The palmar fascia of the hand contracts and curves one or more fingers, usually the ring and little finger, towards the hand. This membrane is surgically removed in order to once again be able to stretch out the fingers. Colloquially this affliction is called Viking disease.

A genetic, hereditary disorder that can occur in both the palm and the sole of the foot. Sometimes the hands may require surgery, but never the soles of the feet.

The operation is performed under local anaesthesia. The fascia is removed so that the finger/fingers can stretch out again.
