synovial fluid n.
Wounds of tendon sheaths are similar to open joints in that there is an escape of synovial fluid, "sinew water."
This consisted of synovial fluid admixed with a varying proportion of blood.
If the puncture involves the sesamoid sheath, the synovial fluid escapes.
The synovial layer also is torn, and the joint becomes filled with blood and synovial fluid.
An escape of synovial fluid, pain and some swelling will occur even with a very small penetration.
Is this a uric acid condition, or do you think it merely due to a lack of nourishment, causing a lack of synovial fluid?
In some cases of injury and disease, the synovial fluid is secreted in large quantities, and distends the sac of the joint.
