Osteoporosis
• Condition: makes your bones weak
• Leaves it more likely to break.
• Anyone can develop osteoporosis.
• Most common in older women.
• As many as half of all women and a
quarter of men older than 50 will break a
bone due to osteoporosis.

Risk factors
• Getting older
• Being small and thin
• Having a family history of osteoporosis
• Taking certain medicines
• Being a White or Asian woman
• Having osteopenia, which is low bone
mass

Extra information
• Osteoporosis is a silent disease.
• Might not know until a bone is broken
• A bone mineral density test is the best way
to check the bone health.
• To keep bones strong, eat a diet rich in
calcium and vitamin D, exercise and do
not smoke. If needed, medicines can also
help.

Osteogenesis Imperfecta
• Also called: Brittle bone disease, OI
• Osteogenesis imperfecta (OI) is a genetic disorder in which bones break easily.
• Sometimes the bones break for no known reason.
• OI can also cause weak muscles, brittle teeth, a curved spine and hearing loss.
• The cause is a gene defect that affects how you make collagen, a protein that helps make bones strong.
• When a patient inherits the faulty gene from a parent.
• Sometimes, it is due to a mutation, a random gene change.

Extra information
• OI can range from mild to severe and symptoms vary from person to person.
• A person may have just a few or as many as several hundred fractures in a lifetime. There is no cure, but you can manage symptoms.
• Treatments include exercise, pain medicine, physical therapy, wheelchairs, braces and surgery.

Paget’s disease
• Also called: Osteitis deformans
• Paget's disease of bone causes bones to grow larger and weaker than normal.
• They also might break easily. The disease can lead to other health problems, too, such as arthritis and hearing loss.
• A patient can have Paget's disease in any bone, but it is most common in the spine, pelvis, skull and legs.
• The disease might affect one or several bones, but not the entire skeleton.
• More men than women have the disease.
• It is most common in older people.

More information
Many people do not know they have Paget's disease because their symptoms are mild. For others, symptoms can include
• Pain
• Enlarged bones
• Broken bones
• Damaged cartilage in joints
• No one knows what causes Paget's disease.
• In some cases, a virus might be responsible. It tends to run in families. Treatment includes medication and sometimes surgery. A good diet and exercise might also help.

Information on Rheumatoid Arthritis
• Rheumatoid arthritis is an autoimmune disease
in which the body's immune system attacks
itself.
• The pattern of joints affected is usually
symmetrical, involves the hands and other joints
and is worse in the morning.
• Rheumatoid arthritis is also a systemic disease,
involving other body organs, whereas
osteoarthritis is limited to the joints.
• Over time, both forms of arthritis can be
crippling.

Severe rheumatoid arthritis
![Page 14: Diseases pertaining to the skeletal system - … · Diseases pertaining to the skeletal system . Osteoporosis ... bone due to osteoporosis. ... • There are three types of bone cancer:](https://reader031.vdocuments.net/reader031/viewer/2022022016/5b7291b27f8b9a0c418cc530/html5/thumbnails/14.jpg)
How it happens
• Deformities distinctive to late-stage
rheumatoid arthritis such as ulnar
deviation of the bones of the hands occur
because muscles and tendons on one side
of the joint may overpower those on the
other side, pulling the bones out of
alignment.

More information
• The cause of RA is unknown.
• It is considered autoimmune disease.
• The body's immune system normally fights off
foreign substances, like viruses. But in an
autoimmune disease, the immune system
confuses healthy tissue for foreign substances.
As a result, the body attacks itself.
• RA can occur at any age. Women are affected
more often than men.

Location
• RA usually affects joints on both sides of
the body equally.
• Wrists, fingers, knees, feet, and ankles are
the most commonly affected.
• The course and the severity of the illness
can vary considerably.
• Infection, genes, and hormones may
contribute to the disease.

Carpal tunnel syndrome
• It may result from repetitive motion or the
use of devices like computer keyboards.
• It affects the median nerve, the nerve that
supplies feeling and movement to the
thumb and "thumb-side" of the hand.

Bone cancer
• Cancer that starts in a bone is rare.
• Cancer that has spread to the bone from another part of the body is more common.
• There are three types of bone cancer:
• Osteosarcoma - develops in growing bones, usually between ages 10 and 25
• Chondrosarcoma - starts in cartilage, usually after age 50
• Ewing's sarcoma - begins in nerve tissue in bone marrow of young people, often after treatment of another condition with radiation or chemotherapy

Symptoms
• The most common symptom of bone
cancer is pain.
• Other symptoms may vary depending on
the location and size of the cancer.
Surgery is often the main treatment for
bone cancer.
• Other treatments may include amputation,
chemotherapy and radiation.
