Abstract
A tendon repair implant and related surgical instruments are disclosed. The tendon repair implant has an elongated substrate with a convex side and a concave side with a plurality of spikes protruding from the concave side at an angle that optimally retains a tendon to the bone that the tendon repair implant is subsequently attached to. A surgical retainer for the tendon repair implant is also provided that releasably retains the tendon repair implant during surgery and implantation. A drill guide instrument for the tendon repair implant is also provided that allows the surgeon to precisely place fastening holes in the bone prior to implantation of the tendon repair implant.

A tendon repair system, comprising:
- a tendon repair implant comprising:
- an elongated substrate comprising a convex top side, a concave bottom side, a front side, a rear side, a first end portion and a second end portion;
- and
- a plurality of spikes protruding from the concave bottom side,
- wherein the first end portion comprises a first attachment portion configured for fastening the implant to a mammalian bone with the concave bottom side of the substrate facing the mammalian bone, the first attachment portion comprising a first fastening aperture extending through the first end portion of the substrate between the convex top side and the concave bottom side,
- wherein the second end portion comprises a second attachment portion configured for fastening the implant to the mammalian bone with the concave bottom side of the substrate facing the mammalian bone, the second attachment portion comprising a second fastening aperture extending through the second end portion of the substrate between the convex top side and the concave bottom side, and
- wherein the plurality of spikes is positioned between the first and second attachment portions, and the spikes of the plurality of spikes protrude from the concave bottom side of the substrate at an angle with respect to a line perpendicular to the concave bottom side of the substrate;
- and
- an implant retainer instrument configured to removably retain the tendon repair implant, comprising:
- an elongated implant backer portion comprising a top side, a concave bottom side, a front side, a rear side, a first end portion and a second end portion, wherein the concave bottom side of the implant backer portion is configured to engage with the convex top side of the substrate of the tendon repair implant;
- a plurality of flexible retention prongs extending from peripheral portions of the concave bottom side of the implant backer portion configured to engage peripheral portions of the substrate of the tendon repair implant when the convex top side of the is engaged with the concave bottom side of the implant backer portion to releasably retain the tendon repair implant on the elongated implant backer portion;
- and
- an elongated handle extending from the top side of the implant backer portion,
- wherein the first end portion of the implant backer portion comprises a first cutout and the second end portion of the implant backer portion comprises a second cutout, wherein the first and second cutouts are configured to align with the first and second fastening apertures, respectively, when the tendon repair implant is releasably retained on the elongated implant backer portion to provide access to the first and second fastening apertures for the insertion of first and second surgical screws, respectively, therein.
