## Abstract

Surgical implant systems, methods, and components are described herein. More particularly, the disclosure relates to joint arthroplasty systems, methods, and components. Particular embodiments described herein can be used to modify the subtalar joint (e.g., posterior facet of the subtalar joint), calcaneocuboid, talonavicular, and any other suitable joint. An exemplary implant system comprises a first implant component, a second implant component, and an insert.

## Claims

### Claim at position 1

1-20. (canceled)

### Claim 21

A system for use in a joint arthroplasty, the system comprising:
a first implant component having a first implant proximal end, a first implant distal end, and a first implant body defining a first implant surface, a concave first articulating surface opposably facing the first implant surface, and a plurality of first implant projections extending outward and away from the first implant surface from a first implant projection first end to a first implant projection second end for each of said plurality of first implant projections, wherein said plurality of first implant projections are adapted to attach said first implant component to a first implant site;
a second implant component having a second implant proximal end, a second implant distal end, and a second implant body defining a second implant surface, a recess extending into the second implant body from a side opposably facing the second implant surface to a recess base, and a plurality of second implant bores, each second implant bore adapted to allow a fastener there through, said fastener adapted to attach said second implant component to a second implant site; and
an insert adapted to be releasably attached to the second implant component and having an insert articulating surface that is convex and adapted to articulate with the first articulating surface,
wherein said system is adapted for implanting at said first implant site and said second implant site within a joint.

### Claim 22 (depends on 21)

The system of claim 21, wherein the recess extends from the second implant proximal end toward the second implant distal end and has a recess first portion extending from the recess base and away from the second implant surface and a recess second portion extending from the recess first portion and configured to provide a slideable engagement between said second implant component and said insert.

### Claim 23 (depends on 21)

The system of claim 21, wherein said first implant surface is porous.

### Claim 24 (depends on 21)

The system of claim 21, wherein each of said plurality of first implant projections is elongated.

### Claim 25 (depends on 21)

The system of claim 21, wherein each of said plurality of first implant projections comprises a serrated first implant projection second end providing a structural configuration for increasing the amount of attachment between said first implant component and said first implant site.

### Claim 26 (depends on 24)

The system of claim 24, wherein each of said plurality of first implant projections have a circular cross section along its length from the first implant projection first end to the first implant projection second end.

### Claim 27 (depends on 25)

The system of claim 25, wherein each of said plurality of first implant projections defines a first implant projection second end that is pointed.

### Claim 28 (depends on 21)

The system of claim 21, wherein said joint is within a foot.

### Claim 29 (depends on 21)

The system of claim 21, wherein said joint is selected from the group consisting of a subtalar joint, a calcaneocuboid joint, and a talonavicular joint and said first implant surface and said second implant surface are adapted for implanting within said joint.

### Claim 30 (depends on 21)

The system of claim 21, wherein the first implant component is adapted to be attached to the talus; and wherein the second implant component is adapted to be attached to the calcaneus.

### Claim 31 (depends on 21)

The system of claim 21, wherein said first implant component further comprises at least one first implant protuberance extending outward and away from the first implant surface and a passageway extending from a first opening defined on a first end of said at least one first implant protuberance to a second opening defined on a second end of said at least one first implant protuberance.

### Claim 32 (depends on 31)

The system of claim 31, the system further comprising a first implant fastener disposed through the passageway defined by the first implant component and a second implant fastener disposed through one of said plurality of second implant bores.

### Claim 33 (depends on 21)

The system of claim 21, the system further comprising a second implant fastener disposed through one of said plurality of second implant bores, wherein said second implant fastener is adapted to attach said second implant component to a second implant site.

### Claim 34 (depends on 21)

A method of using the system of claim 21, comprising installing said first implant component onto a first bone of said first implant site and installing said second implant component to a second bone of said second implant site thereby implanting said system within said joint.

### Claim 35

A system for use in a joint arthroplasty, the system comprising:
a first implant component having a first implant proximal end, a first implant distal end, and a first implant body defining a first implant surface, a concave first articulating surface opposably facing the first implant surface, and a plurality of first implant projections extending outward and away from the first implant surface from a first implant projection first end to a first implant projection second end for each of said plurality of first implant projections, wherein said plurality of first implant projections are adapted to attach said first implant component to a first implant site;
a second implant component having a second implant proximal end, a second implant distal end, and a second implant body defining a second implant surface, a recess extending into the second implant body from a side opposably facing the second implant surface to a recess base, and a plurality of second implant projections extending outward and away from the second implant surface from a second implant projection first end to a second implant projection second end for each of said plurality of second implant projections, wherein said plurality of second implant projections are adapted to attach said second implant component to a second implant site; and
an insert adapted to be releasably attached to the second implant component and having an insert articulating surface that is convex and adapted to articulate with the first articulating surface,
wherein said system is adapted for implanting at said first implant site and said second implant site within a joint.

### Claim 36 (depends on 35)

The system of claim 35, wherein the recess extends from the second implant proximal end toward the second implant distal end and has a recess first portion extending from the recess base and away from the second implant surface and a recess second portion extending from the recess first portion and configured to provide a slideable engagement between said second implant component and said insert.

### Claim 37 (depends on 35)
