👉 Crickinite is a type of rare bone disease that occurs in children and young adults. It's characterized by a cluster of small, irregular bones called "cricks" that grow together to form a ball-like structure known as a "cric." Crickinites are usually found at the corners or on the edges of bones, but they can also be found anywhere where there is a cluster of small bones. They're typically seen in children between the ages of 2 and 7 years
