BODY PART SUPPORT DEVICE AND METHOD
A device and method for supporting a body part by another body part. The device includes a first (or proximal) button, a second (or distal) button, and a suture connecting the first button to the second button, with there being a space between the first button and second button. An opening is formed through two body parts, and the second button and suture are moved through the opening until the second button is outside of the opening and is seated against the outer (distal) side of the second body part. The first button is then seated against the outer (proximal) side of the first body part, so that one of the body parts provides support for the other. The first button may be attached to the suture after the second button is seated on the distal side of the second body part.

(i) forming an opening through a first metacarpal, the first metacarpal having a first proximal side and a first distal side, and a second metacarpal, the second metacarpal having a second proximal side and a second distal side;
(j) providing a device comprising a first button, a second button having a first position and second position, and a suture connected to at least the second button;
(k) passing the suture and second button through the opening so that the second button moves past the second distal side, where the second button moves to its second position, so the second button seats against the second distal side; and
(l) seating the first button against the first proximal side.

17 . The method of claim 1 , wherein the first button has at least one hole to which the suture attaches.
18 . The method of claim 1 , wherein the first button has a plurality of holes to which the suture attaches.
19 . The method of claim 15 , wherein the second button has at least one hole to which the suture attaches.
20 . The method of claim 16 , wherein the second button has a plurality of holes to which the suture attaches.
21 . The method of claim 1 , wherein the first button is attached to the suture prior to passing the suture and second button through the opening.
22 . The method of claim 1 that further comprises the step of adjusting the distance between the first metacarpal bone and the second metacarpal bone after the second button moves to the second position.
23 . The method of claim 21 that further comprises the steps of unattaching the suture from the first button and reattaching the suture to the first button in order to seat the first button to the first proximal side.
24 . A device for supporting a body part by another body part, the device comprising:
(d) a first button;
(e) a suture having a first and second end;
(f) a second button attached to the second end of the suture, the second button having a first position and a second position.
25 . The device of claim 24 , wherein the first button and second button comprises one or more of plastic and metal.
26 . The device of claim 24 , wherein each button has a length between ⅛″ ½″.
27 . The device of claim 24 , wherein each button has a width between 1/64″ and ⅛″.
28 . The device of claim 24 , wherein each button has a width between ¼″ and ⅛″.
29 . The device of claim 24 , wherein each button has a thickness between 1/64″ and ⅛″.
30 . The device of claim 26 , wherein each button has a thickness between 1/64″ and ⅛″.
