Erosive osteoarthritis is a more severe variant of osteoarthritis (a degenerative arthritic condition in which cartilage and bones atrophy in the joints) in which the withering of bone and cartilage in the joints simultaneously occurs with inflammation (commonly associated with infection).  Erosive osteoarthritis frequently afflicts the hands of patients and is believed to be inherited, accelerated by diseases and infections commonly attributed to the joints in the hands. 

The most common form of arthritis, osteoarthritis is generally attributed to sustained wear and tear on bones, cartilage and joints.  Erosive arthritis progresses faster than traditional osteoarthritis, with total joint destruction often occurring with one to two years. 

Erosive Osteoarthritis vs. Osteoarthritis
Ordinary osteoarthritis can cause the formation of bone spurs, which can lead to further problems and pain during high-movement activities (like running or golf).  Erosive osteoarthritis, on the other hand, causes similar erosion of the bones simultaneously with inflammation that progress independent of a patient’s daily activities.  It affects primarily the middle and end finger joints, the joint at the base of the thumb, and causes redness, swelling and pain of the joints. 

Hand deformity and impaired hand function are definite concerns with erosive osteoarthritis.  Some of the worst instances, and some of the most gruesome physical examples of arthritis, are often resulting from severe cases of erosive osteoarthritis.

Occasionally, erosive osteoarthritis may develop into rheumatoid arthritis.  If one experience significant worsening of symptoms, especially if increased pain and morning stiffness are presenting in the knuckles or wrist, then a physician should be consulted.
