The invention is a method of designing and manufacturing a 3D printed prosthetic socket or a standard prosthetic socket with a 3D printed distal end, comprising a step of obtaining physical data about a patient with a residual limb and a step of creating a structural design of the 3D printed prosthetic socket or standard prosthetic socket with the 3D printed distal end. The step of creating the structural design of the 3D printed prosthetic socket (3) or standard prosthetic socket with the 3D printed distal end comprises a step of determining the bulk density of the structure of the prosthetic socket between a shaped area for positioning a linking part of the liner and a distal planar area for mounting a linking adapter of the socket directly proportional to at least one of the data from a set including at least weight, patient's degree of activity, length of the residual limb, length of the prosthesis, size of the prosthetic foot, and angle between the axis of the limb and the axis of the prosthesis.

A method for designing a two-part joint prosthesis (830) comprises: providing kinematic data of a subject's joint under load; and designing the joint prosthesis using the kinematic data, wherein the working surfaces of the two-part prosthesis comprise, consist essentially of or consist of cellular material. Advantageously, the method may not require any intra-operative adjustments to replace one or more of the components (831, 832), e.g. with a component of a different size. In particular, if components are made of biological tissues, such as a patient's own cells, it is advantageous to design and produce an implant that requires no adjustments intra-operatively as each implant may be manufactured specifically for each patient, and the time and costs of producing a range of sizes, most of which would not be required, would otherwise be prohibitive.

A method for manufacturing an orthopedic product for a body part of a patient is disclosed, the method comprising the following steps: a) providing body-part data containing information about an internal structure of the body part, b) detecting a current line of vision from which a user of the method sees the body part, c) displaying the body part data from the current line of vision by means of the display device so that the user sees the body part and the body part data superimposed, d) generating production data for the orthopedic device on the basis of the displayed data and e) providing an orthopedic product manufactured on the basis of the production data.

The invention is a 3D printed prosthetic socket for a residual limb consisting of a 3D printed shell. The 3D printed prosthetic socket comprises a distal end adapted for linking the interconnecting adapter of the socket and a proximal end with an opening adapted for inserting the limb. The 3D printed shell comprises a first housing of the socket comprising an inner wall, wherein between the first housing and the second housing, there is an air gap. The distal end adapted for linking an interconnecting adapter of the socket, the first housing and the second housing are made of single 3D printed part, wherein the first housing comprises an elastic region comprising set of shaped openings, and the first housing is connected with the second housing through a reinforcing structure composed of ribs.

A method for reducing motion of a skeletal structure in a limb towards a wall of an interface is described. The interface comprises a plurality of compression areas that are longitudinally-shaped and oriented longitudinally along the length of limb. The method comprises selecting, during a process of creating the interface, a compression level for the compression areas that compresses soft tissue against the skeletal structure. The method also comprises donning the interface over the limb to apply a plurality of compressive forces that is sufficient to aid in suspension of the interface on the limb and reduce motion of the skeletal structure toward a wall of the interface.

Prosthesis devices can include sockets having adjustable features. In one example, a socket includes one or more panels that can move outwardly or inwardly relative to a receptacle portion of the socket. The panels can be moved by tightening a tensioning line.

Disclosed herein are a method and system for producing a digital model of a customised device, comprising the steps of: importing a first digital file of a base part; importing a second digital file of a target shape; determining a warping interpolation function based on source point positions associated with the base part and target point positions associated with the target shape; and applying the warping interpolation function to the points of said base part to generate a model of said customised device.

A suspended sleeve assembly includes a suspension stand and a compression sleeve. An upper portion of the compression sleeve is attached onto the suspension stand, but a lower portion of the compression sleeve is unattached from the suspension stand. The suspended sleeve assembly can also include a support stand. The suspended sleeve assembly can be used to shape a prosthetic socket. The compression sleeve applies a circumferential pressure onto the prosthetic socket as the prosthetic socket is being inserted into the compression sleeve as a patient steps into the compression sleeve and applies at least a portion of body weight to the compression sleeve. The prosthetic socket can be heated and shaped by hand, so that it fits the residual limb of the patient. The suspended sleeve assembly can also be used to shape other prosthetic components, such as a negative plaster cast.

An expandable wall prosthetic socket configured with at least one retention ring in the socket wall and a telescoping element which interacts with the retention ring to allow the telescoping element to translate inwardly and outwardly through the socket wall, via the retention ring, such that the telescoping element is applying a force on the residual limb.

One embodiment provides for a fixed retention ring that is installed into the side of the socket wall. The retention ring is laminated into or bonded to the layered composite forming the socket wall. A telescoping element is installed through the retention and makes contact with, or is connected to, a force applicator plate. As the telescoping element translates inwardly, the telescoping element makes contact with (or pushes on) the force applicator such that the force applicator produces the load on the residual limb.

Additional embodiments provide for such features as a rotating retention ring, a two part panel with a retention ring and force applicator, and a force applicator designed into a prosthetic silicone liner.

Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.
