What Are Prosthetic Sockets & Liners?
A prosthetic socket is the primary interface connecting a residual limb to the prosthetic device. Its design is an important consideration for load transfer, device control, support, and suspension.
Prosthetic liners are flexible interface products used in many prosthetic systems between the residual limb and socket. Depending on the material and design, liners may provide cushioning, assist with suspension, or help manage contact between the skin and prosthetic socket.
Suspension systems help maintain the prosthesis in position during intended activities. Socket, liner, and suspension selection depends on residual limb anatomy, skin and tissue condition, functional requirements, and professional assessment.

Passive Vacuum & Suction Suspension Systems
Suspension systems that utilize pressure differences to maintain intimate socket retention, utilizing airtight sealing sleeves, seal-in liners, or expulsion valves.
Main Purpose
Eliminates distal pin traction and distributes suspension forces across the residual limb surface, promoting stable limb-to-socket contact during daily ambulation.
Key Considerations
- Requires an airtight socket seal maintained by sleeves or liner seals
- One-way expulsion valve vents air during weight-bearing and prevents re-entry
- Reduces relative movement between limb and socket during gait swing phase
- Sealing components must be kept clean and inspected for micro-punctures
Active Vacuum Prosthetic Suspension
Advanced suspension technology utilizing a mechanical stride-activated pump or electronic micro-pump to generate and actively regulate sub-atmospheric pressure inside the socket.
Main Purpose
Designed to support appropriate prosthetic suspension and interface management according to individual clinical needs, helping stabilize residual limb volume throughout wear.
Key Considerations
- Maintains consistent elevated negative pressure across the entire socket surface
- Mechanical pumps generate vacuum during gait cycles; electronic pumps run on rechargeable power
- Helps manage residual limb volume fluctuations and reduces relative socket motion
- Requires strict adherence to socket seal maintenance and pump operating instructions
