Transradial Socket Design Suspension

Question 1

The goals of transradial prosthetic socket design are:

Answer 1

• Control of socket rotation
• Facilitation of pronation and supination of terminal device
• Appropriate socket trim lines
• Selection of wrist shape

Question 2

Socket rotation in short or very short amputations can be controlled by one of two general approaches. The traditional approach is to apply rigid elbow joints to the prosthesis. Another form of rotational control can be gained by a self-suspending socket design. Short or very short self-suspending socket designs encompass the medial and lateral epicondyles.

Answer 2

True

Question 3

The Muenster socket has Supra-epicondylar trim lines but extends up posterior above the olecranon. This socket also extends into the cubical fold. As a result, the flexion and extension are limited to a range of seventy degrees from:

Answer 3

35-105 degrees

Question 4

For self suspending body powered prosthetic design sockets with functional terminal devices:

Answer 4

A figure of 9 harness is indicated
