Abstract

A surgical fastener system for acromioclavicular (AC) joint dislocations, includes a first fastener having an elongate body, and an inner pair of openings centered on the long axis of the body. A closed loop stitch passes through the openings, and the length of the stitch corresponds to the depth of a passage defined between the top of a first hole bored through a patient'"'"'s clavicle, and the bottom of a second hole bored through the coracoid in axial alignment with the first hole. A second fastener has an elongate body arranged to slide under a portion of the loop stitch that protrudes from the top of the hole in the clavicle, after the first fastener is set beneath the coracoid and the stitch is pulled upward through the passage. In an alternate embodiment, the second fastener also has an inner pair of openings for passing and engaging the loop stitch.

Claims

1. A surgical fastener system for treatment of acromioclavicular (AC) joint dislocations, comprising:

a first fastener including an elongate fastener body having an outer pair of openings formed in the vicinity of opposite ends of the body, and an inner pair of openings formed between the outer pair of openings;

an endless or closed loop stitch a portion of which passes through the inner pair of openings in the fastener body, wherein the loop stitch has a length that corresponds to a measured depth of a passage defined between a top opening of a first hole bored through a patient'"'"'s clavicle, to a bottom opening of a second hole bored through the patient'"'"'s coracoid in axial alignment with the first hole; and

a second fastener including an elongate fastener body having at least an outer pair of openings formed in the vicinity of opposite ends of the body;

wherein the body of the second fastener is dimensioned and arranged to be slid through a portion of the closed loop stitch that protrudes from the top opening of the first hole in the clavicle after the first fastener is set beneath the coracoid, and the loop stitch is pulled upward through the passage defined between the top opening of the first hole and the bottom opening of the second hole.

2. A fastener system according to claim 1, including a first suture arranged to pass through an apex of the loop stitch for pulling the loop stitch upward through said passage.

3. A fastener system according to claim 1, including a second suture arranged to pass through the outer pair of openings in the body of the first fastener, wherein tails of the second suture are dimensioned to extend through said passage and pass through the outer pair of openings in the body of the second fastener, when the first fastener is set beneath coracoid and the second fastener is centered under the protruding portion of the loop stitch, and the tails of the suture are tied to lock the protruding portion of the loop stitch in place with respect to the second fastener.

4. A fastener system according to claim 1, including a third suture arranged to pass through the outer pair of openings in the body of the first fastener, wherein tails of the third suture are dimensioned to extend through the hole in the coracoid and are tied at a third hole that is bored in the clavicle lateral to the top opening of the first hole.

5. A surgical fastener system for treatment of acromioclavicular (AC) joint dislocations, comprising:

a first fastener including an elongate fastener body having an outer pair of openings formed in the vicinity of opposite ends of the body, and an inner pair of openings formed between the outer pair of openings;

a second fastener including an elongate fastener body having at least an inner pair of openings; and

an endless or closed loop stitch a first portion of which passes through the inner pair of openings in the first fastener body and a second portion of which passes through the inner pair of openings in the second fastener body, wherein the loop stitch has a length that corresponds to a measured depth of a passage defined between a top opening of a first hole bored through a patient'"'"'s clavicle, to a bottom opening of a second hole bored through the patient'"'"'s coracoid in axial alignment with the first hole.

6. A fastener system according to claim 5, including a first suture arranged to pass through one opening of the outer pair of openings in the body of the first fastener, and a second suture arranged to pass through the other opening of said outer pair, wherein the first and the second sutures are dimensioned to extend through said passage and out of the top opening of the first hole in the clavicle, for pulling the first fastener upward through the passage after the second fastener is set beneath the coracoid.

7. A fastener system according to claim 5, including a third suture arranged to pass through the outer pair of openings in the body of the second fastener, wherein tails of the third suture are dimensioned to extend through the hole in the coracoid and are tied at a third hole that is bored in the clavicle lateral to the top opening of the first hole.
