Index Finger Symptom

Index sign or de Quervain's sign is a medical phenomenon characterized by excruciating pain with certain types of finger movements. This symptom is named after the Dutch surgeon and pathologist Nicolas de Quervain, who first described it in 1678.

The index symptom has two main forms of manifestation: primary and secondary. The primary form is the main form, and the secondary form is secondary, which occurs against the background of other diseases or injuries. It should be noted that the diagnosis of this symptom is carried out not only on the basis of an external assessment by a specialist, but also with the help of instrumental research methods - CT, ultrasound, etc.

The primary manifestation of the index symptom may occur due to the following reasons:

- hand injuries; - inflammation of the tendons, for example de Quervain's tenosynovitis, de Quervain's syndrome, etc. - joint diseases such as tendonitis, bursitis and arthritis.

The secondary manifestation of this symptom is caused by the following reasons:

1. arthrosis of the joint: damage to the cartilage tissue of the interphalangeal joint, which contains the synovial bursa and the vessels passing through it. If this arthrosis is accompanied by an inflammatory process in the joints, compression of the vessels passing through it occurs. This, in turn, leads to poor circulation and triggers symptoms. As pathologies worsen, vasospasm occurs, leading to a persistent change in vascular tone and malnutrition. Dystrophic
