ABSTRACT OF THE DISCLOSURE In accordance with the present invention, there is provided a portable hand mounted device for tractioning a finger having a fractured bone and at the same time continuously flexing and extending the joint to which the fractured bone is proximally attached in order to prevent joint deterioration. More particularly, the device may be made in an inexpensive manner by medical personnel and is a light, less cumbersome device than that in the prior art. A drive motor is carried by a cast-like support which is attachable to the forearm and hand for substantially immobilizing the wrist joint and joints of the hand proximal to the joint which is immediately proximally connected to the broken bone. The support carries a frame or hoop defining a substantially arcuate path of motion for carriage travel while flexing and extending the joint of the fractured finger. The carriage rides on the hoop first in one direction and then in the other direction along the arcuate path. The carriage is driven by an elongated, flexible yet stiff cable mounted for travel in a guide in the hoop with one end of the cable connected to the drive motor to push and pull the cable in the groove and to reciprocate the carriage. Elastomeric bands tension the broken finger to the carriage so that the finger joint follows the reciprocating carriage to first extend the finger, bending occurring primarily at the proximally connected joint.
