Osteoporosis is characterized by low bonemineral density and deterioration of bone tissue, increasing fragility of bone, and subsequent risk of fracture
Which type of scans are used to diagnosis osteoporosis?
Dual-energy x-ray absorptiometry (DEXA)
Which scores are used to guide diagnosis & decisionto treat osteoporosis?
What are the T scores for osteopenia vs. osteoporosis?
- Osteopenia: -1.0 to -2.5
- Osteoporosis: <-2.5
What is "ostepenia"?
Osteopenia is a condition where bone mineral density is lower than normal. It is considered by many doctors to be a precursor to osteoporosis.
At what age should women be screened for osteoporosis?
- women >65 y/o
- post-menopausal women <65 y/o with family history of osteoporosis
What is Primary osteoporosis?
Primary means there is no known cause.
What is Secondary osteoporosis?
- drug induced
- medical conditions
What three (3) factors does osteoporosis vary by?
- age (old > young)
- gender (female > male)
- ethinicity (caucasian & asian)
Clinical presentation of osteoporosis?
- shortened stature
- vertebra, hip, or forearm fracture
- bone pain (especially back pain, which could indicate vertebral compression fracture)
Kyphosis, also called roundback or Kelso's hunchback, is a condition of over-curvature of the thoracic vertebrae (upper back).
Lordosis is a medical term used to describe an inward curvature of a portion of the lumbar and cervical vertebral column
What are the two (2) types of bone?
- trabecular (vertebrae, wrist & ankle, ends of long bones)
Which type of bone is most susceptible to fracture?
Distinguish between osteoblasts vs. osteoclasts?
- Osteoblasts - bone formation
- Osteoclasts - bone destruction
Bone formation exceeds destruction during childhood.
At what age does the peak bone mass is reached?
Why are postmenopausal women prone to osteoporosis?
Following menopause, estrogen production declines and osteoclastic activity increases.
