Rheumatism is a common self-immunological disease, which can cause great damage to the patient ‘ s joints, with a more typical and disturbing display of deformation of the finger, with complex and multifaceted causes.
First, in terms of the pathological basis of rheumatism, the immune system, which is inherently an organism, has been disturbed by the mistaken identification of its own joint tissue as an external “enemy” and has launched an immunization attack. During this process, a large number of inflammatory cells gather at the joints, and their own antibodies, such as rheumatizers and anti-accumulator antibodies, are involved, leading to inflammation of the joints. Inflammated by inflammation, the muscular membranes of the finger joints become full of blood, oedema and are growing thicker, which, like the “aggressors”, gradually erodes the surrounding cartilage, bone and radon around the joints.
With the development of the condition, the continuous inflammation of the fungi increases the pressure within the joint cavity. The original smooth cartilage began to wear, destroy and lose its normal buffer and protective function as a result of prolonged inflammation and abnormal pressure. It’s as if the key parts of a sophisticated machine have been damaged and normal joint activity is difficult to sustain. At the same time, increased lubricant membranes may also encroach on the ligaments and mussels around the joints, resulting in a decrease in their strength and elasticity. These organizations, which would have been able to stabilize the joints, assist in joint activity, become loose or convulsive, further affecting the normal shape and functioning of the finger joints.
Moreover, rheumatism is a chronic and progressive disease, and long-term inflammation is repeatedly irritated and causes bone changes. The osteoporosis occurs under an inflammatory “attack” at the finger joint, which becomes fragile and more susceptible to destruction and absorption. Moreover, there may also be an increase in the bone mass due to the destruction of the joint structure and abnormal stress, and the formation of abnormal structures such as femurs, which can lead to changes in the shape of the finger joints, such as the appearance of swelling and deformity of the joints.
In addition, people with rheumatism tend to inadvertently reduce the activity of their fingers because of symptoms such as pain, rigidity, and long periods of brakes cause the muscles around the joints to shrink from their use and their muscles to decrease. The muscles play an important role in maintaining the normal position and form of the joint, and once the muscles shrink, they do not perform well to stabilize and support the joints, and they are more prone to anomalies in their activity and stress, increasing the degree of deformation of their fingers.
At the same time, in everyday life, even minor external forces, such as holding things, holding fists, etc., can be an aggravating factor for already damaged and fragile finger joints, which, with their repeated effects, are moving one step at a time towards deformation, leading to the appearance of typical deformations, such as swan neck deformations and button-button deformities, which cause great inconvenience to the lives of patients.
