Ischial containment socket

Ischial containment socket

Unlike the quadrilateral socket the ischial containment socket holds the ischial tuberosity (sit bone) within the socket. This results in no one specific point being the main weight bearer within the socket. By containing the ischial tuberosity on the lateral side and the ischial ramus medially a bony lock is created.

The ischial containment socket provides the user with superior control when compared with the quadrilateral socket. This makes it a better socket choice for those who are more active. The increased control also results in increased stability making it ideal for those with a shorter residual limb or hip weakness.
