What is ischial containment socket?
The term “ischial containment” is rather self-descriptive. A decreased emphasis on a narrow AP diameter between the adductor longus-Scarpa’s triangle and ischium for the maintenance of ischial-gluteal weight bearing. Total contact.
What is a transfemoral socket?
The transfemoral socket is the interface between the patient’s residual limb and the remaining prosthesis.
What is the most commonly used transfemoral socket design?
The most common approach to the design of the transfemoral socket was the carved “plug fit” wooden socket with a conical interior shape.
What is socket flexion?
Socket flexion/extension is named for the alignment it produces in the most distal residual joint. socket flexion moves knee joint center anterior relative to GRF, increasing heel lever, thus promoting LR knee flexion.
What does a secure and dependable suspension provide when using a transfemoral prosthesis?
Secure and dependable suspension enhances proprioception and provides the feeling that the prosthesis is more a part of the wearer.
How does a transfemoral prosthetic work?
A trans-femoral prosthesis is an artificial limb that replaces any amputated limb above the knee. The prosthesis is made from a high-quality raw material known as polypropylene. It has several components which fit together to construct the final piece.
What does the word transfemoral mean?
1 : passing through or performed by way of the femoral artery transfemoral angiography. 2a : occurring across or involving the femur transfemoral amputation. b : having undergone transfemoral amputation a transfemoral amputee also : suitable for use following transfemoral amputation transfemoral prostheses.
What is quadrilateral socket?
The quadrilateral socket is a rectangular shaped socket and uses opposing forces to keep the ischial tuberosity (also known as your sit bone) upon a ledge built into the socket. In certain cases quadrilateral sockets can also help reduce rotation of the prosthesis. …
What are the different types of transfemoral socket?
2. Compare and contrast the design, fit, and function of the four most popular transfemoral socket designs: quadrilateral, ischial containment, Marlo Anatomical Socket (MAS), and subischial. 3.
How does a transfemoral amputation affect the thigh muscles?
Aft er a transfemoral amputation, very litt le, if any, weight can be borne directly on the end of the residual limb. In addition, transection of the femur creates thigh muscles that are out of balance as the residual fl exor and abductor muscle groups overpower the residual extensors and adductors.
What is the shape of the transfemoral residual limb?
The shape of the residual limb is likely to be a tapered cylinder so that donning a prosthesis is less difficult. Suspension can be challenging, however, as a result of this cylindrical shape of the residual limb. The fleshiness of the transfemoral residual limb presents an opportunity for suction suspension.
What is a transfemoral symmetry liner?
For suspension, a transfemoral Symmetry liner was used in conjunction with an ePulse (Ottobock) electronic pump that provided VAS on both sockets. The trimline of the rigid frame in both sockets was lined with soldering iron to ensure clear definition during X-ray and fluoroscopy and to allow socket measurements.
