Suture system and related methods for connecting and creating suspension between at least two bodies
A suture suspension system including a flexible backstop extending along a longitudinal axis and having two ends positioned in a first direction in an undeployed configuration. A length of suture can be positioned through the flexible backstop and forms a bridge connecting and creating suspension between a first body to a second body. In a deployed configuration, the two ends of the flexible backstop are positioned in a second direction different from the first direction. The system may also include an anchoring body having the length of suture woven therethrough. A portion of the anchoring body is positioned on a distal surface of a second body and a portion of the flexible backstop is positioned on a proximal surface of the first body.
1. A method of securing a first body in relative position to a second body, the method comprising the steps of:
providing a suture system comprising a length of suture with a pair of free limbs each of which has a free end and is positioned through an all suture anchoring body;
drilling a first single hole through a first proximal body and a second single hole through an adjacent second distal body, wherein the first proximal body comprises bone and the second distal body comprises bone and wherein the first hole and the second hole are in alignment;
positioning the anchoring body on a distal surface of the second distal body;
passing the free limbs from the anchoring body through the second hole in the second distal body and to and through the first hole of the first proximal body;
passing the free limbs through an all suture flexible backstop;
moving the flexible backstop distally along the length of suture to a proximal surface of the first proximal body, wherein the distal surface faces a distal direction and away from the proximal surface; and
pulling the free limbs having the free ends to position the flexible backstop in a deployed configuration.
2. The method of claim 1 , further comprising the step forming a knot in the length of suture proximal the flexible backstop.
3. The method of claim 1 , wherein the step of passing the free limbs through a flexible backstop, which extends along a longitudinal axis and has two ends positioned in a first direction in an undeployed configuration includes the steps of:
inserting the free limbs through a pair of loading loops; and
pulling the loading loops through the flexible backstop.
4. The method of claim 1 , wherein at least one of the first body and the second body is a bone.
5. The method of claim 1 , further comprising the step forming a knot in the length of suture proximal the flexible backstop.
6. The method of claim 1 , wherein the flexible backstop has a longitudinal axis and two ends positioned in opposite directions along the longitudinal axis in an undeployed configuration.
7. The method of claim 6 , wherein the two ends of the flexible backstop are positioned in the same direction in a deployed configuration.
8. The method of claim 1 , wherein the flexible backstop has a longitudinal axis and wherein the step of pulling expands the flexible backstop in a direction perpendicular to the longitudinal axis.
