What joints does psoriatic arthritis attack
What joints does psoriatic arthritis attack Psoriatic arthritis is a chronic autoimmune condition that affects some individuals with psoriasis, a skin disorder characterized by red, scaly patches. Unlike standard forms of arthritis, which typically target specific joints, psoriatic arthritis can involve a wide range of joints throughout the body, leading to pain, stiffness, swelling, and potential joint damage if not managed effectively. Understanding which joints are commonly affected can help in early diagnosis and targeted treatment.
What joints does psoriatic arthritis attack The joints most frequently attacked by psoriatic arthritis are those of the fingers and toes. This includes the distal interphalangeal (DIP) joints, which are the small joints closest to the tips of the fingers and toes. Involvement of these joints is quite characteristic of psoriatic arthritis and can lead to a distinctive pitting and ridging of the nails. Swelling in these joints often resembles a sausage, a condition known as dactylitis, which is a hallmark feature of psoriatic arthritis.
Beyond the fingers and toes, psoriatic arthritis commonly affects larger joints such as the knees, ankles, and wrists. These joints can become swollen, tender, and stiff, particularly in the morning or after periods of inactivity. The inflammation can impair mobility and may lead to joint erosion if left untreated. The pattern of joint involvement can vary, with some patients experiencing symmetrical joint swelling similar to rheumatoid arthritis, while others have asymmetric patterns.
What joints does psoriatic arthritis attack In addition to peripheral joints, psoriatic arthritis can also involve the axial skeleton, which includes the spine and sacroiliac joints—the joints connecting the lower spine to the pelvis. Spinal involvement can cause back pain, stiffness, and reduced range of motion. This axial arthritis often presents differently from other forms of spondyloarthritis, with inflammation sometimes affecting the entire spine or specific regions.
What joints does psoriatic arthritis attack The involvement of the sacroiliac joints is particularly significant because it can mimic other conditions like ankylosing spondylitis. In psoriatic arthritis, sacroiliitis (inflammation of these joints) can cause pain that radiates to the buttocks and thighs, often worsening with rest and improving with activity. This axial involvement may be present alongside peripheral joint symptoms or as the predominant feature.
What joints does psoriatic arthritis attack Less commonly, psoriatic arthritis can involve the hips, shoulders, elbows, and even the small joints of the hands. The severity and pattern of joint involvement vary among individuals, with some experiencing only mild symptoms and others facing progressive joint damage.
Early diagnosis and intervention are crucial in managing psoriatic arthritis because timely treatment can prevent joint destruction and improve quality of life. Treatment strategies typically include anti-inflammatory medications, disease-modifying antirheumatic drugs (DMARDs), and biologic agents that target specific aspects of the immune response.

In summary, psoriatic arthritis can target a wide array of joints, including the distal and proximal joints of the fingers and toes, knees, ankles, wrists, and the axial skeleton involving the spine and sacroiliac joints. Recognizing the pattern of joint involvement helps healthcare providers diagnose the condition accurately and tailor effective treatment plans.
