Method of making an anatomical socket
View Patent ↗An anatomical socket is fashioned to attach to an amputated limb, which can be a median between the amputated limb and the prosthesis device. The method produces, based on specific measurements of a user, an anatomical socket that provides the user with cosmesis, a greater range of motion, a better gait and comfort. The socket has a low upper rim to allow for the greatest mobility of the hip joint. The socket is produced of a durable and smooth plastic. The socket fits in a secure, yet removable manner to the prosthesis. The method disclosed herein takes precise measurements of the wearer's limb to provide for optimal fitting and comfort.
1. A method for making an anatomical socket for a user's limb, comprising:
fashioning an anterior end that angles down from the user's limb's medial end, and then angles sharply upward toward the user's limb's distal end;
placing a lateral end adjacent to said anterior end, said lateral end higher than said anterior end, said lateral end curving around the hip of the user's limb;
placing a medial end adjacent to said anterior end, said medial end having a wall fashioned to an anterior position over a medial aspect of the ischial ramus of the user from behind adductor muscles to a posterior aspect of the ischial ramus such that said wall is parallel to the ischial ramus and such that there is no weight bearing over the ischial ramus and ischial tuberosity; and
placing a posterior end adjacent to said lateral end and said medial end, said posterior end having a lower height than said anterior end, said posterior end above the user's thigh;
wherein said anterior end and said medial end exert a first force on the user's limb, while said posterior end and said medial end exert a second force on the user's limb, such that said lateral end and said medial end have a resultant force there between,
wherein the recited relationships of the anterior end, lateral end, medial end, and posterior end to the user's anatomy occur when the user's limb is oriented in a standing position.
2. The method of claim 1 , wherein said posterior end is fashioned to fit the user's limb no higher than the user's gluteal fold.
3. The method of claim 1 , wherein said anterior end is made to have a top curvature to fit the medial aspect of the user's ischial ramus.
4. The method of claim 1 , wherein said anterior end is made to have a ledge and wall to receive the user's ischial ramus there between.
5. A method for making an anatomical socket for a user's limb, comprising:
fashioning an anterior end that angles down from the user's limb's medial end, and then angles sharply upward toward the user's limb's distal end;
placing a lateral end adjacent to said anterior end, said lateral end higher than said anterior end, said lateral end curving around the hip of the user's limb;
placing a medial end adjacent to said anterior end, said medial end having a wall fashioned to an anterior position over a medial aspect of the ischial ramus of the user from behind adductor muscles a posterior aspect of the ischial ramus such that said wall is parallel to the ischial ramus and such that there is no weight bearing over the ischial ramus and ischial tuberosity; and
placing a posterior end adjacent to said lateral end and said medial end, said posterior end having a lower height than said anterior end, said posterior end above the user's thigh;
wherein at least said anterior end; said lateral end, said medial end, or said posterior end has a top trim curvature,
wherein the recited relationships of the anterior end, lateral end, medial end, and posterior end to the user's anatomy occur when the user's limb is oriented in a standing position.
6. The method of claim 5 , wherein said posterior end is fashioned to fit the user's limb no higher than the user's gluteal fold.
