Abstract
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.
