For proper alignment, how much adduction should the socket have in a TF bench alignment?

The correct amount of adduction for a socket in transfemoral (TF) bench alignment is typically in the range of 6 to 7 degrees. This degree of adduction is essential for achieving optimal alignment of the prosthesis with the residual limb. Proper alignment facilitates better weight distribution, enhances stability during ambulation, and allows for more efficient use of energy while walking.

The specified range of 6 to 7 degrees has been determined to provide a balance between functionality and comfort. It helps in maintaining a natural gait pattern and minimizes the risk of complications such as excessive lateral thrust or instability. Achieving this alignment is crucial for maximizing the user's overall mobility and ensuring that the prosthesis performs effectively during various activities.

While other options provide different degrees of adduction, they do not align with the established norms for effective TF bench alignment, making them less suitable for ensuring optimal performance and comfort in the prosthetic fitting process.
