Abstract
Surgical fixation assemblies include a screw-in anchor with a suture construct attached to and extending through an interior of the anchor. The suture construct has two finger trap splices to trap suture that has been passed through them when the construct is placed in tension. Transfer sutures containing loops are preloaded through the finger trap splices and used to pull the ends of the repair sutures through the finger trap splices to form reducing loops around or through captured tissue.
Claims20
A surgical fixation assembly comprising:
- an anchor comprising:
- a proximal end, a distal end, and threads extending in an open helical form from the proximal to the distal end;
- at least one rib extending through an interior of the anchor;
- and
- a suture bridge extending at least partially through the interior of the anchor;
- and
- a suture construct comprising:
- a repair suture having a first repair leg and a second repair leg;
- a first transfer suture coupled to the first repair leg via a first constriction element, a first end of the first transfer suture comprising a first free end and a second end of the first transfer suture comprising a first transfer loop;
- and
- a second transfer suture coupled to the second repair leg via a second constriction element, a first end of the second transfer suture comprising a second free end and a second end of the second transfer suture comprising a second transfer loop;
- wherein the suture construct is coupled to the suture bridge such that the first repair leg, the second repair leg, the first transfer suture and the second transfer suture extend through the interior of the anchor.
A method of tissue repair comprising:
- inserting an anchor of a surgical fixation assembly into a first tissue, the surgical fixation assembly comprising:
- the anchor comprising:
- a proximal end, a distal end, and threads extending in an open helical form from the proximal to the distal end;
- at least one rib extending through an interior of the anchor;
- and
- a suture bridge extending at least partially through the interior of the anchor;
- and
- a suture construct comprising:
- a repair suture having a first repair leg and a second repair leg;
- a first transfer suture coupled to the first repair leg via a first constriction element, a first end of the first transfer suture comprising a first free end and a second end of the first transfer suture comprising a first transfer loop;
- and
- a second transfer suture coupled to the second repair leg via a second constriction element, a first end of the second transfer suture comprising a second free end and a second end of the second transfer suture comprising a second transfer loop;
- passing the first repair end around or through a second tissue and through the first transfer loop;
- and
- using the first free end of the first transfer suture, pulling the first repair end through the first constriction element to form a first reducible loop around or through the second tissue;
- wherein the first constriction element is configured to allow the first reducible loop to be tightened but not loosened around or through the second tissue.
