Question

Synovial fluid was sampled for a joint condition and rhomboid shaped crystals with weak positive birefringence under polarised light were found. What joint disease is this an indicator of? (1 Marks)
A) Pseudogout
B) Gout
C) Rheumatoid arthritis
D) Osteoarthritis

Answer 1

Synovial fluid analysis will reveal rhomboid crystals with weak positive birefringence under polarized light compared to gout for which there are needle-shaped crystals with negative birefringence under polarised light (yellow when parallel) in synovial fluid.

Answer 2

Rheumatoid arthristis.
This is an auto immune disease in which amount of synovial fluid increases and die to increased pressure these clump and forms hard pannus particles/crystals , which causes intense pain in joints.
This can be treated by heat therapy by melting down pannus crystals
Hope this helps you
Thankyou
