Prosthetic Socket & Suspension Systems

We believe the socket is the foundation of your mobility—the critical interface between your limb and your technology.

The Foundation of Comfort, Fit, and Control

Your prosthetic socket and suspension system are the most critical components of your prosthesis. They directly impact comfort, stability, and how naturally your device functions.
At Falk Prosthetics & Orthotics, we specialize in designing and fabricating custom socket and suspension solutions that provide a secure fit, reduce discomfort, and improve overall mobility—so you can move with confidence every day.

What Is a Prosthetic Socket?

The prosthetic socket is the part of your prosthesis that fits over your residual limb. It serves as the primary connection point between your body and the prosthetic device.
A properly fitted socket is essential for:

• Even weight distribution
• Reduced pressure points and irritation
• Improved control and movement
• Long-term limb health

We design each socket to match your unique anatomy using precise measurements and advanced fabrication techniques.

What Is a Suspension System?

The suspension system keeps your prosthesis securely attached to your limb. It prevents slipping, improves stability, and ensures the prosthesis moves in sync with your body.
The right suspension system can:

• Increase confidence during movement
• Reduce pistoning (up-and-down movement)
• Improve balance and control
• Enhance overall comfort

Socket Designs We Fabricate



Total Surface Bearing (TSB)

Distributes pressure evenly across the entire residual limb; ideal for gel-liner and elevated vacuum systems.



Patellar Tendon Bearing (PTB)

Strategic weight-bearing design that loads specific anatomy while providing relief for sensitive areas.



Ischial Containment (IC)

Advanced brim design that stabilizes the femur to improve control and gait efficiency for above-knee users.



Sub-Ischial Hybrid

Lower-profile brims and flexible inner sockets designed for maximum comfort and increased range of motion.



RevoFit® Adjustable Socket

Features a dial-based system that lets you easily adjust socket fit and compression throughout the day—even through clothing.

Suspension & Adjustment Options

Suction

Uses a one-way valve to create a skin-to-socket seal. Offers a very secure hold without distal traction and a low-profile look.

Elevated Vacuum

Active pumps maintain a constant seal, which manages limb volume changes and improves contact throughout the day.

Pin-Lock (Shuttle)

A gel liner with a mechanical pin that clicks into a lock. It is fast, intuitive, and provides audible security.

Lanyard System

A strap threads through the socket and secures externally. Excellent for those with limited hand strength.

Sleeve Suspension

A flexible external sleeve creates a seal above the socket rim. Often used as primary suspension or as an extra safety layer.

RevoFit® Adjustable Socket

Incorporates a dial-based lacing system that allows you to adjust the compression and fit of your socket through your clothing as your limb changes throughout the day.

Martin Bionics — Socket-less Socket™

We offer the innovative Socket-less Socket™ from Martin Bionics to provide a breakthrough in prosthetic comfort. Unlike traditional rigid designs, this features a flexible, open structure that adapts to your limb throughout the day. This approach helps improve circulation, reduces pressure points, and accommodates volume changes naturally. It is a lightweight, breathable option designed to enhance mobility for both new and experienced users.

Slingshot Bionics — Slingshot Socket

The Slingshot Socket focuses on dynamic flexibility and performance. Built with a specialized fabric-based structure, it moves naturally with your body while maintaining secure support. This reduces the common discomfort and skin irritation associated with more rigid traditional sockets. It is designed specifically for an active lifestyle, maximizing daily comfort without sacrificing stability.

Frequently Asked Questions About Prosthetic Socket & Suspension Systems

How do I know if my socket fits properly?

A proper fit should feel secure without pain, excessive pressure, or movement.

What is pistoning and how is it prevented?

Pistoning is vertical movement inside the socket. Proper suspension systems help eliminate this issue.

How often should a socket be replaced?

It depends on changes in limb shape, activity level, and wear—but adjustments are often needed over time.

Can my suspension system be upgraded?

Yes—many patients transition to more advanced systems as their needs evolve.

What if I’m experiencing discomfort?

You should schedule an evaluation as soon as possible to prevent further issues.
