Root Explanation

Ankylosis is derived from the Greek word "ankylos" (meaning bent or crooked) and the suffix "-osis" (meaning condition or process). The term refers to a condition characterized by the stiffening or immobility of a joint due to abnormal adhesion and rigidity of the bones.

Memory Tip

Imagine a joint that is 'bent' or 'crooked' ('ankylos') and has a 'condition' ('-osis') that makes it stiff and immobile. This helps you remember that ankylosis refers to the stiffening of a joint.
