Epiphysiodesis is a medical term used to describe a surgical procedure that involves fusing the growth plate of a bone. The procedure can be performed on any joint with a growth plate, but it is commonly performed on the knees in children and adolescents to prevent further growth if the difference in leg length between the two legs is significant. Synonyms for the term include "epiphyseal arrest," "growth plate fusion," "growth plate stapling," and "growth plate surgery." While all of these terms refer to the same surgical procedure, they may be used interchangeably depending on the context or specialty of the physician using them.
