What's the difference between ankylosis and fusion?

Ankylosis


Definition:

  • (n.) Stiffness or fixation of a joint; formation of a stiff joint.
  • (n.) The union of two or more separate bones to from a single bone; the close union of bones or other structures in various animals.
  • (n.) Same as Anchylosis.

Fusion


Definition:

  • (v. t.) The act or operation of melting or rendering fluid by heat; the act of melting together; as, the fusion of metals.
  • (v. t.) The state of being melted or dissolved by heat; a state of fluidity or flowing in consequence of heat; as, metals in fusion.
  • (v. t.) The union or blending together of things, as, melted together.
  • (v. t.) The union, or binding together, of adjacent parts or tissues.

Example Sentences:
