Tenon
Definition:
(n.) A projecting member left by cutting away the wood around it, and made to insert into a mortise, and in this way secure together the parts of a frame; especially, such a member when it passes entirely through the thickness of the piece in which the mortise is cut, and shows on the other side. Cf. Tooth, Tusk.
(v. t.) To cut or fit for insertion into a mortise, as the end of a piece of timber.
Example Sentences:
(1) Meticulous handling of the graft (using a Goeller trephine and Tenon's traction sutures), filleting Tenon's capsule and avoiding cautery of the graft bed may minimize graft necrosis and atrophy.
