Injuries to the Skeletal System

1. Injuries to the Skeletal System

2. Is this weight bearing or non weight bearing? • What is a long term benefit that this type of activity provides to the skeletal system?

3. Lesson Objectives • knowledge of the different sports injuries that can happen to the skeletal system • Knowledge of exercise and the effects it has on the skeletal system • Knowledge of diet and the effects it has on the skeletal system

4. Fractures • Compound • Greenstick • Simple • Stress http://www.youtube.com/watch?v=9QTCBrefXso

5. Fractures • Compound: Broken bone that comes through the skin • Greenstick: Break only part way across the bone • Simple: Fracture in one line, no displacement • Stress: Overuse injuries usually in weight bearing areas such as lower leg (shin splints)

6. Guess the Fracture

7. Joint Injuries • Tennis & Golfers Elbow • Dislocations • Sprains • Torn Cartilage

8. Tennis & Golfers Elbow This is an injury cause by overuse to the tendons at the elbow joint. • Dislocation This is when a bone is forced out of its normal position as a result of a hard impact causing the blood to be displaced. • Sprain This is a damaged ligament, commonly caused by a twisting of the ankle • Torn Cartilage Cartilage is a protective substance that covers the end of a bone. Tearing can be caused by twisting at a joint e.g. the knee

10. Treatment - RICE • Rest • Ice • Compression • Elevation

11. Test your knowledge • What type of injury is a dislocation? (1) • What is the cause of tennis elbow? (1) • Which physical activity would you choose if you wanted to improve your bone strength(1) cycling swimming running • Explain why you chose the activity. (3)
