Metabolic Disorders typically relate to bone reabsorption rate and include what?
- Osteoporosis
- Osteomalcia
- Paget Disease
Osteoblast is responsible for what ?
Responsible for new bone formation
Osteoclast is responsible for?
Responsible for old bone reabsorption
What are the types of bone ?
Trabecular or Cancellous – which are a Spongy Inner Bone
What is the outer hard bone called ?
Cortical
What is softening of the bone called?
Osteomalacia
When you have low bone mass what is this called ?
Osteopenia
When you have decreased bone density what is this called?
Osteoporosis
What is the Most common Metabolic Bone Disease affecting at least 10 million Americans
Osteoporosis
Who is affected by osteoporosis ?
women who are post-menopausal
and estrogen deficient
24% of women over the age of 50 years die from
complications within 1 year after an osteoporotic
related hip fracture
Affects 2 million men
What are some nonmodifiable risk factors for osteoporosis ?
Age >50
Caucasian/Asian
Northern European
Family History of Osteoporosis
Long periods inactivity, immobilization, long term care
Depression
What are some modifiable risk factors for osteoporosis?
Physical activity
Alcohol use
Tobacco use
Diet and nutrition
Corticosteroids use
Do actions when you are young affect bone older in life?

Signs and symptoms for osteoporosis are .
Height loss
Posture
Back pain
Possible fracture
3 tests for osteoporosis are ?
Bone mineral density test
Z score
T score
What are some treatments for osteoporosis :

Reducing alcohol intake
Nutritional components
Physical activity and exercise
Calcium, Vitamin D and diet important factors
Estrogen (post-menopausal women) and Biophosphates useful medications
Orthopedic intervention as needed
What is osteomalacia ?
Progressive disease lacks mineralization of bone which results in softening of bones
Stems from insufficient Vitamin D, Calcium or phosphate
Patients with osteomalcia are at increased risk for Osteoporosis, is this true or false.
True
What are some treatment considerations for osteomalacia:
We must address nutrition and/or absorption
Patient education similar to osteoporosis
weight bearing exercises should be beneficial
What is paget disease?
Also know as osteitis deformans
This is the 2nd most common metabolic disease!!!
Considered a Progressive disorder of the skeletal system
Increased bone resorption by osteoclasts and excessive, unorganized new bone formation by osteoblasts.
What happens during Paget’s disease?
Initially abnormal osteoclasts proliferate at increased rate
Rapid resorption doesn’t allow the osteoblastic activity to keep up so the fibrous tissue replaces bone
Within the later phases, instead of normal cancellous bone there is coarse, thickened struts of trabecular bone, and the cortical bone is irregularly thickened, rough, and pitted.
After the later phases the bone is now heavily calcified and enlarged but weakened with a chaotic woven pattern!!
What is the diagnosis for Paget’s disease?
It is usually based on the characteristic bone deformities and radiologic bony changes
A screen test measures alkaline phosphate levels which are normally high in this disease
What are some treatment considerations for Paget’s disease?
Bisphosphates
NSAIDs to control pain
Surgery to repair fractures
exercise!!
How come we have to be aware of metabolic bone conditions in our patients ?
Manual therapy
Patient education
Fall prevention
AND screening patients who are undiagnosed
Important for prescribing types of exercises
