musculoskeletal MS disorders Flashcards
osteoporosis
Characterized by reduced bone mass- > decreased bone strength.
Consequence: bone fracture
osteoporosis prevention
- Primary osteoporosis
- Low Vit. D level
- To prevent: consume adequate calcium (1,000 – 1,300 mg/day) and Vitamin D
- Engage in weight-bearing exercises
- Lifestyle modification: avoid smoking, alcohol, caffeine, carbonated beverages
- Secondary Osteoporosis- due to medications or diseases that affect bone metabolism.
primary osteoporosis
occurs among women after menopause and men later in life.
Women- decrease in estrogen
Men- decrease in testosterone
secondary osteoporosis
due to medications or diseases that affect bone metabolism
- Use of corticosteroids, excessive alcohol intake
- Specific disease: celiac disease; hypogonadism
- Certain medications: anticonvulsants, thyroid replacements, anti-estrogen, androgen inhibitors, PPI.
osteoporosis management
Diet rich in calcium and Vit D
Regular weight-bearing exercises (20-30 min)
Hormone replacement therapy after menopause
management of osteoporosis pharm
Calcium supplement with Vit. D tablet- take with Vit C/high vit. C drink
Osteoporosis Medications: (page 1207, Table 53.5) look in book for administration/special considerations
vitamin k2
new supplement –> absorption of calcium into bone (from blood to bone)
fracture management
fracture of hip- managed by joint replacement ; or close or open reduction with internal fixation
Compression fracture- treat conservatively
dx for osteoporosis
- Xray- can reveal low bone density and fracture
- DXA (dual x-ray absorptiometry)
- QCT (quantitative computed tomography)
- Peripheral Quantitative Ultrasound
DXA
Usually done in the hips or spine; used to screen early changes in bone density
health teaching: lie flat or stay x-ray table while the scan is going on, pt have to lie still/ follow instruction (ex: not good for people with dementia)
Peripheral Quantitative Ultrasound
This is inexpensive, portable and low-risk method to determine osteoporosis
gerontologic consideration
- Women older than 80- prevalence is 50%
- Men have higher mortality than women after sustaining hip fracture b/c - incidence of living alone in men is higher, men have less compliance
- Older adults absorb dietary calcium less efficiently and excrete more readily via kidneys.
osteoarthritis/ degenerative joint disease
OA is a noninflammatory degenerative disorder of the joints.
- Usually on weight-bearing joints- hips/knees
- Can also be seen in PIP (proximal interphalangeal) joints, DIP joints
osteoarthritis patho
The articular cartilage breaks down- > progressive damage to the underlying bone- > formation of osteophytes (“bone spurs”)(protrude into the joint space)- > joint space is narrowed- > decreased joint movement.
The joint can progressively degenerate!
osteoarthritis risk factors of disease and progression
older age; female gender; obesity; certain occupations; engaging in sports activity; history of previous injuries; genetic predisposition.
