Sulcus ulnaris syndrome (SUS)

Ulnar sulcus syndrome (SUS) is a disorder that occurs in the area of the Ellenbogens  and is caused by entrapment or overload of the ulnar nerve in the ulnar groove. This nerve is responsible for the mobility of the hand and for the feeling in the area of the ring finger and little finger .

Symptoms of SUS can include pain, tingling, numbness or weakness in the hand and fingers, and difficulty with fine motor skills. The causes can be varied, from injury or inflammation to prolonged physical stress such as repetitive movements at work or sports.

Diagnostiziert wird das SUS häufig durch die körperliche Untersuchung und gegebenenfalls durch bildgebende Verfahren wie MRT oder CT. Als wichtigste Investigations, however, should be mentioned as electroneurography and electromyography (NLG/EMG).

Treatment of SUS can be conservative or surgical and depends on the cause and severity.

Conservative therapies can include pain medication, physical therapy exercises, and nerve-sparing measures such as wearing a bandage. Surgical treatments may be necessary when conservative measures are ineffective and may include exposing or relocating the pinched nerve.

It is important to diagnose and treat early to prevent further damage to the nerve and to minimize pain and disability. Close collaboration between the patient and the treating physician is essential to ensure the best possible treatment.
