Rheumatoid Arthritis
Rheumatoid Arthritis is an inflammatory condition that can affect not only the joints, but also other body systems such as skin, eyes and heart. This is an autoimmune disease that occurs when the body’s immune system attacks its own tissues. This is a serious complication that can lead to other diseases.
Rheumatoid Arthritis can cause trigger finger. Synovial proliferation can lead to isolated nodules of rheumatoid on tendons. The size and location of the knots in the flexor tendons determines the trigger point. Four types of trigger fingers can be seen in patients with rheumatoid arthritis. First, the condition is similar to rheumatoid-induced trigger finger. Hyperproliferation occurs in the synovium. In the second condition, nodules or bumps are present in the distal part of the palm. This causes a finger lock into a bent position. There is also a third type of trigger fingers seen in rheumatoid patients. In this case, nodules form on the flexor profundus (muscle in the forearm which flexes the fingers) muscle over the proximalpharynx. This locks the finger into extension. The finger cannot be mobilized. In the fourth type, the trigger finger is generalized within the fibroosseous canal. This results in stiffness.
