Benefits of technology
"The present invention is a suture attachment clip for repairing soft tissue to bone. The clip has a head that allows for the passage of a suture and can be attached to a bone plate during manufacture or surgery. The clip can be designed to fit existing bone plates or can be simultaneously designed and manufactured. The clip can be attached to the bone plate by snapping, screwing, or inserting a free end of the clip through a pair of receiving orifices in the bone plate. The multi-clip assembly can also be attached to the bone with standard bone screws or fasteners through a plurality of eyelets positioned on the assembly. The technical effects of the invention include providing multiple options for soft tissue repair to bone and facilitating the attachment of soft tissue to bone during surgery."
Problems solved by technology
Existing plate systems utilized in orthopaedic surgical procedures, such as fracture fixation or reconstruction procedures, provide limited options for incorporating additional soft tissue anchoring into the plate.
Often, the small amount and small size of the orifices on the plate are not sufficient to repair significant soft tissue components.
In addition, it is often very difficult to pass a needle, curved or straight, through these orifices once the plate has been screwed to the bone.
Accordingly, existing bone plates provide limited options for soft tissue reattachment.
While the clinical success of bone anchors for the reattachment of tendon or ligament in musculoskeletal reconstruction is well documented, most existing bone anchors fail where the bone is very soft—as, or example, in severe osteopenia—or where the bone is very fragmented—as, for example, in fractures with severe bone fragmentation or comminution.
In these instances, traditional bone anchors are inadequate for the reattachment of tendons and ligaments to bone.

Embodiment Construction
[0024]As shown in FIG. 1, in one embodiment of the present invention, the suture attachment clip 1 comprises a head 2 suitably shaped to allow the passage of a suture during the attachment of soft tissue to bone. In this embodiment, the head 2 preferably has a first and second lobe 3 and 4. In a preferred embodiment of the present invention, the first and second lobes 3 and 4 are symmetrical with respect to one another. In a preferred embodiment of the present invention, first and second lobes 3 and 4 are continuous with first and second prongs 5 and 6 wherein first prong 5 has a first outwardly protruding terminal end 7 and second prong 6 has a second outwardly protruding terminal end 8. Preferably, the head 2, prongs 5 and 6, and terminal ends 7 and 8 form an inverse-omega shape when clip 1 is viewed from the top perspective depicted in FIG. 1.
[0025]As shown in FIG. 2, a plurality of individual clips 1 can attach to a bone plate 9 by snapping prongs 5 and 6 of each respective clip...

A suture attachment clip and method for assisting in the attachment or re-attachment of soft tissue to bone. The clip generally comprises a head having a shape suitable for allowing the passage of a suture during attachment of soft tissue to bone. One or more clips can be secured to a bone plate through a variety of means, including a snap configuration, a screw configuration, and a bendable prong configuration. The clip can also be continuous with an adjacent clip, thus forming a multi-clip assembly that can either be secured to a bone plate or secured directly to a bone without a bone plate.
Description
CROSS REFERENCES TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 61 / 045,860, filed on Apr. 17, 2008, the complete disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to orthopedic devices used in the reattachment of soft tissue to bone in acute injuries or reconstructive procedures.BACKGROUND OF THE INVENTION[0003]The present device and method provides a significant improvement for soft tissue attachment or reattachment to bone in acute injury or in reconstructive procedures. The various embodiments of the present invention can be used in conjunction with bone plates or by itself.[0004]Musculoskeletal injuries constitute combinations of bone and soft tissue injury. As such, bone fractures frequently have associated tendon or ligament tears. Fractures around joints—know in the art as periarticular fractures—are classic examples of...
