Prostheses for partial hand amputations.

Amputation of part of a hand may create significant functional limitations for the amputee which are difficult to ameliorate by either orthoses or prostheses. To help develop a logical approach to devices for partial hand amputations the patterns of losses have been studied and a division into four categories has been proposed. Transphalangeal, thumb spared; thenar, partial or complete; transmetacarpal, distal; transmetacarpal, proximal. By utilizing basic principles of orthotics and prosthetics and by exercising ingenuity, it is often possible to provide considerable improvement in function and/or cosmesis to individuals with partial hand amputations. Case illustrations and their prosthetic solutions are presented.
