Abstract
A trapezial implant is provided for attachment to the trapezium of a hand. The implant includes a base member fabricated from an inelastic material such a medical grade metal or ceramic. The base member includes a generally planar proximal attachment surface from which extend two pentihedral-shaped spikes. The base member also includes a distal articular surface having a non-symmetrical, complex curvature. The implant is retained in place on the trapezium under compression of the first metacarpal.
