Abstract

A wrist arthrodesis plate (20) consisting of a distal region (21) and of a proximal region (22) which adjoins the distal region (21) in the direction of a longitudinal axis (A). The plate (20) is of such a shape and size that the distal region (21) of the plate can be fastened to the carpus (1) and a proximal region (22) of the plate can be fastened to the radius (3) by fastening devices, such as screws, which can be inserted into plate holes. A distal end region (29), which comprises a farthest distal location (23) of the plate (20), is of a shape and size that the distal end region (29) can be placed with the farthest distal location (23) exactly, and only, on a carpal bone from the group comprising trapezium (11), trapezoid (10), capitate (9) and hamate (8), without covering any part of the laterally adjacent bones.
