Om Freyr Gauti Sigmundsson

Freyr Gauti Sigmundsson är överläkare på ortopediska kliniken, Örebro Universitetssjukhus. Freyr Gauti disputerade i Lund 2014. Hans avhandling handlade om prediktiva faktorer för utfallet efter kirurgi för spinal stenos i ländryggen.

Freyr Gauti bedriver inte bara degenerative ländsryggsforskning tillsammans med sina kollegor på Ortopediska Kliniken i Örebro men deltar även i forskningssamarbete med ryggkirurger i Malmö, Danmark, Norge och Japan.

Han intresserar sig för uppbyggnad av ryggforskning och avancerad ryggkirurgi i region Örebro Län.
