Estrogen (post-menopausal women) and Biophosphates useful medications
Orthopedic intervention as needed
162
What is osteomalacia ?

163

True
164
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
165
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.
166
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!!
167
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
168
What are some treatment considerations for Paget’s disease?
Bisphosphates
NSAIDs to control pain
Surgery to repair fractures
exercise!!
169
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
