Method of performing a tendon replacement
A method of performing a tendon replacement, of a tendon connecting a first bone and a second bone, in an animal body utilizing a suture assembly that includes the following construction. A button has two apertures and a suture, engaged to the button, defines a lumen and forms a double loop, formed by a double trap that is opposed to the button. The suture assembly further defines a first single trap, and a third trap. In the method, a drill hole is drilled sequentially through the two bones. Also, a length of tendon tissue is draped over the loop and the button is passed through the drill hole through the first bone and the second bone and the button is oriented to sit on a surface of the second bone and the suture ends extend outwardly through the drill hole.
1. A method of performing a tendon replacement, of a tendon connecting a first bone and a second bone, in an animal body:
(a) drilling a drill hole sequentially through said two bones;
(b) providing a suture assembly, including:
(i) a button having two apertures;
(ii) 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 of said double trap portion and a second portion of said suture is also threaded through said lumen of said double trap portion, so that two portions of suture are positioned together in said double trap and further wherein said first portion of said suture, after emerging from said second end of said double trap, is threaded through said lumen again, thereby increasing resistance of said double loop to expansion, after it has been tightened;
(c) draping lengths of tendon tissue over said double loop and passing said button through said drill hole through said first bone and said second bone, and orienting said button to sit on a surface of said second bone and the suture ends extend outwardly through said apertures of said button;
(d) pulling on said suture ends, to constrict said double loop.
2. The method of claim 1 , wherein said button includes an additional aperture and wherein a thread is engaged with said additional aperture and said thread is used to pull said button through said drill hole.
3. The method of claim 2 , wherein said button includes at least one additional aperture, and wherein a further thread is engaged to said additional aperture and used to position said button.
4. The method of claim 1 , wherein said first bone is a tibia and said second bone is a femur.
5. The method of claim 1 , wherein said animal body is a human body.
6. The method of claim 1 , wherein said button is oblong, and is passed through said drilled hole so that the narrowest dimension of said button faces said drilled hole.
7. The method of claim 1 , wherein said suture is banded, to help a health care professional performing said method to gauge length.
8. The method of claim 1 , wherein said first portion of said suture, after emerging from said second end of said double trap, is threaded through said lumen again, by being threaded into and out of a portion of said lumen on a first side of said double trap, thereby forming a second trap, additional to said double trap.
9. The method of claim 8 , wherein said second portion of said suture, after emerging from said first end of said double trap, is threaded into and out of a portion of said lumen on a second side of said double trap, opposed to said first side, thereby forming a third trap, additional to said double trap and said second trap.
