Seinsheimer classification
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.[1]
The system has been criticized for having poor inter-rater reliability.[2]
Classification
| Type | Description | |
|---|---|---|
| I | less that 2mm displacement | |
| II | A | 2-part transverse fracture |
| B | 2-part spiral fracture with lesser trochanter attached to the proximal fragment | |
| C | 2-part spiral fracture with lesser trochanter attached to the distal fragment | |
| III | A | 3-part spiral fracture with lesser trochanter as separate fragment |
| B | 3-part spiral fracture with butterfly fragment | |
| IV | Comminuted fracture with 4 or more fragments | |
| V | Fracture with proximal extension into the greater trochanter | |
