<p>A finger joint prosthesis is provided including a joint body having first and second joint elements, which are connected together pivotably about a rotary axis and from each of which extends an anchoring bar for fixing to a proximal and/or distal phalanx. The anchoring bars have eyes with openings for receiving fixing screws. To increase stability, it is proposed that the first joint element have an external hollow body with an insertion opening that the second joint element have an internal hollow body, and that the internal hollow body in the position of installation can be inserted by way of the insertion opening relatively movably into the external hollow body. A spindle can be inserted in the position of installation into the internal hollow body for rotationally movable connection to the external hollow body.</p> |
