What is a conchodical fracture?

A conchodical fracture is a type of break in bone that occurs in a curved or shell-like pattern, resembling the shape of a conch shell. This type of fracture is typically seen in brittle materials, such as glass or certain types of bone, where the fracture surface is smooth and concave. It is characterized by a lack of sharp edges, making it distinct from other types of fractures. Conchodical fractures often result from compressive forces or impacts that create a specific pattern of failure.
