6.2.2 Determining the socket size and socket length
The reference value for the required socket length is:
Required socket length = residual limb length
INFORMATION
For this product, the socket length is defined as the distance between the bottom of the socket
and the medial socket brim, measured in the direction of the longitudinal axis of the socket.
The exact socket length can be determined by trying several socket lengths, preferably in the
course of using a check socket.
INFORMATION
Pressure on the medial socket brim can be reduced by reducing the socket length.
Pressure on the residual limb end can be reduced by increasing the socket length.
The socket size can be determined based on the measured residual limb circumferences and the
residual limb length. Use the chart below for this purpose.
