## Abstract

An assembly for mounting a prosthetic nail for a human or animal digit. The assembly includes at least one transdermal anchor with an interior portion and an exterior portion. The interior portion may be positioned within tissue of the digit, and the exterior portion may extend outside the tissue of the digit. In another aspect, an exterior base may be positioned on a nail bed of the digit, and the exterior base may be coupled to the exterior portion of the transdermal anchor. The base may include a mount for removably a prosthetic nail to the base.

## Claims

### Claim 1

A prosthetic nail mount assembly, comprising:
a transdermal anchor with an interior portion and an exterior portion, wherein the interior portion comprises tissue-engaging surfaces and is sized and configured to be positioned within tissue of a digit, and the exterior portion extends outside the tissue of the digit; and
an exterior base sized and configured to be directly positioned on a nail bed of the digit, wherein the exterior base includes couplers for engaging corresponding retention members at a distal end of the exterior portion of the transdermal anchor;
wherein the interior portion defines at least one through opening for capturing surrounding tissue of the digit, wherein the at least one through opening is defined by a ring.

### Claim 2 (depends on 1)

The prosthetic nail mount assembly of claim 1, wherein the interior portion further defines multiple through openings, and one of the through openings is tear-drop shaped.

### Claim 3 (depends on 1)

The prosthetic nail mount assembly of claim 1, wherein the interior portion includes an angled section angled outwardly to offset a remaining section of the interior portion away from a distal phalanx of the digit.

### Claim 4 (depends on 1)

The prosthetic nail mount assembly of claim 1, wherein the interior portion includes an arcuate extension at a proximal end of the interior portion for capturing surrounding tissue.

### Claim 5 (depends on 1)

The prosthetic nail mount assembly of claim 1, wherein the interior portion is free from direct bone contact in the digit.

### Claim 6 (depends on 1)

The prosthetic nail mount assembly of claim 1, wherein the transdermal anchor is made of a material that includes a rigid polymeric material.

### Claim 7 (depends on 1)

The prosthetic nail mount assembly of claim 1, wherein the transdermal anchor is made primarily of polyetheretherketone.

### Claim 8 (depends on 1)

The prosthetic nail mount assembly of claim 1, wherein the exterior base includes a mount for coupling the base to a prosthetic nail.

### Claim 9 (depends on 8)

The prosthetic nail mount assembly of claim 8, wherein the mount of the exterior base includes protrusions extending away from the base that are arranged to engage multiple couplers on the prosthetic nail.

### Claim 10 (depends on 9)

The prosthetic nail mount assembly of claim 9, wherein the protrusions include multiple portions at right angles to each other.
