What adjustment can be made if the ischial tuberosity of a TF amputee is not positioned correctly in the socket?

When the ischial tuberosity of a transfemoral amputee is not positioned correctly within the socket, it can lead to discomfort and improper weight distribution. Adding a sock, or more specifically, a ply of sock material, is a common adjustment that can help achieve a better fit. This method increases the volume within the socket, allowing for better alignment of the ischial tuberosity with the socket's design. By doing so, it provides additional support and redistributes pressure more evenly across the residual limb.

This adjustment is particularly useful because it is a non-invasive and easily reversible solution. It allows for fine-tuning in the socket fit without requiring major alterations to the prosthetic design or structure.

In contrast, increasing the socket depth could potentially lead to further complications by increasing pressure on the residual limb, while adding a pad to Scarpa's triangle may not effectively address the specific positioning issue concerning the ischial tuberosity. Replacing the liner, while it might seem like a feasible option for fitting issues, can be more resource-intensive and may not resolve the immediate problem of alignment.
