Q

Describe the pathophysiology of RA

A

The body attacks the synovium in the joints and causes inflammation so fluid and inflammatory cells build up around the joint. The fluid stretches the joint capsule so the joint becomes unstable and over time the joint space is worn away due to repeat inflammation

Q

Describe the pathophysiology of osteoarthritis

A

The cartilage on the bone surface wears away with use and becomes rough. The underlying bone becomes thicker and grows outwards creating osteophytes. The synovium thickens and produces extra fluid which causes the joints to swell. The capsule and ligaments around the joint thicken and shorten to try and stabilise the joint but this causes joint stiffness.

1st MTP (big toe)
55
Which joint is commonly most affected in pseudogout?

56
What is osteoporosis?
Osteoporosis is when the spongy trabecular network in bone becomes less dense and so the bones become very fragile and more likely to fracture
57
How does osteoporosis normally present?

60
How can osteoporosis be diagnosed?
DEXA scan (measures density of bones)
61
What is the FRAX tool?
Tool used to decide who needs a DEXA scan and to predict future risk of having a fracture
