A below knee prosthesis, also known as a transtibial prosthesis, is a specialized artificial limb designed for individuals who have undergone a below knee amputation. This type of prosthesis aims to restore mobility and functionality to the amputated limb, enabling the user to perform various activities.
The below knee prosthesis typically consists of three main components: a socket, a pylon, and a foot. The socket is custom-made to fit the individual's residual limb, providing a secure and comfortable connection between the limb and the prosthesis. It is designed to distribute the forces evenly and provide stability during movement.
The pylon is a lightweight and durable component that connects the socket to the foot. It offers support and flexibility, allowing for natural walking and absorbing shock during weight-bearing activities. The pylon may be adjustable in length to accommodate different user needs and activities.
The foot component of the below knee prosthesis plays a crucial role in providing stability, shock absorption, and propulsion. There are various types of prosthetic feet available, including solid ankle cushioned heels (SACH), energy-storing feet, and dynamic response feet. The choice of foot depends on factors such as the user's activity level, lifestyle, and specific needs.
Collaboration with a prosthetist, who is a healthcare professional specializing in prosthetics, is essential to ensure a well-fitting and functional below knee prosthesis. The prosthetist works closely with the individual to assess their specific needs, measure the residual limb, and customize the prosthesis for optimal comfort and mobility.
