What does the suffix "-desis" mean?

The suffix "-desis" specifically refers to the binding or fusion of a body part, often used in medical terminology to describe surgical procedures that stabilize a joint or fusion of tissues. For instance, in terms like "arthrodesis," it indicates the surgical fusion of a joint to provide stability and alleviate pain resulting from joint disorders. This is crucial in orthopedic surgery, where achieving a stable joint environment is necessary for proper healing and function.

The other options relate to different medical meanings: a puncture or tap is usually indicated by the suffix "-centesis," viewing an internal organ is associated with the suffix "-scopy," and the measurement of lung function generally involves terms tied to "-metry" or similar. Knowing these distinctions is vital for understanding medical terminology and the specific contexts in which different suffixes are used.
