An adjustable prosthesis system for a residual limb includes: an adjustable outer shell having a bottom, an adjustable inner volume, and an adjustable inner shape; at least one closure component attached to the outer shell and adapted to adjust the width of the inner volume and/or inner shape; an inner liner adapted to receive the residual limb and to be inserted in the inner volume; and an adjustable connector having a proximal end adjustably connected to a distal end of the outer shell and adapted to provide concurrently for a plurality of directional adjustments and/or angular adjustments of a position of the distal end of the outer shell relative to the proximal end of the connector, a distal end of the connector adapted to connect to a prosthetic device, wherein adjustments of the width(s) and the connector provide for a custom-like fit of the prosthesis on the residual limb.

A liner for an orthopedic or prosthetic device includes a core formed from a porous and compressible material, a first layer secured to the first side of the core and forming a first surface to the liner, and a second layer secured to the second side of the core and forming a second surface to the liner. The first and second layers may comprise different properties from one another and be formed from different materials including fabrics and polymeric materials. A polymeric film may be secured to the core or one of the layers to define at least part of a surface of the liner.

An adjustable prosthetic socket includes proximal and distal ends and an axis extending between the proximal and distal ends. A distal base is adapted to support a distal portion of a residual limb and is located at the distal end of the socket. First and second spines extend upward from the distal base that define at least part of a circumference of the socket about the axis. A proximal support is connected to the second spine and arranged to distribute pressure from the second spine over a portion of the residual limb. A tensioning system is operatively connected to the first and second spines and arranged to selectively adjust the circumference of the socket. The tensioning system includes a dial tensioner connected to the first spine.

A disarticulated compression socket configured to secure a residual limb. The disarticulated compression socket may include a rigid socket frame having one or more compression apertures each having one or more disarticulated compression inserts. Each disarticulated compression insert may be coupled with and/or responsive to a compression band configured to compress the disarticulated compression inserts and thereby secure a residual limb within the rigid socket frame.

A prosthetic socket, comprising a base for distal connection means for attaching a prosthesis component to the prosthetic socket and comprising at least one side wall, which extends from the base in the proximal direction and at least partially extends around a stump to be held in the prosthetic socket, and at least one support for fastening the side wall to the base being arranged on the base.

A method of placing a prosthetic system over a residual limb, said method comprising the steps of: providing the prosthetic system; and placing an outer shell of the prosthetic system on the residual limb having an above-knee amputation, the outer shell at least partially surrounds the residual limb, an outer side and an inner side of the outer shell on opposite sides of the residual limb, an upper edge of the outer side above a greater trochanter, the inner side below a lowest edge of an ischium without being directly below the lowest edge of the ischium.

A method of providing a modular prosthetic socket for a residual limb of a patient may involve receiving digital data defining a three-dimensional digital profile of the residual limb and selecting prosthetic socket components from component-specific inventories, based at least in part on the digital profile. The selected prosthetic socket components may include: multiple longitudinal struts; one or more proximal brim members for attachment to the longitudinal struts; and a distal socket base to which the longitudinal struts attach at or near their distal ends. The method may further involve providing the selected prosthetic components to an operator for assembling into the modular prosthetic socket. The prosthetic socket, when assembled, defines an internal space substantially complementary to the profile of the residual limb.

A prosthetic socket system comprising a prosthetic socket and a liner, said prosthetic socket having a distal end region, at least one socket wall extending therefrom in proximal direction, and connection means for securing a prosthetic component. The socket wall, when in the applied state, at least partially enclose a stump that is received in the prosthetic socket The liner includes a proximal entry opening and a lateral wall which extends in the distal direction, at least partially surrounds a stump when in the applied state and is arranged between the stump and the prosthetic socket when in the applied state. A coupling device is arranged between the liner and the prosthetic socket in the distal end region, and, on the outer side of the lateral wall of the liner and on the inner side of the socket wall, resistance regions are arranged or formed which interact with one another and which counteract a movement extracting said liner out of the prosthetic socket, in the proximal direction.

A flexible prosthetic liner having a proximal access opening for a stump of a limb and a distal end region as well as a flexible tension member which is arranged in the distal 5 end region on the prosthetic liner. The tension member is detachably fastened to the prosthetic liner by means of a closure system that can be actuated without a tool. A prosthetic shaft system may be formed by such a prosthetic liner and a prosthetic shaft.
