Transradial Harnessing and Cabling

Question 1

A transradial figure of 8 harness is indicated as a standard harness of suspension design for transradial prosthesis with flexible hinges

Answer 1

True

Question 2

Because a significant amount of force is generated as the patient pulls against the proximal cable, the attachment of the crossbar leather uses a single rivet for attachment to the triceps cuff.

Answer 2

False

Question 3

The goal of the cross-back strap is:

Answer 3

To prevent the upward migration of both control attachment straps in the case of the bilateral harness.

Question 4

The transradial shoulder saddle with chest strap is a unique design of transradial harness.

Answer 4

• excursion is generated by increasing the distance between the proximal attachment point of the control attachment strap and the cabling system
• the primary control motion is humeral flexion
• though scapular abduction remains a secondary control motion, it is more difficult to capture scapular abduction on the sound side due to the lack of the complete axilla loop

Question 5

In the Bowden cable system, a stainless ferrule is located at:

Answer 5

Both ends of the cable housing to finish the cut end of the housing.
