[Abdominal pain due to nerve compression].

Persistent abdominal pain in a 15-year-old girl was diagnosed after examination by the GP, the pediatrician, the gynaecologist and finally, the surgeon as rib-tip syndrome. The patient could be treated sufficiently by the injection of local anaesthetics and corticosteroids. In the rib-tip syndrome hypermobility of the lower ribs irritates the intercostal nerves causing pain along the lower edge of the chest. The condition can be established objectively with the aid of fluoroscopy and electrostimulation, electromyography or magnetic stimulation.
