Claim:
1. A prosthetic full finger assembly, comprising: a eccentric metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user; a distal coupler; a proximal rocker rotatively coupled between the MCP pivot at a proximal end thereof and the distal coupler at a distal end thereof; an adjustable ring tendon rotatively coupled to the MCP pivot at a proximal end thereof and the distal coupler at a distal end thereof; a ring disposed upon the adjustable ring tendon, the ring configured to receive and retain a residual finger of the user, wherein: the adjustable ring tendon together with the proximal rocker are configured to utilize articulation movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-z plane and about one or more axes parallel to a y axis; the MCP pivot is configured to utilize abduction and adduction movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-y plane and about an axis parallel to a z axis; and further comprising a hand strap configured for attachment to a hand of the user, the MCP pivot rotatively coupled to the hand strap via an articulation joint.
