Top 10 Questions for Orthotist/Prosthetist Interview

1. Describe the key components of a transtibial prosthesis and discuss the role of each component in the overall function of the prosthesis.

Sample Answer:

• Socket: The socket is a custom-fabricated component that fits snugly around the residual limb. It provides suspension, support, and control for the prosthesis.
• Pylon: The pylon is a vertical strut that connects the socket to the foot. It is usually made of metal or composite materials and transmits the weight of the user to the ground.
• Foot: The foot is the component that contacts the ground and provides stability and support. There are many different types of feet available, each with its own unique design and function.

2. Explain the biomechanical principles of gait and how they influence the design of prosthetic devices.

Sample Answer:

Normal Gait:

• Stance Phase: The foot is in contact with the ground, providing support and propulsion.
• Swing Phase: The foot is lifted from the ground and swings forward to prepare for the next step.

Prosthetic Gait:

• Modified Stance Phase: The prosthetic foot may not be able to fully plantarflex, which can reduce propulsion and stability.
• Modified Swing Phase: The prosthetic foot may be heavier than a biological foot, which can make it more difficult to swing forward.

Design Implications:

• Prosthetic feet are designed to minimize these biomechanical limitations and restore normal gait patterns as much as possible.
• Factors such as the type of amputation, level of activity, and patient preferences are considered when designing prosthetic devices.

3. Discuss the different types of materials used in the fabrication of prosthetic devices and their advantages and disadvantages.

Sample Answer:

Polypropylene:

• Advantages: Lightweight, durable, waterproof
• Disadvantages: Can be rigid, not as comfortable for some users

Carbon Fiber:

• Advantages: Strong, lightweight, flexible
• Disadvantages: Expensive, can be uncomfortable for some users

Titanium:

• Advantages: Strong, lightweight, corrosion-resistant
• Disadvantages: Expensive, can be difficult to work with

Silicone:

• Advantages: Comfortable, flexible, waterproof
• Disadvantages: Can be less durable than other materials

4. Describe the different casting techniques used in the fabrication of orthotics and prosthetics.

Sample Answer:

Positive Casting:

• A positive mold is made of the affected area.
• This is used to create a positive model of the area, which is then used to fabricate the orthotic or prosthetic device.

Negative Casting:

• A negative mold is made of the affected area.
• This is used to create a positive model of the area, which is then used to fabricate the orthotic or prosthetic device.

Direct Casting:

• The orthotic or prosthetic device is directly cast onto the affected area.
• This technique is often used for custom-fitting devices.

5. Explain the role of computer-aided design and manufacturing (CAD/CAM) in the production of orthotics and prosthetics.

Sample Answer:

• CAD/CAM is used to design and manufacture orthotics and prosthetics with greater precision and efficiency.
• CAD software is used to create digital models of the affected area, which are then used to design the orthotic or prosthetic device.
• CAM software is then used to control the fabrication process, ensuring that the device is manufactured to the exact specifications of the design.

6. Discuss the different types of gait analysis techniques and their applications in orthotics and prosthetics.

Sample Answer:

2D Gait Analysis:

• Uses cameras to capture images of the patient’s gait from two different angles.
• Can be used to assess joint angles, range of motion, and other gait parameters.

3D Gait Analysis:

• Uses multiple cameras to capture images of the patient’s gait from all angles.
• Can provide more detailed information about the patient’s gait, including joint rotations and muscle activity.

Instrumented Gait Analysis:

• Uses sensors to measure the forces and moments acting on the body during gait.
• Can be used to diagnose gait disorders and evaluate the effectiveness of orthotic and prosthetic interventions.

7. Explain the principles of pedorthics and how they are applied in the management of foot and ankle conditions.

Sample Answer:

• Pedorthics is the study of the foot and its biomechanics.
• Pedorthists use a variety of techniques to assess foot problems and develop custom orthotics (foot supports) to correct or accommodate foot deformities.
• Pedorthic interventions can help to manage a variety of foot and ankle conditions, such as plantar fasciitis, heel spurs, and flat feet.

8. Discuss the role of the orthotist/prosthetist in the interdisciplinary team approach to patient care.

Sample Answer:

• Orthotist/Prosthetists work closely with other healthcare professionals, such as physicians, physical therapists, and occupational therapists, to provide comprehensive care to patients.
• They contribute their expertise in the assessment, design, fabrication, and fitting of orthotics and prosthetics.
• By working together, the interdisciplinary team can develop a treatment plan that meets the individual needs of each patient.

9. Describe the ethical considerations that orthotist/prosthetists must be aware of in their practice.

Sample Answer:

• Orthotist/Prosthetists must always act in the best interests of their patients.
• They must be honest and transparent about the benefits and risks of their interventions.
• They must respect the patient’s autonomy and decision-making process.
• They must maintain confidentiality and protect the patient’s privacy.

10. How do you stay up-to-date on the latest advancements in orthotics and prosthetics?

Sample Answer:

• Read peer-reviewed journals and attend industry conferences.
• Participate in continuing education courses.
• Network with other orthotist/prosthetists and healthcare professionals.
• Research new products and technologies.

Orthotist/Prosthetists assess, design, fabricate, fit and maintain orthotics and prosthetics to restore mobility and improve function in patients with physical impairments.

1. Patient Assessment and Evaluation

Conduct comprehensive patient evaluations to determine their specific needs and goals.

• Take detailed patient histories, perform physical examinations, and review medical records.
• Analyze patient’s gait, posture, and range of motion to identify areas of impairment.

2. Design and Fabrication of Orthotics/Prosthetics

Design and fabricate custom-made orthotics or prosthetics based on patient assessments.

• Use specialized software and equipment to create designs that meet patient’s unique requirements.
• Select and use appropriate materials, such as plastics, metals, and composites, to fabricate devices.

3. Fitting and Maintenance

Fit and adjust orthotics or prosthetics to ensure proper fit and comfort.

• Instruct patients on proper use and care of devices.
• Monitor patients’ progress and make necessary adjustments or repairs to devices.

4. Collaboration and Communication

Collaborate with other healthcare professionals, such as physicians, physical therapists, and occupational therapists.

• Provide consultation and education to patients, families, and other caregivers.
• Maintain accurate patient records and document all aspects of care.
