Abstract
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. At least one spine extends upwardly from the distal base toward the proximal end. The at least one spine defines at least part of a circumference of the socket about the axis. A proximal support is located at or near the proximal end of the socket and extends from the at least one spine. The proximal support is arranged to distribute pressure from the at least one spine over a portion of the residual limb. A tensioning system is operatively connected to the at least one spine and arranged to selectively adjust the circumference of the socket.

An adjustable prosthetic socket having proximal and distal ends and an axis extending between the proximal and distal ends, comprising:
- a distal base adapted to support a distal portion of a residual limb and located at the distal end of the socket, the distal base including:
- a first base component defining a recess inside a lower part of the first base component;
- and
- a second base component including a horizontally projecting part slidably received within the recess, wherein the recess defines a side opening and walls extending over and under the horizontally projecting part of the second base component, wherein the first base component defines a first raised side and the second base component defines a second raised side forming a cup shaped to fit the distal portion of the residual limb;
- first and second spines extending upwardly from the distal base toward the proximal end and defining at least part of a circumference of the socket about the axis, the first spine being attached to the first base component and the second spine being attached to the second base component, wherein the second spine pivots toward and away from the first spine about a hinge connection between the second spine and the second base component, wherein the second base component is lockable at a plurality of different radial positions within the recess to selectively adjust the circumference of the socket;
- a proximal support attached to the second spine and extending from the second spine, the proximal support arranged to distribute pressure from the second spine over a portion of the residual limb;
- and
- a tensioning system operatively connected to the spines and arranged to selectively adjust the circumference of the socket.

- a plurality of lateral flaps extending from sides of the first and second spines, the lateral flaps defining at least part of the circumference of the socket about the axis and having a dimension which allows for some overlap between anterior ones of the lateral flaps and posterior ones of the lateral flaps when the socket is worn on the residual limb;
- and
- a tensioning system operatively connected to the first and second spines and arranged to selectively adjust the circumference of the socket.
