External lower-limb prosthesis structural/alignment component

External lower-limb prosthesis structural/alignment components are mechanical parts designed to connect and stabilize different parts of a lower-limb prosthesis, such as sockets, knee joints, or ankle-foot units. They ensure the prosthesis remains intact while allowing precise adjustments to alignment—like shifting or tilting components—to match the patient’s anatomy and movement needs.

These components are typically classified based on their role in structural support or alignment, often regulated as medical devices under relevant jurisdictions. They are usually supplied as part of a full prosthesis system, requiring customization to fit individual patients and may be reusable or single-use depending on the design and material.
