Compared to metal-on-metal implants, ceramic-on-ceramic implants have: a. Extremely low wear rates and provoke a minimal inflammatory response. b. High wear rates and moderate debris formation. c. A tendency to provoke the development of soft-tissue pseudotumors. d. A low risk of shattering in response to high-impact activities. 138. Disadvantages of a cemented total hip arthroplasty include: a. The need for healthier, more vigorous bone, particularly of the femur. b. A risk that the cement may crack and loosen, especially in more active patients. c. The need for increased surgical accuracy for accurate placement of cement compounds. d. Additional weight-bearing restrictions during the first 6 weeks of recovery. 139. Hip resurfacing is an option for patients who are?
a. The femur to swing clear of the pelvis with each stride. b. More depth and stability of the joint at the acetabular socket. c. A greater surface area for femoral articular cartilage. d. For a wider base of support to enhance balance and proprioception. 131. A more acute angle of inclination is? a. Associated with male patients. b. Associated with a high rate of hip dislocation. c. Associated with lower extremity genu valgus. d. Associated with lower extremity genu varus. 132. With the progression of hip osteoarthritis (OA), reduced flexibility can occur most notably in the hip: a. Abductors. b. Adductors. c. Extensors. d. Flexors. 133. Reduced passive range of motion of the hip joint occurs in OA due to:
a. Loose bodies of cartilage in the joint. b. Weakness of the hip musculature. c. Inflammation of the surrounding bursae.
d. Adaptive shortening of the joint capsule and ligaments. 134. Symptoms arising from OA of the hip are most frequently
a. Allergic to metal implants. b. Younger and more active. c. Diagnosed with hip dysplasia. d. Older than age 55.
