Adjustable prosthetic interfaces and related systems and methods

1. A method of manufacturing an adjustable prosthetic socket, the method comprising:

advancing liquid resin about at least a portion of a guide;

permitting the liquid resin to set so as to form at least a portion of a wall structure of a prosthetic socket;

cutting through the wall structure of the prosthetic socket so as to separate a panel from a receptacle portion of the socket;

coupling a tensioning line to both the separated panel and the receptacle portion of the socket;

attaching a tightening mechanism to the socket; and

connecting the tensioning line to the tightening mechanism, wherein the tightening mechanism is configured to adjust tension in the tensioning line so as to move the panel relative to the receptacle portion of the socket,

wherein the guide is integral to the wall structure,

wherein cutting through the wall structure of the prosthetic socket comprises cutting through the guide.

2. The method of claim 1 , wherein coupling the tensioning line to both the separated panel and the receptacle portion of the socket comprises advancing the tensioning line through both a portion of the guide that is within the panel and a portion of the guide that is within the wall structure.

3. The method of claim 1 , further comprising attaching the guide to an outer surface of the panel, wherein coupling the tensioning line to the separated panel comprises advancing the tensioning line through the guide.

4. The method of claim 1 , further comprising:

forming at least a portion of the wall structure by advancing liquid resin about at least a portion of a rigid template; and

removing the template from the wall structure so as to provide a void within the wall structure,

wherein attaching the tightening mechanism to the prosthetic socket comprises inserting at least a portion of the tightening mechanism into the void.

5. The method of claim 4 , wherein the tightening mechanism comprises a base that defines an outermost perimeter and the rigid template defines an outermost perimeter that is the same size as or larger than the outermost perimeter of the base.

6. The method of claim 4 , wherein the template comprises a protrusion that forms a recess in the wall structure, and wherein attaching the tightening mechanism to the prosthetic socket comprises inserting a tab defined by the tightening mechanism into the recess.

7. The method of claim 1 , wherein coupling the tensioning line to the separated panel comprises advancing a first portion of the tensioning line through a first portion of a guide in a first direction and advancing a second portion of the tensioning line through a second portion of a guide in a second direction that is substantially opposite to the first direction.

8. The method of claim 1 , further comprising:

cutting through the wall structure of the prosthetic socket so as to separate a second panel from the receptacle portion of the socket;

coupling a second tensioning line to both the separated second panel and the receptacle portion of the socket;

attaching a second tightening mechanism to the prosthetic socket; and

connecting the second tensioning line to the second tightening mechanism, wherein the second tightening mechanism is configured to adjust tension in the second tensioning line so as to move the second panel relative to the receptacle portion of the socket.

9. The method of claim 1 , further comprising:

cutting through the wall structure of the prosthetic socket so as to separate an additional panel from the receptacle portion of the socket; and

coupling the tensioning line to the separated additional panel,

wherein the tightening mechanism is configured to adjust tension in the tensioning line so as to move both separated panels relative to the receptacle portion of the socket.

10. The method of claim 1 , wherein the tightening mechanism is attached to the receptacle portion of the socket.

11. The method of claim 1 , wherein the tightening mechanism is attached to the panel, and wherein attaching the tightening mechanism to the prosthetic socket takes place before cutting through the wall structure.

12. The method of claim 1 , further comprising attaching a pad to an interior surface of the socket such that the panel is attached to the pad and such that the panel and the pad together define a thickness that is greater than a thickness defined by portions of the socket that are adjacent to the panel.
