrounds and grips the arm and is lined with an inflatable bladder. The bladder includes a plurality of inflatable zones, at least one zone having inflation limiting means such that the inflated bladder has a variable inflation profile therealong. The variable inflation profile is configured to increase retention at target areas of the limb, while softly retaining other areas of the limb to avoid limb numbness. Areas of increased retention may engage portions of the arm to improve the grip on the arm for reliable limb distraction.
