Quadrilateral socket

Quadrilateral socket

The quadrilateral socket is a rectangular shaped socket and uses opposing forces to keep the ischial tuberosity (also known as your sit bone) upon a ledge built into the socket. This ledge is the main weight bearing area of the socket allowing you to stand comfortably and securely within the socket. In certain cases quadrilateral sockets can also help reduce rotation of the prosthesis.

Quadrilateral sockets are better suited to those with a muscular and longer residual limb however our experienced prosthetists will be able to give specific suitability advice following an assessment.

The use of opposing forces helps to provide suction suspension through negative pressure, this can then be complemented by other suspension methods i.e. belts.

payment options
