Disorders of the Skeletal System

1. Disorders of the Skeletal System • Osteoporosis • Discuss this condition. • Oste/o por/ous osis • What household object does osteoporosis remind you of? 1.03 Understand the functions and disorders of the skeletal system

2. Disorders of the Skeletal System • Osteoporosis • 80% of those affected are women, mineral density of bone is reduced 35%-65%. The loss of bone mass leaves the bone thinner, porous and more prone to fracture. 1.03 Understand the functions and disorders of the skeletal system

3. Disorders of the Skeletal System • Osteoporosis • Prevented by dietary calcium. 1.03 Understand the functions and disorders of the skeletal system

4. Disorders of the Skeletal System Sprain A sudden or unusual motion ligaments torn but joint not dislocated. Treatment: RICE Rest, Ice, Compression, Elevation 1.03 Understand the functions and disorders of the skeletal system

5. Abnormal Curvature of the spine

6. Disorders of the Skeletal System • Trauma • Dislocation: bone displaced from proper position in joint • Fractures: Break in bones 1.03 Understand the functions and disorders of the skeletal system

7. Skeletal System Trauma • Dislocation • What are the characteristics of a dislocation? • Compare dislocation to subluxation. 1.03 Understand the functions and disorders of the skeletal system

8. Skeletal System Trauma • Trauma • FracturesClosed –simple bone broken, broken ends do not break the skin 1.03 Understand the functions and disorders of the skeletal system

9. Skeletal System Trauma • Trauma • Treatment: closed reduction, cast, or splint applied. 1.03 Understand the functions and disorders of the skeletal system

10. Skeletal System Trauma • Traction • A pulling force used to hold the bones in place used for Fracture of long bones. 1.03 Understand the functions and disorders of the skeletal system

11. Skeletal System Trauma • Fractures • Open or compound • Broken bones pierce the skin and can lead to infection. • Treatment: open reduction surgical intervention with devices such as wires, metal plates, or screws to hold the bones in alignment. 1.03 Understand the functions and disorders of the skeletal system

12. Skeletal System Trauma • Fractures • Comminuted splintered or broken into many pieces. • Treatment: cast, possible surgery, depending how bad the break is. 1.03 Understand the functions and disorders of the skeletal system

13. Skeletal System Trauma • Fractures • Greenstick: In children, bone bent and splintered but never completely separates. 1.03 Understand the functions and disorders of the skeletal system

14. Skeletal System Trauma • Fractures fracture sites related to osteoporosis Explain why fractures are common in these sites. 1.03 Understand the functions and disorders of the skeletal system

15. 1.03 Understand the functions and disorders of the skeletal system Essential Standards: • What are the functions of the skeletal system? • What are some disorders of the skeletal system? • How are skeletal disorders treated? • How does the skeletal system relate to the body’s systems of support and movement? 1.03 Understand the functions and disorders of the skeletal system
