annulus â(plural annuluses or annuli). 1  A ring-or donut-shaped area or structure. ( 2 geometry) The region in a plane between two concentric circles of different radius. ( 3 topology) Any topological space homeomorphic to the region in a plane between two concentric circles of different radius.
The annulus can tear or rupture anywhere around the disc. If it tears and no disc material is ruptured, this is called an annular tear. The outer 1/3 of the discâs annular ring is highly innervated with pain fibers. Thus, if a tear involves the outer 1/3 it may be extremely painful.This tear will heal with scar tissue over time but is more prone to future tears and injury.f it tears and no disc material is ruptured, this is called an annular tear.
