In short, fractures can be classified into the following types:

First, based on the integrity of the skin and mucous membrane at the fracture site, it can be classified into closed fractures and open fractures.

Second, based on the shape and degree of the fracture. It can be categorized into oblique fractures, transverse fractures, spiral fractures, comminuted fractures, greenstick fractures, impacted fractures, compression fractures, and bone injuries.

Third, based on the stability of the fracture ends, it can be classified into stable fractures and unstable fractures. Among unstable fractures, these include oblique fractures, spiral fractures, and comminuted fractures. Thus, fracture classification fundamentally falls into these major categories.
