Abstract

Sindrom karpalnog kanala je stanje koje nastaje uslijed pritiska medijanog živca prilikom njegovog prolaska kroz karpalni tunel u predjelu zapešća. Glavni simptomi su bol i parestezije, posebice noću, u području palca, kažiprsta i srednjeg prsta. U svakodnevnoj kliničkoj praksi ultrazvuk postaje široko rasprostranjena i učinkovita metoda u evaluaciji sindroma karpalnog kanala. Prilikom procjene ozbiljnosti sindroma karpalnog kanala koristimo se različitim ultrazvučnim parametrima. Najčešće su korišteni parametri dimenzija struktura unutar karpalnog kanala, a posebice medijanog živca. Koristimo se površinama poprečnih presjeka (CSA = engl. cross-sectional area) medijanog živca mjerenih na nekoliko pozicija, od proksimalno prema distalno, na podlaktici (CSA-FA = engl. forearm), ulazu (CSA-I = engl. inlet) i izlazu (CSA-O = engl. outlet) iz karpalnog kanala. Prikupljene vrijednosti su uspoređene u različitim omjerima, od kojih je omjer CSA-I / CSA-O odnosno IOR (engl. inlet-outlet ratio), najčešće korišten. Od svih raspoloživih postupaka liječenja, kao što su ortopedska pomagala, lokalna primjena kortikosteroida i TENS-a (engl. Transcutaneous electrical nerve stimulation), kirurški zahvat je najunčikovitiji.

Abstract (english)

Carpal tunnel syndrome is a medical condition due to compression of the median nerve as it travels through the wrist at the carpal tunnel. The main symptoms are pain and parasthesia, especially during the night, in the thumb, index finger, middle finger and the thumb side of the ring fingers. Ultrasound is becoming an increasingly widespread complementary method in the evaluation of carpal tunnel syndrome in a routine clinical practice. There are different ultrasound parameters used to evaluate severity of carpal tunnel syndrome. Most of the parameters are based on measuring the dimensions of structures in the carpal tunnel, especially median nerve. Median nerve cross sectional area (CSA) which is measured on several positions from the proximal to the distal point, forearm (CSA-FA), inlet (CSA-I) and outlet of the carpal tunnel (CSA-O). Obtained values are then compared in different ratios, where the inlet-outlet ratio (IOR) is the one most used. Among all available procedures, such as use of orthopedic devices, local corticosteroid therapy and transcutaneous electrical nerve stimulation, surgery is by far the most efficient.
