NR 601 Week 4 Osteoporosis Lecture
- Osteoporosis
- Metabolic skeletal disease
- Decrease in bone mass and micro architectural deterioration of bone tissue – consequent increase in bone fragility and susceptibility to fracture
- WHO definitions
- Bone mineral density less than 2.5 standard deviations or more than the mean of a young adult
- Testing – T score of -2.5
- T score -1 to -2.5 = osteopenia
- Occurrence
- Affects more than 10 million people in the US
- Signal symptoms
- Occur late in disease
- If these signs are present, fractures are present
- Screening is important!
- Kyphosis
- Decreased height
- Vertebral fractures
- Severe back pain
- Signs and Symptoms
- Kyphosis of the spine
- Evidence of oral bone loss
- Restrictive pulmonary problems
- Due to decreased volume of the thoracic cage/chest expansion
- Vertebral fractures
- Swelling, tenderness, and ecchymosis from fracture
- Limited ROM and painful movement
- Protuberant abdomen
- Prevention/prophylaxis
- Focus on prevention at an early age
- Peak bone mass in adolescence
- If there is a failure to produce quality bone in adolescence, effects bone for lifetime
- Diet, exercise
- Avoiding smoking, reducing alcohol intake
- Quality/quantity effects fracture risk
- Reduction of risk factors
- Screening
- Age, gender, ethnicity factors
- Increased risk with age
- Increased rate of bone loss in women after menopause along with increased risk of falling
- Risk twice as great in white women compared w/ African American women
- Men are at risk too
- Risk Factors
- Modifiable
- Medication
- Steroids, lithium, thyroid hormones, chemotherapy, aluminum acids, tetracycline
- Tobacco use
- Alcohol consumption
- Sedentary lifestyle
- Diet
- Calcium & Vit D consumption
- Carbonated beverages are known to contribute to bone loss
- Low BMI
- As much as a 2% weight loss in a man can reduce mineral density
- Non-modifiable
- Age
- Family history
- Female gender
- Small bone structure
- Disease
- HTN, diabetes, RA, CKD, Cushings disease, liver disease, hyperparathyroidism, alcoholism, hx or gastric bypass or organ transplant
- Women who experience early menopause w/o HRT
- Malabsorption problems
- Anorexia
- Medication
- Clinical Screening
- Physical assessment
- Yearly height measurement
- Assess gait
- Assess dentition and bone loss
- FRAX screen
- USPSTF Screening Recommendations
- Women
- 65 or older
- Younger women whose fracture risk is equal to or greater than that of a 65 yr. old white women with no additional risk factors
- Men
- Insufficient evidence to assess the balance of benefits and harms of screening for osteoporosis
- NOF
- Men older than 50 are more likely to break a bone than they are to get prostate cancer
- Other risk factors – NOF guidelines support screening
- Guidelines may conflict, just make sure you’re using EBP
- Diagnostic tests
- BMD measurements
- DEXA
- T scores
- Compares patient’s bone mass to the mean bone mass of a young adult
- T score of -2.5 = osteoporosis
- -1 to -2.5 osteopenia
- Z score
- Compares patient to average person in their age range
- QCT
- Expensive test
- 3 dimensional study
- US of heel
- Inexpensive screen
- Often seen at health fairs
- Lab tests
