Rheumatoid arthritis is an autoimmune disease of unknown origin. It is characterized by a symmetrical and multiple involvement of small joints throughout the body, with the most characteristic involvement of the wrist, metacarpophalangeal and proximal interphalangeal joints. The toe joints are also small joints, therefore, rheumatoid arthritis can involve the toe joints. Patients with toe joint involvement are more severely affected and should be taken seriously. The common features of toe joint involvement in rheumatoid arthritis and finger joint involvement are: synovitis, joint bone destruction, joint deformity, and functional limitation; the clinical manifestations and quality of life of patients with different joint involvement vary: early RA can involve the foot joints joint inflammation, ligament swelling, foot surface widening, and difficulty in walking and wearing shoes; the 2nd and 3rd toes are mainly weight-bearing, and the inflammatory damage and gravitational force cause the dorsal half of the toe joint to be damaged. Dorsal subluxation of the toe joint due to inflammation and pain —- painful deformity Due to toe inflammation and pain, the patient’s foot follows the ground when walking and the plantar fat pad moves forward —- callus, plantar pain Bursitis of the mother toe Sliding mold granulomatosis, cyst formation, rupture —- exostosis of the first toe Spur navicular, spur tarsal joint —- posterior foot pain Achilles tendon bursitis or RA nodules Tibiofibular spur ligament involvement —- heel pain, plantar pain distal interphalangeal joints are less commonly involved
