In geometry, a torus (plural tori) is a surface of revolution generated by revolving a circle in three-dimensional space about an axis coplanar with the circle.he flat torus is a torus with the metric inherited from its representation as the quotient, R 2 / L, where L is a discrete subgroup of R 2 isomorphic to Z 2. This gives the quotient the structure of a Riemannian manifold.
The Lapidus procedure is a type of fusion of the first TMT joint that decreases the movement of that joint and straightens out the first metatarsal and toe. So the Lapidus procedure treats bunions caused by first TMT joint hypermobility.
