From our day to day experience you might have learnt many problems associated with skeletal system. Some times during a cricket match the muscle of a fast bowler gets pulled, joint of a wrestler may get dislocated, bones of a person may be fractured in an accident and so on. Although bones are the hardest parts of our body but sometimes our skeletal system becomes weak and results in deformations. Some of these disorders are described here briefly.

1.Osteoporosis:

As you have studied bones are formed by the process of mineralization. Calcium phosphate is deposited on collagen fibers to make the bones. This calcium is taken with the food. From gastro-intestinal wall it is absorbed into the blood. From blood this calcium reaches the bones. The blood Calcium level is 30mg/100ml.

When person is not taking sufficient calcium in daily diet his bones start becoming weak. In this disease the bones become fragile and prone to fracture. Calcium start breaking up from the bones to maintain its level in the blood, a process called demineralization. If this situation prolongs the bones become soft and fragile and start bending and can easily be broken. This disorder is known as osteoporosis. This disorder is very common in females.

The leading cause of osteoporosis is a lack of certain hormone, particularly estrogen in women and androgen in men. Women especially those older than 60 years of age, are frequently diagnosed with the disease.

2.Arthritis:

Arthritis is the inflammation of the joints. It can affect one joint or multiple joints. The symptom of arthritis usually develops over time. This is a degenerative disease that damages joints permanently. As a results pain, stiffness and swelling of the joints takes place. Secondary bacterial infection causes acute pain which is usually treated with antibiotics. Cartilage is a firm but flexible connective tissue in our joints. A reduction in the normal amount of this cartilage tissue cause some forms of arthritis. In this disorder membranes lining the joints thickens, fluid production is decreased, which results in increased friction casing severe pain and in the later stages complete immobility. With the passage of time the joints become permanently swollen and get de-shaped.

Generally the patient feels more pain in winter. Different types of chronic arthritis are osteoarthritis, rheumatoid arthritis, and gouty arthritis.

Osteoarthritis:

It is the most common type of arthritis, which occurs most often in older people. This disease affects cartilage which starts to wear away over time. In extreme cases, the cartilage can completely wear away, leaving nothing to protect the bones in a joint, causing bone-0n-bone contact. It causes joint pain and can limit a person’s normal range of motion. When severe, the joint may lose all movement, causing a person to become disabled.

Rheumatoid Arthritis.

This is an auto-immune disease in which the body’s immune system attacks healthy joints, tissues, and organs. It can cause pain, stiffness, swelling, and loss of function in joints. When severe, rheumatoid Arthritis can deform, or change, a joint.

Gouty Arthritis:

When a person has gout, they have higher than normal levels of uric acid in the blood. The body makes uric acid in the blood the body makes uric acid from many of the foods we eat. Too much uric acid causes deposits, called uric acid crystals, to form in the fluid and lining of the joints. The result is an extremely painful attack of arthritis.
