What does the socket of a prosthesis do?

The socket of a prosthesis serves as the interface between the residual limb and the prosthetic device, making it a critical component for ensuring proper fit, comfort, and functionality. It is designed to conform closely to the shape of the residual limb, which allows for better control and alignment of the prosthesis during movement.

A well-designed socket helps to distribute forces evenly across the limb, reducing the risk of pressure sores or discomfort. This intimate fit is essential for the user to achieve effective weight-bearing and stability during activities, as well as to optimize the biomechanical function of the prosthesis during ambulation. The socket also plays a significant role in the overall effectiveness of the prosthetic device, as proper alignment and contact with the limb can enhance proprioception and confidence in mobility.

Additionally, while the socket does contribute to providing suspension, the main function focuses on the direct connection and interface role, which is vital for the user’s experience and interaction with the prosthesis.
