ABSTRACT:
A surgically implantable prosthetic phalangeal joint replacement device which allows twisting, pistoning, flexing, and lateral rotational movement made up of a ball joint held within a receptacle end defining a socket with enlarged or recessed sides, thereby allowing flexing and lateral rotational movement. Twisting and pistoning movement is achieved by a metacarpal body which interconnects the bones to be joined and rotatively and slidably connects to the ball joint. A pin can be used to securely retain the device together and allow the aforementioned range of motion.
