For Deformed Arm

No. 324, page 66, represents irregularly formed forearm and hand, the forearm being considerably shorter than the opposite one. No. 325 represents artificial arm and hand made to supply the deficiency. The hand may be wood or rubber and detachable or not at the wrist, and provision made for the use of implements the same as in case of an amputation. These malformations are treated mechanically the same as amputations. Plaster moulds or casts of the deformed parts are required, together with measurements of the opposite arm and hand.

Manner of Attaching Arm and Straps

No. 326 illustrates arm for amputation below the elbow, equipped with shoulder cap, strap passing around body for holding it in place, and the attachment for opening the thumb by movement of the opposite shoulder. If thumb is to be opened with the assistance of the sound hand, this extra strap and traction rod are omitted.
