Abstract
The artificial joint part consists of a distal spherical bearing member (1), which can be attached by attachment means (16) to the capitate bone (14) or/and hamate bone (15), and also of a platform (18), which is attached to the radius (6) and at right angles to the longitudinal axis (7) of the radius (6) towards the ulna (8) comprises a guide surface (5). An intermediate member (2) is supported at the proximal end with a sliding surface (4) on the guide surface (5) and is displaceable in the direction of the ulna (8), whereas at the distal end it forms a spherical bearing (3) for the bearing member (1).
