The present disclosure is directed to prosthetic limb sockets that couple prosthetic limbs to residual limbs. The sockets include a conical cup sized to engage and couple to the residual limb, and a base to secure the socket to the prosthetic limb. The sockets are direct heat-formable onto the residual limb, such that they can be heated and formed as they are secured to the residual limb.

A failsafe for a transdermal apparatus for a prosthetic appendage can include a first plate, a second plate, and a breakaway connector. The first plate can have a central axis, a proximal portion, and a distal end. The distal end can be opposite the proximal portion, and the distal end can be securable with a prosthetic external to skin and can be configured to simulate an appendage of a patient. The second plate can be aligned with the central axis and can include a proximal end and a distal portion. The proximal end can be securable to a transdermal implant, and can extend proximally from the second plate. The distal portion can be opposite the proximal end, and the distal portion can be configured to interface with the proximal portion of the first plate. The breakaway connector can be couplable within the second plate and the first plate.

A transdermal intraosseous device for coupling a bone stump to an external prosthetic device includes a bone fixator, an external connector and a plurality of modular interface components. The bone fixator includes a proximal portion configured for anchoring into the bone stump of the patient and a distal portion including a base collar configured for subcutaneous implantation. The external connector has a distal portion for coupling to the external prosthetic device and a proximal portion for coupling to the distal portion of the bone fixator. Each interface component can be removably coupled to the base collar and has different size and shape to provide a surgeon-selected transition between the prosthetic device and the patient's skin.

A method and an osseointegrated prosthesis system having an osseointegrated prosthesis member are provided having a monitoring system operably coupled to the osseointegrated prosthesis member configured to quantitatively assess the osseointegration of the osseointegrated prosthesis member, a wave-generating element coupled to the osseointegrated prosthesis member and configured to output guided waves along the osseointegrated prosthesis member interrogating an interface between bone and the osseointegrated prosthesis member, and a sensing system configured to sense a condition of the interface between bone and the prosthesis.

In the case of known prosthesis systems and socket supplies, the transmission of force is a critical issue. The inventive prosthesis system shall improve known prosthesis systems. According to the invention, a prosthesis system for human limbs is provided, which comprises an implant (101) having at least two joint parts which are movable relative to each other, wherein the first joint part (110) can be connected to a bone part (131, 132) and the second joint part (120) comprises a subcutaneously arrangeable end part (124) on the side being remote from the joint. The invention further relates to a prosthesis system comprising a subcutaneous implant and a socket (170).
