[Common and not so common nerve entrapment syndromes: diagnostics, clinical aspects and therapy].

Altogether, nerve entrapment syndromes have a very high incidence. Neurological deficits attributable to a focal peripheral nerve lesion lead to the clinical diagnosis. Frequently, pain is the dominant symptom but is often not confined to the nerve supply area. Electroneurography, electromyography, and more recently also neurosonography are the most important diagnostic tools. In most patients surgical therapy is necessary, which should be carried out in a timely manner. The entrapment syndromes discussed are suprascapular nerve entrapment, carpal tunnel syndrome, cubital tunnel syndrome, meralgia paraesthetica, thoracic outlet syndrome and anterior interosseous nerve syndrome.
