Abstract

Provided herein are devices and methods for connecting a transcutaneous external prosthetic device to a bone, such as a bone of an amputee. The device is a two-piece transcutaneous implant device to provide reversible connection for ease of implantation, reliability, and relatively easy access for removal, while maximizing tissue ingrowth to reduce risk of infection and attendant adverse outcomes. The devices provided herein comprise a prosthetic interface and a bone anchor. A through-hole that traverses a longitudinal length of the prosthetic interface and at least a longitudinal portion of the bone anchor receives a fastener to reversibly connect the prosthetic interface to the bone anchor implanted in bone. A connector may connect to a failsafe element which, in turn, connects to an external prosthetic device.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims benefit to U.S. Provisional Patent Application Nos. 61 / 698,866, filed Sep. 10, 2012 and 61 / 820,264 filed May 7, 2013, each of which are incorporated by reference to the extent not inconsistent herewith.BACKGROUND OF THE INVENTION

[0002] Provided herein are devices and related methods for mechanically connecting an external prosthetic device to a user's skeleton via a transcutaneous implant.

[0003] Currently, amputees are most commonly fit with a socket interface prosthesis, with the socket contoured to fit the individual's residual limb. In this manner, the socket interface transmits forces from the appendicular skeleton through the soft tissues to the prosthesis. There are a number of significant disadvantages with such a configuration. First, skin breakdown is common as the soft-tissue / socket interface may create excessive pressure areas on the skin. The transmission of forces from the skeleton through the soft tissu...
