2. Lesson 2 How might poor health of your skeletal system affect your overall health? Care and Problems of the Skeletal System

3. Lesson 2 If your skeletal system cannot perform its functions properly, your freedom of movement may be limited and other areas of your health and lifestyle may also be affected. Care and Problems of the Skeletal System

4. Lesson 2 Examine health promotion and prevention of bone disorders Describe types of bone and joint injuries and strategies to prevent injuries that damage the skeletal system In this lesson, you will learn to: Lesson Objectives

5. Lesson 2 Care of the Skeletal System Tips for Healthy Bones and Joints Foods that contain calcium, vitamin D, and phosphorus help prevent certain skeletal disorders. Wearing protective gear when you participate in sporting or recreational activities reduces the risk of bone fractures. Regular physical activity helps keep bones strong.

6. Lesson 2 Fractures Fractures can be either compound or simple. A compound fracture is one in which the broken end of the bone protrudes through the skin. A simple fracture is one in which the broken bone does not protrude. Problems of the Skeletal System

7. Lesson 2 Classification of Fractures Hairline fracture: The fracture is incomplete, and the two parts of the bone do not separate. Transverse fracture: The fracture is completely across the bone. Comminuted fracture: The bone shatters into more than two pieces, usually as a result of severe force. Problems of the Skeletal System

8. Lesson 2 Osteoporosis makes bones weak and brittle.Osteoporosis Regular physical activity stimulates bone cells to increase bone mass, thereby reducing the risk of osteoporosis. Early detection is essential to treatment and to slowing loss of bone tissue. Osteoporosis Problems of the Skeletal System

9. Lesson 2 Scoliosis may exist at the time of birth, or it can develop during childhood.Scoliosis The curvature of the spine worsens as growth continues and may proceed even after growth stops. Treatment includes wearing a brace to help straighten the spine and, in more severe cases, surgery. Scoliosis Problems of the Skeletal System

10. Lesson 2 Typical Joint Injuries Dislocation Torn CartilageBursitis Bunion Arthritis Problems of the Skeletal System

11. Lesson 2 Dislocation Dislocation results when the ligaments that attach the bone at the joint are torn as the bone slips out of place. Never attempt to replace a dislocated joint; get immediate medical help. Treatment includes having the joint reset and immobilized while the ligaments heal. Problems of the Skeletal System

12. Lesson 2 Torn Cartilage Torn cartilage can result from a sharp blow or the twisting of a joint. Injuries are treated with arthroscopic surgery. Problems of the Skeletal System

13. Lesson 2 Bursitis Bursitis results from the inflammation of a fluid-filled sac called the bursa. Certain joints have bursae that help reduce friction between their movable parts. When the bursa becomes inflamed, pain and swelling can occur at the joint. Problems of the Skeletal System

14. Lesson 2 Bunion A bunion is a painful swelling of the bursa in the first joint of the big toe. Large bunions may require surgery. Problems of the Skeletal System

15. Lesson 2 Arthritis Arthritis is the inflammation of a joint. The condition can result from an injury, natural wear and tear, or autoimmune disease. Problems of the Skeletal System

16. Lesson 2 Repetitive Motion Injury One of the most common repetitive motion injuries is carpal tunnel syndrome.repetitive motion injuries This condition occurs when swollen ligaments and tendons in the wrist cause numbness, a burning or tingling sensation in the thumb and forefinger, pain, and weakness in the hand. Treatment includes wearing a splint to reduce wrist movements, medication to reduce swelling and, in a small percentage of cases, surgery. Problems of the Skeletal System

17. Lesson 2 Quick Review Q. Which behavior helps keep your skeletal system healthy? 1.Eating foods that contain calcium, vitamin D and phosphorous 2.Getting regular physical activity 3.Wearing protective gear when you participate in sports 4.All of the above

25. Lesson 2 Scoliosis may exist at the time of birth, or it can develop during childhood.Scoliosis The curvature of the spine worsens as growth continues and may proceed even after growth stops. Treatment includes wearing a brace to help straighten the spine and, in more severe cases, surgery. Scoliosis Scoliosis is a lateral, or side- to-side, curvature of the spine.

26. Lesson 2 One of the most common repetitive motion injuries is carpal tunnel syndrome.repetitive motion injuries This condition occurs when swollen ligaments and tendons in the wrist cause numbness, a burning or tingling sensation in the thumb and forefinger, pain, and weakness in the hand. Treatment includes wearing a splint to reduce wrist movements, medication to reduce swelling and, in a small percentage of cases, surgery. Repetitive Motion Injury Repetitive motion injury is the damage to tissues caused by prolonged, repeated movements. Problems of the Skeletal System
