To become stiff or immobile; to fuse or stiffen (joints) through disease or lack of use, also spelled 'ankylose.'
From Greek 'ankýlōsis' (stiffening of joints), from 'ankýlos' (bent, crooked). Medical terminology adopted from ancient Greek anatomical observation.
Anchylose comes from the same Greek root as 'ankle'—both refer to joint movement, but ankylosis is when joints refuse to move anymore.
