 Arthritis is a form of arthropathy that involves inflammation of one or more joints,while the term arthropathy may be used regardless of whether there is inflammation or not.
Arthropathy may also include joint conditions caused by physical trauma to joints, but is traditionally used to describe the following conditions:
Reactive arthropathy is caused by an infection, but not a direct infection of the synovial space.
Enteropathic arthropathy is caused by colitis and related conditions.
Chondrocalcific Arthropathy progressive polyarthritis with joint swelling and bony enlargement, most commonly in the small joints of the hand but also affecting other joints, characterized radiographically by narrowing of the joint space with subchondral erosions and sclerosis and frequently chondrocalcinosis.
Crystal arthropathy (also known as crystal arthritis) involves the deposition of crystals in the joint.
1) In gout, the crystal is uric acid.
2) In pseudogout/chondrocalcinosis/calcium pyrophosphate deposition disease, the crystal is calcium pyrophosphate
Diabetic Arthropathy is caused by diabetes.
Osteopulmonary Arthropathy clubbing of fingers and toes, and enlargement of ends of the long bones, in cardiac or pulmonary disease.
Neuropathic Arthropathy chronic progressive degeneration of the stress-bearing portion of a joint, with hypertrophic changes at the periphery; it is associated with neurologic disorders involving loss of sensation in the joint. Called also Charcot's arthropathy.
