Lead hands and aluminum hands are malleable hand-shaped slabs that are used to position the hand during hand surgery. The flexible fixation device can be positioned in any way preferred by the surgeon and secured with the tab-like finger restraints or by other methods. They can be used with either the left or right hand and are available in adult and pediatric sizes. The Tupper's Hand Universal Retractor system features a keyhole-shaped table upon which the hand is placed and secured with a system of rubber bands, tendon hooks, and ball chains and chain holders.
