Joints Flashcards
What are some immune-mediated joint conditions?
Rheumatoid arthritis and ankylosis spondylitis
What are some degenerative joint disorders?
Osteoarthritis aka degenerative joint disease
What is the most common joint disorder?
Osteoarthritis
What is affected with osteoarthritis?
Degeneration of articular cartilage occurs (collagen)
What substance is decreased in OA and what is the result of that reduction?
Decreased proteoglycans leading to matrix breakdown
Is OA largely inflammatory?
Not necessarily (“itis”
What causes OA?
Both mechanical wear and tear from aging along with a genetic influence
Which type of OA occurs without trauma and is common among adults?
Primary
Which type of OA is insidious in onset and is oligocarticular in nature?
Primary
Which type of OA is associated with trauma or obesity, deformity, or a systemic disease?
Secondary
Which type of OA involves a predisposing injury or deformity?
Secondary
What are the common specific locations for OA?
Spine (cervical, lumbar), DIP joints, 1st metacarpal joint, 1st tarsal metatarsal joint
What is the most common location for OA in females?
Knees and hands
What is the most common location for OA in males?
Hips
What occurs to the intervertebral discs and is seen on X-ray during OA?
Dehydration of discs
When can inflammation in OA develop?
After full blown degeneration
What are the functions of articular cartilage?
Decrease friction and shock allow load absorption
OA disrupts the function of what cells?
Chondrocytes
What are risks for OA?
Mechanical stress, age 50s-60s, genetics, increased bone density, increased circulating estrogen
Insidious onset, deep/achy pain, crepitus, decreased range of motion, and worse pain the morning are all associated with what joint condition?
OA
What affect can osteophytes in OA have on nerves?
Possible impingement of nerve roots
What is the treatment for OA?
Palliative: ice, heat, NSAIDs, adjust, joint replacement
What is ankylosis?
Abnormal fusion of joints
Is ankylosis present in OA?
No no no no no no noooooo
