The Seinsheimer classification is a system of categorizing subtrochanteric hip fractures based on the fracture pattern of the proximal femoral shaft. The classification was developed by Frank Seinsheimer III in 1978. In the published work, fifty-six patients were treated for subtrochanteric fractures, and their fractures were "classified according to the number of major fragments and the locations and shapes of the fracture lines." This system of classification was used to assess the correlation between type of fracture and success of treatment.Seinsheimer, F. "Subtrochanteric fractures of the femur."
