Quick finger – Snap finger – Spring finger – TVS

In the case of the fasting finger (tendovaginitis stenosans), tendon thickening and swelling of the tendon sheath restrict gliding of the flexor tendon through the annular ligament in the area of ​​the metacarpophalangeal joints. This leads to a painful restriction of movement. As a result, the finger while stretching in the flexion position „snap“ and then suddenly „vorschnalzen“. In the advanced stage, the finger can no longer be stretched independently from the bent position.

The ring band is severed during surgery and the tendon can slide freely again.

ganglion

A ganglion – also popularly referred to as a supra leg – is a benign tumor formation in the region of a joint capsule or a superficial tendon filled with joint fluid. They often arise in the area of ​​the wrist, usually on the back of the hand, more rarely on the wrist front. Ganglia can also occur in the region of the flexor tendons of the fingers or over a finger joint. Often, ganglia cause no discomfort and disappear by themselves. However, the swelling may be both cosmetically, as well as with the movement bothersome and by irritation of the joint nerves also be painful. In these cases, surgery is advised.

During surgery, the ganglion with its pedicle is removed from the capsule or tendon sheath.

Sulcus ulnaris syndrome – cubital tunnel syndrome

The Nervus ulnaris („Ellennerv“, colloquially known as „foolish leg“) runs in the area of ​​the elbow and the wrist. A narrowing of this nerve is made initially by numbness and tingling in the little finger, the outer side of the ring finger and the adjacent palm area noticeable. Subsequently, it can lead to decreased strength and paralysis in the hand to muscle atrophy (atrophy) on the metacarpus. The little finger and the ring finger get into flexion position and the spreading of the fingers is difficult (claw or claw hand).

With a surgical procedure, the constricted nerve is released, thus resolving the symptoms.

Carpal tunnel syndrome – CTS

The carpal tunnel syndrome is caused by an entrapment (compression) of the median nerve (median nerve) in the area of ​​the wrist (wrist canal – carpal tunnel). It is one of the most common nerve compression syndromes and usually occurs on both hands.

The disease usually begins with a tingling in the thumb, index and middle finger. A typical symptom of carpal tunnel syndrome is the nocturnal „falling asleep“ of one or both hands.

It comes to a numbness and pain in the area of ​​these fingers to the restriction of fine motor skills and power reduction.

In the advanced stage there is a decrease of the thumbball muscles (atrophy).

During surgery, a dense connective tissue-like ligament (retinaculum flexorum) is severed in the palm of the hand and relieves the nerve.

Dupuytren’s contracture: surgical or syringe

Dupuytren’s contracture – named after the Parisian anatomist Dupuytren – is a benign connective tissue disorder of the palm. Due to an increased formation of collagen, benign, nodular and cord-like connective tissue develop, which can complicate or prevent stretching of the long fingers and the thumb. Over time it comes to the retraction of the fingers.

During surgery, the connective tissue structures are removed, finger nerves and blood vessels are „cleaned“ from the outside. In pronounced cases, ergotherapeutic treatment (finger exercises and scar treatment) makes sense.

A new treatment method offers a simple injection therapy. A tissue-dissolving enzyme (protein) is injected into the nodular strand, which can dissolve the connective tissue fibers.
