Professional activities with your hands, such as working on the computer or playing the piano professionally, put a considerable strain on your eyesight and tendinitis is often the result (tendovaginitis). A special form is stenosans tendovaginitis, which is associated with the phenomenon of snapping fingers.
Tendovaginitis stenosans describes inflammation in the area of the flexor tendons, which is accompanied by the formation of tendon nodules, which then lead to restricted movement, since the tendon can no longer slide freely through the so-called ring band. From a certain point, bending and stretching the finger is only possible against resistance, after overcoming which the movement is completed in a kind of snap. Hence the name “snapping fingers”. Other names of the symptoms are Digitus saltans or Springfinger.
Our tendons run in sheaths. Repeated overloads can cause minor injuries and corresponding inflammation on the flexors of the fingers. The tissue swells and so-called tendon nodes form. As a result, the tendons can no longer slide properly through the so-called ring band and corresponding movement restrictions occur. The reduced function can be expressed in the fact that it is difficult to bend or stretch the finger. Even going back to the original position can not happen at all, difficultly or suddenly (quickly). Pain along the course of the tendon and swelling are also often part of the symptoms.
The entire course of the vessels on the affected limb should be considered during the examination. If there are disconnections at classic bottlenecks, this can lead to a traffic jam, which is holistically responsible for the problem. In addition to the mechanical factors, the underlying diseases and conditions related to the tissue and the care must also be taken into account, such as an underactive thyroid, lactation, pregnancy, menopause, diabetes mellitus, amyloidosis (protein metabolism disorder) or rheumatoid arthritis.
First of all, the tendon should be protected so that the inflammation can subside. With accompanying gentle manual therapies, structural impairments can be remedied to a certain extent. It is not uncommon, however, that the snap of the fingers can only be remedied by an operation. (jvs)
