Heberden's nodes are hard or bony swellings that can develop in the distal interphalangeal joints (DIP) (the joints closest to the end of the fingers and toes). [1] They are a sign of osteoarthritis and are caused by formation of osteophytes (calcific spurs) of the articular (joint) cartilage in response to repeated trauma at the joint.
Hypertrophic osteoarthropathy is a medical condition combining clubbing and periostitis of the small hand joints, especially the distal interphalangeal joints and the metacarpophalangeal joints. Distal expansion of the long bones as well as painful, swollen joints [3] and synovial villous proliferation are often seen.
Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
Happens with symptoms like mild swelling, redness, and warmth. Joint pain can be a sign of a medical emergency if it: Is severe. Comes on after an injury. Affects your ability to use the joint.
In smaller joints, such as at the fingers, hard bony enlargements, called Heberden's nodes (on the distal interphalangeal joints) or Bouchard's nodes (on the proximal interphalangeal joints), may form, and though they are not necessarily painful, they do limit the movement of the fingers significantly.
Involvement of the distal interphalangeal joints is a characteristic feature present in many cases. [6] Enthesitis pain can spread over a wider area around the joint. [7] In addition to affecting the joints of the hands and wrists, psoriatic arthritis may affect the fingers, nails, and skin.
DAS28: Disease Activity Score of 28 joints (DAS28) is widely used as an indicator of RA disease activity and response to treatment. Joints included are (bilaterally): proximal interphalangeal joints (10 joints), metacarpophalangeal joints (10), wrists (2), elbows (2), shoulders (2) and knees (2). When looking at these joints, both the number of ...
Trauma deformities may manifest as reduced joint function due to lack of coordination in phalangeal joints, such as proximal interphalangeal flexion and distal interphalangeal hyperextension in boutonnière deformity. [1] Besides trauma, another reason boutonnière deformity may develop is due to a chronic disease like rheumatoid arthritis. [1]
