How does the socket work?

Socket selection and fit are the most important elements in your recovery and achieving your goals. A prosthetic socket serves as the interface between your residual limb and the rest of your prosthesis. It’s what connects you to your leg. There are several common socket designs optimized for particular anatomies and activities. During your prosthetic evaluation, our prosthetist will review different socket designs and work with you to determine what you need.  Socket selection and fit are the most important elements in your recovery and achieving your goals. Compared to other providers Eschen has achieved leading Socket Comfort Scores based on feedback from our patients.

Prosthetic Socket Types

Ischial

Ischial Weight Bearing sockets are designed with an inner flexible socket and an outer laminated resin frame. The flexible inner socket is designed to be fitted around your ischium and ramus which are part of your pelvic skeletal anatomy. This creates a “bony lock” to stabilize the socket during walking and standing. The socket also has anatomical contours designed to support your muscular anatomy to provide control, weight-bearing, and support.

Musculoskeletal

HiFi sockets, also known as High Fidelity sockets, are musculoskeletal sockets designed with an inner flexible socket and outer laminated resin frame. The musculoskeletal socket does not fit around your pelvic anatomy like an Ischial weight-bearing socket. It provides four longitudinal struts that support the entire femur and allows muscle and soft tissue expansion to displace properly through uniquely designed windows. This biomechanical design provides improved socket control, suspension, and comfort. It does not fit into the groin as do other socket systems so it allows greater movement with improved comfort when walking and sitting.

HiFi + Musculoskeletal

Sub Ischial sockets are designed with an inner flexible socket and outer laminated frame. The trim lines are much lower than both the Ischial Containment and HiFi sockets. This socket requires the use of liners and vacuum suspension to create tissue firmness and provide support and suspension. It is best used on a patient with a longer and firmer residual limb. The socket provides for increased range of motion and improved comfort when walking and sitting.

Sub Ischial

Total Surface Weight Bearing

This socket system is designed to provide weight bearing and support evenly over the surface of the residual limb. It requires the patient to wear a silicone or urethane liner on the residual limb. It is suspended with either passive suction or elevated vacuum. The combination of total support, the liner, and suction suspension, provide a socket that is very comfortable, provides excellent biomechanical control, and allows improved function.

PTB

This is the traditional below knee prosthetic socket. It is designed with specific weight bearing areas. These are the patella tendon, which is just below your knee cap, either side of your tibia, and the inside and back of your calf. This socket design is generally used when patients wear a pin lock or traditional strap suspension.
