Care of Patients with Musculoskeletal Patients Flashcards
Osteoporosis:
chronic metabolic disease in which bone loss causes decreased density and possible fracture
Bone is a dynamic tissue that is constantly undergoing changes in a process called
bone remodeling
Osteoporosis and osteopenia (low bone mass) occur when
Osteoclastic (bone reabsorption) activity is greater than osteoblastic (bone building) activity
The result is a decreased bone mineral density (BMD): determines bone strength and peals between 25-30 years of age
A T-score represents the
number of standard deviations above or below the average BMD for young, healthy adults
Osteopenia is present when the T score is at
-1 and above -2.5
Osteoporosis is diagnosed when the T score is
at or lower than -2.5
Medicare reimburses for BMD testing every 2 yr in people ages of 65 and older who are:
Estrogen deficient Have vertebral abnormalities Receive long term steroid therapy Have primary hyperparathyroidism Being monitored while on osteoporosis therapy
Generalized osteoporosis involves many structures in the skeleton and is further divided into 2 categories:
Primary: occurs in postmenopausal women and in men in their seventh or eighth decade of life
Secondary: result from other medical conditions, such as hyperparathyroidism; long term drug therapy, such as with corticosteroids; or prolonged immobility, such as seen w/ spinal cord injury
Excessive ______ in the diet can cause calcium loss in the urine
caffeine
What can also reduce bone density?
Protein deficiency
Yet, excessive protein intake may increase calcium loss in the urine
Other risk factors of Osteoporosis:
Excessive alcohol and tobacco use
Kyphosis:
curvature of the thoracic spine, “dowager’s hump”
-2-3 in shorter w/in previous 20 years
The most common type of osteoporotic fracture:
back pain accompanied by tenderness and voluntary restriction of spinal movement suggests one or more compression vertebral fractures
Quality of life might also be impacted by
pain, insomnia, depression, and fallophobia (fear of falling)
Lab assessments:
biochemical markers Bone specific alkaline phosphate (BSAP) Osteocalcin N-telopeptide (NTX) C-telopeptide (CTX)
Imaging assessments:
Most common: Dual x-ray absorptiometry (DXA or DEXA)
- painless scan that emits less radiation than a chest x-ray
- best tool
Peripheral quantitative ultrasound (pQUS) is an effective and low cost tool that can detect osteoporosis and predict risk for hip fracture
