Thumb Metacarpophalangeal Joint Arthrodesis
Fixing the thumb in a position of palmar abduction is an operation of last resort. It is reserved for those cases of paralysis in which there are no transferable muscles, where there are spastic paralysis and adduction contracture, and where there is severely scarred thumb-web space but in which there is still some chance for useful hand function if the thumb can be placed in an abducted position (Figs. 48-1 A Figs. 48-1 B Figs. 48-1 C-I).
