SOFT TISSUE ATTACHMENT DEVICE

摘要

Methods and devices are disclosed for the attachment of a soft tissue structure (e.g., tendon or ligament) to bone or a prosthetic implant. In one form, the device includes a clamp having a convex tissue engaging surface. A fastener compresses the soft tissue between the tissue engaging surface and the bone or the prosthetic implant. In another form, the device includes a second clamp comprising a porous metallic material. The second clamp has a first surface, a concave tissue engaging surface opposite the first surface, and a throughhole for a fastener. The second clamp is placed adjacent the bone, the soft tissue is placed adjacent the second clamp, and the first clamp is placed adjacent the soft tissue. The soft tissue is compressed between the convex tissue engaging surface of the first clamp and the concave tissue engaging surface of the second clamp using the fastener.

主权项

1. A device for attaching soft tissue to a single bone, or to first and second bones, or to a single prosthetic implant, or to first and second prosthetic implants, the device comprising:
a first attachment device including a first clamp comprising a porous metallic material, the first clamp including a first surface, a convex tissue engaging surface opposite the first surface, and a throughhole extending from the first surface to the convex tissue engaging surface; a fastener dimensioned for placement in the throughhole of the first clamp, the fastener being dimensioned to engage a surface of the first clamp, the soft tissue and the single bone, the first bone, the single prosthetic implant, or the first prosthetic implant such that the soft tissue is compressed between the tissue engaging surface and the single bone, the first bone, the single prosthetic implant, or the first prosthetic implant; and a second attachment device including a first part comprising a porous metallic material and a mating second part comprising a porous metallic material, wherein the soft tissue is compressed between the first part and the second part.
