This lesson will give an overview of disorders of the skeletal system by looking at:
There are various disorders that affect the skeletal system. These disorders have many different causes, such as aging, overuse, lifestyle, et cetera. Here we'll discus several common disorders and their causes.
Osteoporosis is a loss of bone mass, or deterioration of bone over time. The main cause of osteoporosis is aging. Deficiencies in calcium can also contribute to this disorder. If you have a diet that is lacking in calcium, bones aren't able to stay as strong and resilient as they otherwise would, losing mass over time. A sedentary lifestyle also contributes to osteoporosis. This disorder is actually most common in women who are past menopause.
Osteoarthritisis a disorder where the cartilage between the joints starts to wear away. The main causes are stress on the joints, disease, sports injury, obesity, and age. Osteoarthritis can be very painful because it causes the ends of the bones to rub against each other.
Carpal Tunnel Syndrome
Carpal tunnel syndrome occurs when the tendons of the wrist swell and press on nerves, causing pain. Carpal tunnel syndrome is common in people who work on computers because it's a repetitive motion, such as typing, that causes stress on the tendons of the wrist.
Sprains, Strains, and Dislocations
These are all disorders that are caused by injury of the joints. A sprain is a tear in a ligament or tendon; a strain is when a ligament or tendon has been stretched or twisted too far; and a dislocation is when two bones at a joint are no longer in contact. Common causes of these types of disorders are sports injuries, overuse, and mechanical stress.
Breaks are another common disorder of the skeletal system, and there is a spectrum used to classify the degree of the break. These classifications include a simple, complete, or compound fracture. Breaks are caused by sports injuries, overuse, and mechanical stress.
Let's take a look at the different types of breaks.
A simple fracture is a small fracture in a bone. It doesn't go through the entire bone, and there isn't any surrounding tissue damage.
A complete fracture occurs when the bone actually breaks into two pieces. There will be some soft tissue damage associated with this type of break.
A compound fracture is the worst type of break. Rather than cleanly breaking, as in a complete break, bone fragments have actually shattered. In this type of break, broken ends of the bone will generally puncture the skin, and other soft tissue damage will occur.
This has been an overview on common disorders of the skeletal system, though it is not a complete list. While aging, diet, lack of exercise, injury, and overuse contribute to the disorders we covered in this lesson, other disorders, such as cancer, can also have an effect on the skeletal system. When we break a bone, there are three classifications of breaks the injury can fall into, with simple fractures being the least complex, and compound fractures being the most complex and serious.
Keep up the learning and have a great day!

The inflammation of tendons in the wrist which then press on surrounding nerves caused by repeated motion.
A break in which the bone shatters causing a significant amount of soft tissue damage.
A disorder in which two bones of a joint are no longer in contact with each other.
The wearing away of cartilage that occurs between joints which can lead to inflammation and the formation of small protrusions on bones near the joint called bone spurs.
A disorder in which the bone tissue deteriorates over time.
A break in which the bone is still in one piece and minimal or no tissue damage occurs.
A torn ligament or tendon caused by overuse.
A break in which the bone separates into two and tissue damage occurs.
An overuse injury that stretches a tendon past its normal point.
