Arthritis Of The Fingers types and patterns - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes conditions associated with arthritis of the fingers. Diagnosing arthritis of the finger can is difficult. Arthritis can affect any joint in the body but it is commonly seen in the joints of the fingers. There are different types of arthritis and the pattern of joint involvement: 1- Generalized osteoarthritis: Heberden’s nodes: Heberden's nodes are hard or bony swellings that can develop in the distal interphalangeal joints (DIP) and may or not be painful. Heberden’s nodes are caused by the formation of osteophytes due to repeated trauma at the joint and usually occurs during middle age. Bouchard’s nodes: Bouchard's nodes are bony growths that can form on the proximal interphalangeal joints of the finger (PIP). Bouchard’s nodes, like Heberden’s node, may or may not be painful. Bouchard’s nodes are typically associated with limited motion of the affected joint. Mucous cyst: small, fluid-filled sacs that form between the DIP joint of the finger and the bottom of the fingernail. The best treatment is surgical excision of the cyst and removal of the underlying osteophyte to decrease the risk of recurrence. 2- Psoriasis: it is an inflammatory form of arthritis and sometimes confused with osteoarthritis. Dactylitis is also referred to as “sausage digit”. It is inflammation of the entire digit. Sausage finger is a major finding of psoriatic arthritis. Nail pitting is small depressions in the finger nails and it is most common in people who have psoriasis. 3- Gout: gout is a form of inflammatory arthritis that is sometimes called “gouty arthritis”. Gouty arthritis will mimic infection and may develop in people who have high levels of uric acid in the blood. The uric acid can form needle like crystals in the joint and cause pain, tenderness, swelling and tenosynovitis. Periarticular erosions seen on x-ray may also be present with gout of the finger joints. Periarticular erosions are usually multiple and bilateral with sclerotic borders. 4- Juvenile rheumatoid arthritis: ANA positive in 30%. Rheumatoid factor is negative in a child and later on it may become positive. Shortened digits. Polyarticular rheumatoid arthritis (JRA) is a form of juvenile rheumatoid arthritis that affects five or more joints. Polyarticular in about 30%. Pauciarticular onset juvenile idiopathic arthritis (JIA) is a form of juvenile rheumatoid arthritis that affects less than five joints. Pauciarticular in about 50%. In pauciarticular onset juvenile idiopathic arthritis, check the iris of the eye for iridocyclitis.
