Karpaltunnelsyndrom: Årsak

Innhold i artikkelen

Av ulike grunner kan det bli trangt i karpaltunnellen. Nervus medianus kommer da i klem, og det kan oppstå symptomer i nervens funksjonsområde, det vil si i hånden og fingrene, unntatt lillefingeren. De vanligste årsakene til at det blir trangt, er vevsirritasjoner eller betennelser som medfører væskedannelse og hevelse i kanalen, og dermed klem på nerven. Det kan dreie seg om for eksempel senebetennelser. Kroppens væskebalanse påvirkes også av en del hormoner og nyrefunksjonen. Det kan være del av forklaringen på økt forekomst av tilstanden hos gravide, kvinner i overgangsalderen, personer med varig nedsatt nyrefunksjon, diabetes eller stoffskiftesykdom. Leddgikt er en annen sykdom som øker risikoen for tilstanden. Men ofte finner man ingen god forklaring på hvorfor tilstanden har utviklet seg.

Karpaltunnelsyndrom kan også skyldes forandringer etter et beinbrudd i området (håndleddsbrudd) eller overbelastning gjennom ensidige håndbevegelser i yrket. Særlig utsatt er servitører, frisører, skribenter, maskinoperatører, platearbeidere, slaktere, renholdere og personer som arbeider med vibrerende verktøy.
