What are key components of a below-the-knee prosthesis?

A below-the-knee prosthesis, also known as a transtibial prosthesis, typically consists of key components that play essential roles in its functionality and support. The correct choice lists the socket, pylon, and foot component as the primary elements of such a prosthesis.

The socket is a custom-fitted part that allows for the connection between the residual limb and the prosthesis. It is designed to provide a secure, comfortable fit, and helps to accommodate the unique shape of the amputee's limb.

The pylon serves as the structural component that provides support and stability. It is usually made from lightweight materials such as aluminum or carbon fiber, connecting the socket to the foot component. This connection allows for effective weight distribution and balance during ambulation.

The foot component is crucial for mobility, offering various functionalities that may include shock absorption and the ability to adapt to different surfaces. There are various types of foot components, ranging from basic designs to more advanced versions that simulate natural ankle movement.

In contrast, the other options include components that are not characteristic of a below-the-knee prosthesis. For instance, a support strap and knee joint pertain to above-the-knee prosthetics, while a thigh brace is not used in below-the-k
