Lesson 2

How might poor health of your skeletal system affect your overall health?

Care and Problems of the Skeletal System

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

Lesson 2

Examine strategies to prevent injuries that damage the skeletal system.

Analyze the relationship between health promotion and prevention of bone disorders.

Identify different types of joint injuries and situations requiring professional health services.

In this lesson, you’ll learn to:

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.

Lesson 2

Fractures

Fractures can be either compound or simple.

A compound fracture is one in which the broken end of thebone protrudes through the skin.

A simple fracture is one in which the broken bone does not protrude.

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.

Lesson 2

Osteoporosis makes bones weak and brittle.

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.

Scoliosis

Scoliosis may exist at the time of birth, or it can develop during childhood.

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.

Typical Joint Injuries

Dislocation

Torn Cartilage

Bursitis

Bunion

Arthritis

Problems of the Skeletal System

Lesson 2

Dislocation

Dislocation results when the ligaments that attach the boneat 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 immobilizedwhile the ligaments heal.

Problems of the Skeletal System

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

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

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.

Lesson 2

Arthritis

Arthritis is the inflammation of a joint.

The condition can result from an injury, natural wear and tear, or autoimmune disease.

Lesson 2

Repetitive Motion Injury

One of the most common repetitive motion injuries is carpal tunnel syndrome.

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.
