Benefits of technology

The invention describes an abutment for an anchor used in dental implants. The abutment has recesses where tools can be inserted and used to attach the anchor to the bone. The recesses have passages where sutures can be placed. The abutment is designed to securely hold the tool and reduce stress on the anchor body during use. The threads on the abutment have a small outer diameter, and the sutures used are of a certain gauge. These features improve the stability and efficiency of the dental implant procedure.

Problems solved by technology

A PASTA (Partial Articular Surface Tendon Avulsion) lesion in a rotator cuff of a shoulder can be particularly difficult to repair.
Preservation of the existing attachment is thus lost and the entire tendon must be reattached.
This creates significant trauma to the tendon.

Embodiment Construction

[0024]FIG. 1 depicts a suture anchor 10 according to the present invention. It comprises an elongated body 12 having a pointed distal tip 14 and a proximal end 16. An axial passageway 18 extends into the body 12 from the proximal end 16. The passageway 18 is open along its sides 20. A thread 22 encircles the body 12. A suture bridge 24 spans the passageway 18 laterally at a distal portion 26 thereof.

[0025]Turning also now to FIGS. 2 and 3, an inserter 28 fits into the passageway 18. A length of suture 30 passes around the suture bridge 24 and is received within longitudinal grooves 32 on the inserter 28. As best seen in FIG. 3, the cross-sectional shape of the passageway 18 at the proximal end 16 is essentially a hexagon 34 with a pair of suture passages 36 on opposite corners thereof. The suture passages 36 lead to either side of the suture bridge 24. The inserter 28 has a complimentary shape to fit within the hexagon 34 with its grooves 32 in alignment with the suture passages 36 ...

Abstract

A suture anchor is disclosed which has an elongated body having a distal end, a proximal end and an exterior surface. An axially oriented bore extends into the body from the proximal end and a proximal portion of the bore has a plurality of abutment surfaces for engaging a tool. The bore includes one or more axially oriented suture passages leading to a suture attachment within the bore. A length of suture extends into the at least one suture passage from the body proximal end and extends to the suture attachment. A screw thread spirals about a portion of the exterior surface of the body adjacent the at least one suture passage. Between the bore and the exterior surface of the body the body has a wall thickness and wherein the suture passage comprises the area where the wall thickness goes to zero.

Description

BACKGROUND[0001]The present application relates to systems and methods for performing a repair of a partial thickness rotator cuff tear.[0002]A PASTA (Partial Articular Surface Tendon Avulsion) lesion in a rotator cuff of a shoulder can be particularly difficult to repair. The rotator cuff comprises a group of muscles which surround the shoulder and tendons which attach those muscles to the humeral head. The tendons have a footprint where they attach to the humeral head and in a PASTA lesion a portion of the tendon's footprint becomes detached from the humeral head. Such lesions are most commonly found on the supraspinatus tendon. One option for treatment is completion of the tear and repair using standard techniques for a full thickness tear. Preservation of the existing attachment is thus lost and the entire tendon must be reattached. A further option is to create an incision through the tendon and place a standard suture anchor therethrough. This creates significant trauma to the...
