- a first, proximal section configured to be connected to the radius bone;
- and
- a second, distal section configured to be connected to at least one metacarpal bone, wherein:
- each section defines a part of a curved bearing, with the part defined by said first, proximal section including a convex surface and the part defined by said second, distal section including a concave surface which engages said convex surface,
- said second, distal section includes a carpal plate in which at least one element is journaled for connection to said at least one metacarpal bone,
- said carpal plate includes a seat,
- said second, distal section further includes a screw connected to the metacarpal bone,
- said screw having a head, and
- said head is received by said seat.
