Abstract
This invention is a suture anchor system for securing a suture (17, 18, 19), into a bone cortex (10) surface. The system includes forming a hole (14, 15, 16) into a bone cortex surface that is of a diameter and depth to provide a wall surface area that is at least as great as the surface area of an end section of a suture or sutures fitted therein. By filling the hole with an adhesive (24) that is allowed to cure, a suture mounting is provided that will have a pullout strength or purchase that is greater than a load as is anticipated to be applied thereto. To increase the purchase a portion of the hole formed into the bone cortex may be counter bored to form an outwardly extending skirt, the suture may be folded upon itself, a knot may be tied in the suture, or a pair of sutures can be combined together.
Claims
1. A suture anchor system comprising, at least one suture means having a straight end section for fitting into a hole formed into a section of a bone whereat said suture means is to be attached to extend axially therefrom, with said suture means straight end section having a surface area that is at least slightly less than the interior surface area of said hole; and an adhesive that is selected to be suitable for implantation in a human body and for adhering or interdigitating into the surfaces of both said suture means straight end section and hole interior wall surface to form a bond therebetween, with said suture means extending at approximately a right angle from said adhesive surface, and with said adhesive resisting said suture means being pulled therefrom when a tensile force is applied to said suture means.
2. A suture anchor system as recited in Claim 1, wherein the suture means is a single suture having a straight end section to fit in the hole.
3. A suture anchor system as recited in Claim 2, wherein the single suture is bent upon itself, and said suture bend is fitted into the bone hole.
4. A suture anchor system as recited in Claim 2, wherein a knot is formed in the single suture straight end section that is for fitting in the bone hole.
5. A suture anchor system as recited in Claim 1, wherein the suture means is a pair of sutures.
6. A suture anchor system as recited in Claim 5, wherein the pair of sutures are twisted or braided together.
7. A suture anchor system as recited in Claim 5, wherein the pair of sutures are bent upon themselves, and said pair of sutures bend is fitted into the bone hole.
8. A suture anchor system as recited in Claim 5, wherein a knot is tied in an end section of said pair of sutures for fitting into the bone hole.
9. A suture anchor system as recited in Claim 1, wherein the hole is formed to have a wall surface area that is a minimum slightly greater than the surface area of the suture means straight end section installed therein.
10. A suture anchor system as recited in Claim 9, wherein the hole has an entry diameter which is smaller than a diameter of said hole wall surface.
11. A suture anchor system as recited in Claim 1, wherein the adhesive is a biocompatible bone cement or adhesive.
12. A suture anchor system as recited in Claim 1, wherein the adhesive is a light cured resin.
13. A process for anchoring at least one suture to a bone section consisting of, forming a hole into a bone, with said hole having a diameter and formed to a depth to provide an inner wall surface area that is at a minimum slightly greater than the surface area of an end section of a suture to be fitted therein; positioning an end section of at least one suture in said formed hole; and filling said suture containing hole with an adhesive material.
14. A process as recited in Claim 13, further including forming the hole into a bone material to have an outwardly sloping portion.
15. A process as recited in Claim 13, wherein an end section of the suture is folded upon itself and said fold is fitted into the hole.
16. A process as recited in Claim 13, further including forming a knot in the end section of the suture that is fitted into the hole.
17. A process as recited in Claim 13, wherein a plurality of sutures are twisted or braided together.
18. A process as recited in Claim 17, wherein an end section of the plurality of sutures is folded upon itself and said fold is fitted into the hole.
19. A process as recited in Claim 17, further including forming a knot in a section of the plurality of sutures that is fitted into the hole.
20. A process as recited in Claim 13, wherein the adhesive material is a biocompatible bone cement, resin or cyanoacrylate.
21. A process as recited in Claim 12, where the adhesive material is a grout, filling adhesive, bone paste, bone plug, or light activated resin material suitable for implantation in a human body.
2 1
22. A process for anchoring at least one suture to a bone section as recited in Claim 13, further including fitting the suture end section axially into the hole and said suture end section forms approximately a right angle to a top surface of said adhesive material.
