Finger rheumatoid is known as finger joint rheumatoid in clinical practice. The disease is mainly determined by means of clinical symptoms, laboratory and imaging examinations of the joints. Since the early stage of rheumatoid rheumatism of the finger joints may be in the atypical or inactive stage, it is necessary to consult a doctor for serological tests as well as imaging tests: 1. Clinical symptoms: Patients will have morning stiffness of the finger joints, which can last for about one hour. There is also swelling of the knuckles, soft tissues, or the presence of effusion, usually symmetrically distributed, which may be present as subcutaneous nodules at the bony prominence, on the surface of the extensor tendons, or around the joint. There is significant symmetric, persistent pain with pressure in the joint and the affected joint may have brown pigmentation. In severe cases, joint deformity and functional impairment may occur. 2. Laboratory tests: serum RF and anti-CCP antibody titers are usually positive to varying degrees. 3. Imaging tests: X-rays, joint ultrasound and MRI may be performed to detect bone erosion or significant bone decalcification in the affected joints and adjacent areas. Although rheumatic diseases are lifelong diseases, good control effects can generally be obtained through early treatment and active intervention control, which can relieve the discomfort of patients’ finger joints to the greatest extent and improve their quality of life.
