The invention shows an artificial finger joint comprising a convex joint head (1) and comprising a concave joint shell (2) which can be fastened independently of one another with a respective shaft (3, 4) in a bone end (5, 6) and which can be moved in an articulation plane from an extension position (7) with parallel shaft axes (8, 9) into a hyperextension position (10) or into an articulation end position (11). A guide pin (12) projects out of the joint shell (2) in the direction of its shaft axis (9) and protrudes into a pocket (13) of the joint head (1), with the pocket (13) having a first abutment (16) for the guide pin (12) in the hyperextension position (10). A second abutment (17) between the joint shell (2) and the joint head prevents a tilting of the guide pin (12) and shaft (4) of the joint shell (2) about the first abutment (16) in the hyperextension position (10).
Artificial finger joint comprising a convex joint head (1) and comprising a concave joint shell which can be fastened independently of one another with a respective shaft (3, 4) in a bone end (5, 6) and which can be moved in an articulation plane from an extension position (7) with parallel shaft axes (8, 9) into a hyperextension position (10) or into an articulation end position (11), characterized in that a guide pin (12) projects out of the joint shell (2) in the direction of the shaft axis (9) of the latter and protrudes into a pocket (13) of the joint head (1), with the pocket (13) having a first abutment (16) for the guide pin (12) in the hyperextension position (10);
