Crystal arthropathies are a group of joint disorders due to deposition of crystals in and around joints which lead to joint destruction and soft tissue disturbances (swelling, redness, masses etc.). Clinical presentations of the different types of crystal arthropathies are often characteristic enough to differentiate them from each other, but mistakes can be made, leading to delayed or incorrect management. Gout is the most common form of crystal arthropathies. First identified by the Egyptians in 2640 BC and later by Hippocrates in the 5th century BC, who referred to as “the unwalkable disease”. Throughout history, gout has been associated with rich foods and excessive alcohol consumption and has been referred to as the “disease of kings”. Calcium pyrophosphate dihydrate disease (CPPD/pseudogout) and basic calcium phosphate (BCP/hydroxyapatite) are the two other forms of crystal arthropathies.
