An endoprosthetic joint formed by head and socket members which are adapted to be implanted in a thumb or a finger and can be suitably snapped together. The socket member is provided with structure exteriorly thereof, such as a pair of outwardly projecting webs disposed on diametrically opposite sides thereof, for permitting the muscles, ligaments and tendons to be sutured to these webs to thereby positionally relate same to the implanted joint, whereby proper balancing in the tensions imposed on the muscles and tendons is achieved during pivoting of the digit.
