The Reliability of Classifications of Proximal Femoral Fractures with 3-Dimensional Computed Tomography: The New Concept of Comprehensive Classification

Figure 2

Pure type fractures in “area classification.” When there is a fracture in only the first area, the fracture is classified as a pure first area fracture, and so on. Thus, pure 1 type is the so-called neck fracture, pure 2 type is the so-called basicervical fracture, pure 3 type is the so-called trochanteric fracture, and pure 4 type is the so-called subtrochanteric fracture.
