The Blatchford Comfort Liner is gentle on fragile skin and protects residual limbs with areas susceptible to shear force abrasion and pressure peaks. The fabric cover with integrated matrix contours perfectly to the limb and zonal stretch areas allow comfortable knee flexion but resist distal stretch which would result in the prosthesis slipping away from the body.

The Cushion and Locking options allow the ideal choice of proximal or distal pin lock suspensions. 

Integrated Matrix
Technical knitted outer cover for the Locking Liner has integrated distal matrix with uni-directional stretch to resist pistoning. The seamless knitting technology allows a smoother transition between the bi-directional and uni-directional stretch zones.

Stretch Zones
Proximal bi-directional stretch zone improves comfort and contouring and reduces shear force on the knee during flexion.

The Locking Liner features a super flexi-umbrella which inverts easily to facilitate optimal donning.

TendresseTM Silicone Lining
The TendresseTM silicone finish results in a low coefficient of friction which reduces shear stress on skin. In tests this measured 78% less than standard silicone.

Comfort Liner Clinical Evidence Reference

  • Clinical Evidence Overview

    There are two published literature reviews that discuss different aspects of lower limb prosthetic liner technology1,2.

    • The main purpose of prosthetic liners is to cushion the transfer of loads from the prosthetic socket to the residual limb1.
    • Based on load-displacement data from the compressive stiffness tests, silicone was one of three materials that were recommended for situations where it is desirable for the liner to maintain thickness and volume since these materials had the least non-recovered strain1,3.
    • Under cyclic compressive loading, silicone was one of two materials that had the greatest cycles to failure under compressive loading, while the Pedilin and polyurethane samples lasted orders of magnitude less1,4.
    • Prosthetic liners and sockets are highly resistive to heat conduction and could be a major contributor to elevated skin temperatures1,5.
    • There are reduced residual limb pressures with the silicone liner compared to other conditions (no liner; soft inserts) suggesting that silicone has an ability to distribute pressure evenly to the residual limb1,6.
    • In terms of patient outcomes, there was no clear preference between silicone and Pelite liners1,7.
