Episode notes
Two Types Of Bone Tissue
- Bone has two main tissues: dense cortical bone and spongy trabecular bone that contains gaps.
- Trabecular bone is concentrated in vertebral bodies, femoral necks, and joint surfaces making those areas more fracture-prone.
What Osteoporosis Means
- Osteoporosis is defined as 20% or more bone loss and mainly affects trabecular bone.
- Loss in these spongy areas greatly increases fracture risk even from minor bumps or falls.
Bones Adapt To Load
- Bone remodeling balances osteoblasts (builders) and osteoclasts (crunchers) and shifts with age.
- Wolff's law means bone strengthens where it experiences load; lack of load leads to resorption.
