CPT Maintenance, Repairs, & Quality Assurance

Question 1

What is the primary goal of routine maintenance for a prosthesis?

Accepted Answer

Ensure function and safety

Answer

Routine maintenance for a prosthesis is crucial to ensure all components are working correctly, safely, and efficiently. Regular checks help identify wear and tear, prevent potential failures, and maintain optimal performance, which directly impacts the user's mobility, comfort, and overall well-being.

Question 2

Which component is most likely to require regular adjustment in a lower limb prosthesis?

Accepted Answer

Pylon alignment

Answer

The pylon alignment, which refers to the angle and position of the prosthetic components relative to each other and the user's body, significantly impacts gait, balance, and comfort. Even minor shifts can cause discomfort or instability, making it the most common component requiring regular adjustment to maintain optimal function.

Question 3

Why is documentation important during prosthetic repair?

Accepted Answer

To ensure traceability and quality tracking

Answer

Detailed documentation during prosthetic repair is essential for maintaining a comprehensive history of the device, including repairs, adjustments, and component replacements. This record ensures traceability, helps track the quality and longevity of parts, and provides valuable information for future maintenance, warranty claims, and patient care.

Question 4

Which is a sign that a prosthesis may need repair or adjustment?

Accepted Answer

Audible noises during walking

Answer

Audible noises such as squeaking, clicking, or clunking during walking are often indicators of mechanical issues within the prosthesis, such as loose components, worn joints, or improper alignment. These noises signal that the device may require inspection, repair, or adjustment to restore proper function and prevent further damage.

Question 5

What does a quality assurance (QA) process involve in prosthetics?

Accepted Answer

Verifying conformity to standards

Answer

A quality assurance (QA) process in prosthetics involves systematically checking and verifying that all aspects of fabrication, fitting, and repair meet established industry standards, regulatory requirements, and patient specifications. This ensures the prosthesis is safe, functional, durable, and provides the best possible outcome for the user.
