Bone anchors for attaching soft tissue to bone include an anchor body having a bore that opens at a proximal end and a suture attachment site in communication with the bore for slidably receiving a suture thereon. In one embodiment, three suture attachment sites are provided by two transverse pins placed within the bore. The bone anchors can be fully threaded and, in one embodiment, can have fine and coarse threads for engaging cortical and cancellous bone tissue, respectively.

1. A bone anchor for use in anchoring one or more tissue securing sutures to a bone of a living organism, comprising: an anchor body having a longitudinal axis and extending between a proximal end forming a proximal face transverse to said longitudinal axis and a distal end forming a fixed distal tip, said anchor body further comprising: a longitudinal bore having a proximal opening at said proximal face;a socket formed in a proximal portion of said longitudinal bore through said proximal opening and configured to receive a correspondingly-shaped driver tool; andthreads on an exterior surface of said anchor body beginning at a periphery of said proximal face and extending toward said distal end;a transverse pin, fixedly and non-removably attached to said anchor body, disposed within and extending across said longitudinal bore at a location distal to said proximal face and fixed relative to said proximal face and said distal tip; anda tissue securing suture looped around said transverse pin and having free ends extending from said proximal opening of said longitudinal bore. 2. The bone anchor as in claim 1, wherein said anchor body comprises stainless steel. 3. The bone anchor as in claim 1, wherein said transverse pin comprises stainless steel. 4. The bone anchor as in claim 1, wherein said anchor body is tapered. 5. The bone anchor as in claim 1, wherein said anchor body has a self-drilling distal end. 6. The bone anchor as in claim 1, wherein said socket is hexagonal. 7. The bone anchor as in claim 1, wherein said longitudinal bore includes a distal portion that is substantially cylindrical and wherein said transverse pin is located within said distal portion. 8. The bone anchor as in claim 1, wherein said threads on said anchor body comprise a threaded portion and wherein said anchor body further comprises a non-threaded portion extending from said threaded portion to said distal end, wherein said non-threaded portion has a length of at least about 20% of a length of said threaded portion. 9. The bone anchor as in claim 1, further comprising a plurality of tissue securing sutures looped around said transverse pin within said longitudinal bore, extending out of said proximal opening, and having free ends. 10. The bone anchor as in claim 1, wherein said transverse pin is substantially straight and perpendicular to said longitudinal bore. 11. The bone anchor as in claim 1, wherein said transverse pin extends into an interior wall of said anchor body defining said longitudinal bore. 12. The bone anchor as in claim 1, wherein said threads on said anchor body comprise a proximal threaded section extending from said proximal end and a distal threaded section extending from said proximal threaded section at least partially toward said distal end, wherein said proximal threaded section provides more threads per unit length than said distal threaded section. 13. The bone anchor as in claim 12, wherein each of said proximal threaded section and said distal threaded section is positioned along said anchor body so that said proximal threaded section is configured to engage hard bone tissue and said distal threaded section is configured to engage soft bone tissue when said anchor body is fully inserted into a bone. 14. The bone anchor as in claim 1, wherein said proximal face is configured to be substantially flush with a bone surface when said anchor body is fully inserted into a bone. 15. The bone anchor as in claim 12, wherein said threads comprise a first flute having a single pitch extending through said proximal and distal threaded sections and a second flute having the same pitch as said first flute in said proximal threaded section but which does not continue into said distal threaded section. 16. The bone anchor as in claim 12, wherein said proximal threaded section comprises fine threads and said distal threaded section comprises coarse threads, wherein said proximal threaded section has a root diameter that is greater than a root diameter of said distal threaded section. 17. The bone anchor as in claim 16, wherein said fine threads have a major diameter that is the same as or greater than a major diameter of said coarse threads. 18. The bone anchor as in claim 1, wherein said distal tip is closed at said distal end. 19. A bone anchor assembly comprising a bone anchor as in claim 1 and a driver configured to be received within said socket of said bone anchor. 20. The bone anchor assembly as in claim 19, wherein said driver includes a hole therethrough through which one or more tissue securing sutures pre-loaded on said bone anchor can be threaded. 21. The bone anchor assembly as in claim 20, wherein said one or more tissue securing sutures are threaded through said hole and into said driver. 22. A bone anchor for use in anchoring one or more tissue securing sutures to a bone of a living organism, comprising: an anchor body extending along a longitudinal axis between a proximal end forming a proximal face transverse to said longitudinal axis and a distal end forming a fixed distal tip, said anchor body further comprising: a longitudinal bore having a proximal opening at said proximal face;a socket formed in a proximal portion of said longitudinal bore through said proximal opening and being configured to receive a correspondingly-shaped driver tool;threads having a single continuous pitch beginning at a periphery of said proximal face and extending from said proximal face toward said distal end; anda fixed, non-removable rigid member, configured for looped attachment of at least one tissue securing suture thereto, in communication with said longitudinal bore and positioned transverse to said longitudinal axis at a location distal to said proximal face and fixed relative to said proximal face and said distal tip; anda tissue securing suture looped around said fixed, non-removable rigid member and having free ends extending from said proximal opening of said longitudinal bore. 23. The bone anchor of claim 22, wherein said fixed, non-removable rigid member is disposed within and extends across said longitudinal bore. 24. The bone anchor of claim 23, wherein said fixed, non-removable rigid member comprises a rigid transverse pin. 25. A bone anchor assembly comprising: a bone anchor as in claim 22; anda driver configured to be received within said socket of said bone anchor and which includes a hole through which one or more tissue securing sutures pre-loaded on said bone anchor can be threaded. 26. The bone anchor assembly as in claim 25, wherein said one or more tissue securing sutures pre-loaded on said bone anchor are threaded through said hole and into said driver. 27. A bone anchor for attachment of tissue to bone, the bone anchor comprising: an anchor body including a longitudinal axis, a distal end forming a fixed distal tip, and a proximal end forming a proximal face transverse to said longitudinal axis, said anchor body further comprising: threads beginning at a periphery of said proximal face, extending toward said distal end, and providing a major diameter of said anchor body;a longitudinal bore extending from a proximal opening at said proximal face through said anchor body toward said distal end;a socket formed in a proximal portion of said longitudinal bore through said proximal opening and being configured to receive a correspondingly-shaped driver tool; anda fixed, non-removable rigid member, configured for looped attachment of at least one tissue securing suture thereto, in communication with said longitudinal bore and at a location fixed relative to said proximal face and said distal tip; anda tissue securing suture looped around said fixed, non-removable rigid member and including a first end and a second end, wherein said first end and said second end of said tissue securing suture extend out of said proximal opening at said proximal end of said anchor body. 28.
