Osteoarthritis (Smarty PANCE) Questions and Answers
Characterized by asymmetric joint stiffness, that How does OA affect the joint spaces?-
worsens as the day progresses- Osteoarthritis typically causes narrowed
Osteoarthritis joint spaces
Osteophytes found at the distal interphalangeal Name three common radiographic findings in OA-
joints in osteoarthritis- Heberden nodes OA causes subchondral cysts, narrowing of
(think HD TV - Haberdeen = distal) the joint space, and joint sclerosis on radiography
Osteophytes found at the proximal Does the synovial fluid analysis in osteoarthritis
interphalangeal joints in osteoarthritis.- reveal low or high levels of white blood cells?-
Bouchard nodes (Think BP gas - Bouchard Synovial fluid analysis in osteoarthritis
= proximal) reveals low levels of white blood cells
Which joints of the hands are most commonly What are the most common symptoms and signs
affected by osteoarthritis?- The distal of osteoarthritis?- The most common
interphalangeal (DIP) joints of the fingers are symptoms and signs of osteoarthritis are:
