Abstract
A system and method for attaching soft tissue to a prosthetic implant can include a prosthetic component that defines a soft tissue attachment region having an attachment surface thereon. A first construct can be formed of porous metal and be removably coupled to the attachment surface. A second construct can be positioned outboard of the soft tissue. A fastener can be engaged to the second construct capturing the soft tissue against the first construct. The fastener can be coupled on a distal end to the first prosthetic component.
Claims21
A femoral prosthesis system having a tissue attachment portion, comprising:
- a proximal femoral prosthesis having a stem portion and a neck portion and configured to replace at least a portion of a proximal portion of a femur that is medial of a greater trochanter of the femur;
- an attachment assembly separate from the proximal femoral prosthesis;
- a first porous metal pad that is generally planar and fixed directly to an inferior surface of a portion of the proximal femoral prosthesis that is on a medial portion of the proximal femoral prosthesis and is extending substantially transverse to a long axis of the femur and where the first porous metal pad is operable to allow boney ingrowth directly into the first porous metal pad directly from a resected proximal surface of the femur;
- and
- a first fastener operable to interconnect the attachment assembly and the proximal femoral prosthesis.
A femoral prosthesis system having a tissue attachment portion, comprising:
- a proximal femoral prosthesis having a stem portion and a neck portion and configured to replace at least a portion of a proximal portion of a femur that is medial of a greater trochanter of the femur;
- an attachment assembly separate from the proximal femoral prosthesis, the attachment assembly having a first surface and a second surface with an aperture defined through the first surface and the second surface, the attachment assembly further having a first terminal end tip and a second terminal end tip, the second surface operable to selectively and removably engage the greater trochanter of the femur, and wherein the second surface includes a first porous metal pad that extends less than an entire distance between the first terminal end tip and the second terminal end tip of the attachment assembly and is operable to allow boney ingrowth directly into the first porous metal pad;
- and
- a fastener separate from the proximal femoral prosthesis and the attachment assembly operable to interconnect the attachment assembly and the proximal femoral prosthesis;
- wherein the first porous metal pad of the attachment assembly is operable to directly contact the greater trochanter to allow boney ingrowth directly into the first porous metal pad.
A femoral prosthesis system having a tissue attachment portion, comprising:
- a proximal femoral prosthesis configured to replace at least a proximal portion of a femur of an anatomy;
- an attachment assembly separate from the proximal femoral prosthesis having a first surface and a second surface and an aperture extending between and through the first surface and the second surface, the attachment assembly including a porous metal pad operable to contact a tissue portion wherein the attachment assembly has an arcuate shape terminating in a first end tip and a second end tip wherein the first end tip and the second end tip are both operable to engage the proximal portion of the femur;
- a first fastener operable to hold the attachment assembly and the proximal femoral prosthesis relative to each other and the tissue portion and to capture the tissue portion relative to the proximal portion of the femur;
- and
- a second fastener;
- wherein the first fastener passes through a first bore formed from a lateral side to a medial side of the proximal femoral prosthesis and a second bore formed in the attachment assembly to threadably engage the second fastener on the medial side of the proximal femoral prosthesis in a coupled position.
