Abstract
A method of surgically repairing an injured human joint such as a finger joint by means of a prosthetic device. The prosthetic device comprises a U-shaped sack partially filled with a pressure sensitive material. The prosthetic device is implanted between two bones comprising the injured joint in a manner to control the growth of the scar capsule at the joint to prevent the joint from becoming stiff. The pressure sensitive material in the sack moves between the two bones in response to any slackness of the scar to fill out the slackness and thereby prevent shortening of the scar that would restrict motion.
Claims5
A method of surgically repairing an injured human joint with a prosthesis including the steps of providing a prosthesis comprising a balloon-like device having a U-like configuration and constructed of a synthetic, elastomeric material having a biologically tolerable material having a preselected pressure sensitive material partially filling the balloon, reshaping the injured tissues surrounding the joint, providing a space between the two opposing surfaces of the bones of said joint, positioning within said space said prosthesis and completely filling the joint space therebetween to maintain the distance between the two bone surfaces thereby permitting normal movement at said joint to thereby control the growth of new scar tissue around the joint during healing to prevent the new scar tissue from shrinking around the joint in a manner so as to restrict the normal movement of the joint after it healed.
