Prosthetics
Sockets & Liners
The critical interface — digitally fit for comfort, suspension and control.
What it addresses
In prosthetic rehabilitation, the interface between the residual limb and the prosthesis determines long-term comfort, stability, and functional success. For hospitals, rehabilitation centres, and orthopaedic clinics, dependable socket fabrication and liner selection are critical to reducing complications, improving compliance, and achieving measurable mobility outcomes.
Key Benefits
- Precision volume management
- Reduced pistoning & shear
- Rapid comfort adjustments
- Consistent, repeatable fit
How it's made
3D Scan
High-resolution capture of the patient's anatomy — no plaster casting.
CAD/CAM Design
Engineers refine geometry, alignment and material zones digitally.
In-House Fabrication
3D printed or milled, then hand-finished by certified technicians.
Fit & Approval
Digital and clinical fit verification before final delivery.
Clinical Foundations
Institutional Scope & Biomechanics
In prosthetic rehabilitation, the interface between the residual limb and the prosthesis determines long-term comfort, stability, and functional success. For hospitals, rehabilitation centres, and orthopaedic clinics, dependable socket fabrication and liner selection are critical to reducing complications, improving compliance, and achieving measurable mobility outcomes.
Quantum Medical works closely with prosthetic and rehabilitation teams to design and fabricate high-precision sockets, liners, and suspension systems tailored to individual anatomical and functional requirements.
Our approach combines detailed clinical assessment, advanced fabrication methods, and coordinated follow-up support to ensure consistency across care pathways.
Core Engineering Focus
Sockets – The Foundation of Prosthetic Success
A well-designed socket is the core structural component of any prosthesis. It ensures secure suspension, balanced pressure distribution, and biomechanical alignment—especially important for users who rely on their prosthesis for extended daily wear.
Clinically Supports Recovery By
- Residual limb shape and volume management
- Soft tissue condition and scar protection
- Bony prominences offloading & pressure tolerance
- Activity level and dynamic load-bearing demands
- Long-term rehabilitation milestone alignment
Protocol Benefits
- Specific Weight-Bearing Sockets – Direct pressure toward tolerant regions while relieving sensitive areas
- Total Surface Weight-Bearing Sockets – Distribute load evenly across residual limb to improve proprioception
- Silicone, TPE & Polyurethane (PU) material interface selection
- Pin-Lock, Passive Vacuum & Active Vacuum suspension security
- Reduced pistoning, enhanced balance & skin breakdown prevention
Spinal Orthotic Systems for Clinical Practice
Custom Socket Designs
Anatomical Fit & Load Distribution
Specific Weight-Bearing Sockets
Engineered to direct weight-bearing pressure toward pressure-tolerant anatomical regions while relieving sensitive bony prominences.
Total Surface Weight-Bearing Sockets
Designed to distribute load evenly across the entire surface area of the residual limb to improve comfort, proprioception, and circulation.
Protective Liners & Material Interfaces
Comfort, Friction Reduction & Tissue Preservation
Silicone Liners
Durable medical silicone providing consistent suspension control and high mechanical stability for active users.
TPE (Thermoplastic Elastomer) Liners
Soft, flexible, and skin-friendly material infused with mineral oils for sensitive skin and tissue care.
Polyurethane (PU) Liners
Flowable material providing excellent pressure distribution and shock absorption for bony or irregular residual limbs.
Suspension Systems
Stability Supporting Rehabilitation Progression
Shuttle Lock (Pin-Lock) System
Secure mechanical attachment for predictable engagement and easy donning/doffing.
Passive Vacuum System
Enhances limb-socket contact through negative pressure and one-way expulsion valves.
Active Vacuum System
Advanced electric or mechanical pump providing superior volume management, zero pistoning, and maximum suspension stability.
