1. explain the common radiographic presentation of reactive arthritis and provide examples of triggers that can lead to its development.
2. discuss the importance of early diagnosis and treatment in the management of inflammatory arthritis.
3. describe the imaging modalities commonly used for assessment of joint damage and inflammation in inflammatory arthritis.
4. describe the characteristic joint deformities seen in advanced stages of rheumatoid arthritis and

Explanation:

1. Psoriatic arthritis can have skin - related (psoriasis), nail changes, eye inflammation (uveitis), bowel manifestations, and dactylitis as extra - articular features.
2. Reactive arthritis radiographically shows enthesitis, sacroiliitis, and joint space narrowing. Triggers include gastrointestinal or genitourinary infections.
3. Early diagnosis and treatment of inflammatory arthritis prevent joint damage, reduce pain, and improve quality of life.
4. Imaging modalities for joint damage and inflammation in inflammatory arthritis include X - rays, MRI, and ultrasound. X - rays show bone changes, MRI detects soft - tissue and bone marrow inflammation, and ultrasound is useful for synovitis and enthesitis.
5. In advanced rheumatoid arthritis, characteristic joint deformities include ulnar deviation of the fingers, swan - neck and boutonnière deformities, and subluxation of the metacarpophalangeal joints.

1. Skin (psoriasis), nail changes, eye inflammation (uveitis), bowel issues, dactylitis.
2. Radiographic: enthesitis, sacroiliitis, joint space narrowing. Triggers: gastrointestinal or genitourinary infections.
3. Prevents joint damage, reduces pain, improves quality of life.
4. X - rays, MRI, ultrasound. X - rays for bone changes, MRI for soft - tissue and bone marrow inflammation, ultrasound for synovitis and enthesitis.
5. Ulnar deviation of fingers, swan - neck and boutonnière deformities, metacarpophalangeal joint subluxation.
