Suture locking loops and method of use
View Patent ↗A one-way loop locking suture assembly, that includes suture material, defining a lumen, with the suture material being comprised of a first terminal portion extending from the first end to a first broaching point, a medial portion extending from the first broaching to a second broaching point and a second terminal portion extending from the second broaching point to the second end. The first terminal portion enters into the lumen of the medial portion at the second broaching point, extends through the lumen of the medial portion and exits the lumen of the medial portion through the first broaching point, thereby forming a loop, wherein the medial portion includes the first terminal portion extending through the lumen of the medial portion. Accordingly, when the loop is tightened about a pair of pins, the lumen of the medial portion narrows, thereby retaining the first terminal length and preventing loosening.
1. A method of repairing a leg joint, including a femur and a tibia, and comprising:
(a) providing a first bone screw and a second bone screw;
(b) providing a suture assembly including:
(i) suture material, defining a lumen, said suture material having a first end and an opposed second end, and being comprised of a first terminal portion extending from said first end to a first broaching point, a medial portion extending from said first broaching to a second broaching point and a second terminal portion extending from said second broaching point to said second end; and
(ii) said first terminal portion entering into said lumen of said medial portion at said second broaching point, extending through said lumen of said medial portion and exiting said lumen of said medial portion through said first broaching point, thereby forming a suture loop, wherein said medial portion includes said first terminal portion extending through said lumen of said medial portion;
(c) screwing said first bone screw into said femur;
(d) screwing said second bone screw into said tibia; and
(e) placing said suture loop about said two screws and pulling said first and second ends until said suture loop is cinched tight, thereby causing said lumen of said medial portion to narrow, thereby retaining said first terminal length and preventing loosening, so that said loop is locked in size, and coupling said screws and thereby said femur and tibia together.
2. The method of claim 1 , further wherein said second terminal portion enters into said lumen of said medial portion at said first broaching point and extends through said lumen of said medial portion and exits said lumen of said medial portion through said second broaching point, thereby forming a second loop, and wherein both loops are placed about said two screws.
3. The method of claim 2 , further wherein said first terminal portion re enters into said lumen of said medial portion at said second broaching point, extends through said lumen of said medial portion, a second time, and exits said lumen of said medial portion through said first broaching point, a second time, thereby forming a third loop, and wherein all three are placed about said two screws.
4. The method of claim 3 , further wherein said second terminal portion re enters into said lumen of said medial portion at said first broaching point and re-extends through said lumen of said medial portion and re exits said lumen of said medial portion through said second broaching point, thereby forming a fourth loop, and wherein all four loops are placed about said two screws.
5. The method of claim 1 , wherein said leg joint is more specifically a dog stifle.
6. The method of claim 1 , wherein the cranial cruciate ligament has been damaged.
