Study Notes
Modes of Failure
- Manufacturing errors: Disorders of formation and growth, impacting primarily pediatric patients.
- Constant random failures: Primarily due to trauma, infection, cancer, or other acute diseases.
- Wearout failures: Progressive wear of parts, leading to conditions like osteoporosis, osteoarthritis, and rheumatoid arthritis.
Bone Structure
- Diaphysis: Acts as a lever for increased muscle power; characterized by thick cortices.
- Metaphysis and Epiphysis: Have reduced bending force, resulting in thinner cortices and spongy trabecular bone; support articular surfaces, absorb impact, and distribute weight evenly.
