Bone and Joint Disorders Flashcards
What is osteoporosis?
A common bone disorder that is caused by low bone density and a deterioration of bone tissue. The bone weakens and is prone to fractures.
What types of sport are not good for people with osteoporosis?
Contact or impact sports
What type of people are prone to getting osteoporosis?
Any age or gender can be affected by it
What is the best defense against osteoporosis?
Physical activity and a healthy diet as they build strong and healthy bones
What helps to minimise the risk of getting the risk of osteoporosis in later life?
High peak bone density
How can high impact activity have a positive effect during early life?
It helps to increase peak bone density so it helps the bones to develop as strong healthy bones
What is growth plate?
It is the delicate area found between the shaft and either end of the long bone in children and adolescents. When the growth plate completely closes it is replaced by solid bone.
When is injury to the growth plate more common?
In young people because it is the weakest area of the growing skeleton
What types of activities are most likely to cause injuries to the growth plate?
Competitive, impact, competitive and repetitive sports
What type of disorder is osteoporosis?
Bone disorder
What type of disorder is growth plate?
Bone disorder
What type of disorder is osteoarthritis?
Joint disorder
What type of disorder is joint stability?
Joint disorder
What is osteoarthritis?
A joint disease caused by the loss of articular cartilage at the end of the long bone joints, which causes swelling, pain and reduces motion
What does the articular cartilage do?
It absorbs shock, releases synovial fluid and prevents friction between the bone
What effect can repetitive physical activity have on joints in gaining osteoarthritis?
They can cause wear and tear on the articular cartilage which causes joint pain and swelling
What risk factors are there of getting osteoarthritis?
A major injury to a joint and being overweight
What effect will the risk factors have on the joint?
They will cause excessive mechanical strain and will contribute to wear and tear of the articular cartilage
What activities are closely linked with getting osteoarthritis?
Physical activity that involves large and abrupt forces
How can physical activity have a positive effect on osteoarthritis?
If the frequency, intensity and duration is carefully managed
What effect will losing weight have on the chance of getting osteoarthritis?
It will decrease the chance as less weight pushing on the joints will reduce mechanical strain
How can regular activity improve joint stability?
By strengthening the muscles and joints and to maintain joint mobility
What is joint stability?
How stable the joint is
Why is joint stability an important factor of lifelong involvement in physical activity?
A stable joint can be constantly stretched and compressed without injury
