External lower-limb prosthesis socket, custom-made

An external lower-limb prosthesis socket is a custom-fitted component designed to interface directly with a residual limb after amputation, providing critical support, stability, and suspension. It acts as the foundational connection between the patient’s limb and the prosthetic system, ensuring comfort and functional mobility for daily activities or rehabilitation.

These sockets are individually crafted using patient-specific measurements, often via casting or 3D imaging, and may incorporate materials like carbon fiber or thermoplasts. While the socket itself is the primary structure, additional prefabricated components—such as liners or suspension systems—are frequently added to enhance fit and performance.
