 How to choose the correct liner size
a) Measure the circumference of the residual limb at 4 cm from the distal end.
b) Choose the liner size corresponding to this measurement or the next smaller size, respectively.
c) Do not choose a liner whose size exceeds the measurement taken.
d) Never reduce by more than one liner size in order to avoid unnecessarily high compression.

In locking liners, a matrix with 10 cm length is integrated as a standard.This matrix should end below the head of the fibula and must not exceed it, as this could result in problems during knee flexion.
