Tri-lock adjustable button loop
A suture assembly, including a button having two apertures and a suture defining a lumen and forming a double loop, formed by a double trap having a first end and a second end, opposed to the button. A first portion of the suture is threaded through the trap from the first end to the second end, and a second portion of the suture is threaded through the trap from the second end to the first end. The assembly further defines a first single trap, in which the first portion of the suture is threaded through the lumen between the second end and the button. Also defined by the assembly is a third trap, in which the second portion of the suture is threaded through the lumen between the first end and the button. Finally, the double loop is threaded through the two apertures of the button.
1. A suture assembly, comprising:
(a) a button having two apertures;
(b) a suture defining a lumen and forming a double loop, formed by a double trap having a first end and a second end, formed in a double trap portion of said suture, opposed to said button, and in which a first portion of said suture is threaded through said lumen in said double trap portion of said suture, from said first end to said second end, and a second portion of said suture is threaded through said lumen in said double trap portion of said suture from said second end to said first end and further defining a first single trap, in which said first portion of said suture, after emerging from said second end of said double trap, is threaded through said lumen between said second end and said button and a third trap, in which said second portion of said suture, after emerging from said first end of said double trap, is threaded through said lumen between said first end and said button, said double loop being threaded through said two apertures of said button; and
(c) wherein said suture has a first suture end and a second suture end and wherein said suture ends are threaded through said apertures of said button and are accessible on a side of said button opposed to said double loop.
2. The suture assembly of claim 1 , wherein said button has additional apertures that are free of sutures and available to be coupled to a thread during surgery.
3. The suture assembly of claim 2 , wherein said additional apertures are arranged symmetrically about said two apertures.
4. The suture assembly of claim 1 , wherein said suture is made of ultra-high molecular weight polyethylene.
5. The suture assembly of claim 1 , wherein said button is rectangular with rounded ends.
6. The suture assembly of claim 1 , wherein said double loop can be constricted by pulling on said suture ends.
