ABSTRACT:
A finger joint prosthesis, made of metal, has a bearing shell (1) attached to a shaft (2) in the metacarpal and a bearing journal (3) attached to a shaft (5) in the phalange. The bearing journal (3) is designed as a barrel (4), which at right angles to its axis (8) in its center comprises a piece (7) connecting it to its shaft (5). The bearing shell (1) is C-shaped and encloses the barrel (4) with clearance to restrict lateral excursion of the phalange shaft (5), whereas an open area formed by the C-shaped shell restricts the flexion at the connecting piece (7). The C-shaped bearing shell (1) can be forced open when the barrel (4) is inserted because its shaft (2) is divided in the longitudinal direction (13) into two halves (14, 15) by a slit-shaped notch (11) so that the shell and the bearing shell can be engaged by moving them radially towards each other.
