Total questions: 15
Worksheet time: 8mins
What are the main types of hip prostheses?
Knee arthroplasty
Total hip arthroplasty, hemiarthroplasty, resurfacing arthroplasty
Ankle fusion
Shoulder replacement
What are the common surgical indications for hip replacement?
Chronic back pain
Mild joint pain
Severe osteoarthritis, rheumatoid arthritis, avascular necrosis, hip fractures, significant hip pain or disability.
Recent hip surgery
What are some potential complications after hip surgery?
Potential complications after hip surgery include infection, blood clots, dislocation, nerve damage, and persistent pain.
Enhanced bone density in the hip area
Increased flexibility in the hip joint
Improved mobility immediately after surgery
What materials are commonly used in hip prosthetics?
Titanium, polyethylene, ceramics, and titanium alloys.
Plastic, wood, copper, and zinc
Aluminum, rubber, glass, and steel
Silicone, lead, fabric, and iron
How should a hip prosthesis be maintained post-surgery?
Regular follow-up, physical therapy, avoid high-impact activities, monitor for complications.
Ignore any discomfort
Engage in extreme sports
Only use pain medication
What is the difference between cemented and uncemented prostheses?
Cemented prostheses are fixed with bone cement for immediate stability, while uncemented prostheses allow for bone ingrowth for stability over time.
Cemented prostheses are used only in younger patients, while uncemented prostheses are for older patients.
Cemented prostheses are made of metal, while uncemented prostheses are made of plastic.
Cemented prostheses require more recovery time than uncemented prostheses.
What factors influence the choice of prosthesis type?
Cost of the prosthesis
Availability of local clinics
Color preferences of the patient
Factors influencing the choice of prosthesis type include amputation level, patient age, activity level, limb condition, lifestyle, and technology availability.
What are the signs of infection after hip surgery?
Signs of infection after hip surgery include redness, swelling, warmth, pain, discharge, fever, and chills.
Complete absence of pain or discomfort
Increased appetite and weight gain
Improved mobility and flexibility
How long is the typical recovery period after hip replacement?
12 to 18 weeks for complete healing
3 to 4 months for significant improvement
6 to 12 weeks for significant improvement, up to 6 months for full recovery.
1 to 2 weeks for full recovery
What role does physical therapy play in recovery?
Physical therapy is only for athletes recovering from injuries.
Physical therapy is primarily focused on mental health support.
Physical therapy has no impact on mobility or pain reduction.
Physical therapy plays a crucial role in recovery by enhancing mobility, reducing pain, and restoring function.
What are the risks associated with hip prosthesis dislocation?
Risks include pain, loss of mobility, nerve damage, and potential need for revision surgery.
Enhanced muscle strength
Improved joint flexibility
Increased bone density
How can patients reduce the risk of blood clots after surgery?
Avoid all physical activity for a month
Increase salt intake to retain water
Use hot packs on the legs regularly
Stay active, follow exercises, wear compression stockings, stay hydrated, and take anticoagulants if prescribed.
What lifestyle changes may be necessary after receiving a hip prosthesis?
Completely avoid any form of exercise
Increase weight-bearing activities immediately
Avoid high-impact activities, use assistive devices, participate in physical therapy, and modify home environment.
Engage in extreme sports regularly
What is the average lifespan of a hip prosthesis?
10 to 15 years
25 to 30 years
5 to 10 years
15 to 20 years
What advancements have been made in hip prosthetic technology?
Standardized implants for all patients
Advancements include durable materials, minimally invasive techniques, 3D printing for custom implants, and smart prosthetics with sensors.
Use of outdated materials
Increased recovery time
