What does the suffix -desis denote?

The suffix -desis originates from the Greek word "desis," meaning binding or fusion. In medical terminology, it is commonly used to refer to surgical procedures aimed at fixing or fusing two structures together. This can be seen in terms like "arthrodesis," which indicates the surgical fusion of a joint, effectively stabilizing it. Thus, when the suffix -desis is attached to a root word, it typically implies a procedure that creates a permanent bond or limitation in movement, thereby addressing structural instability or pain associated with joint or bony interactions.
