Fielding classification for subtrochanteric fractures.
Case Discussion
Fielding classification of subtrochanteric fractures is based on the level of the subtrochanteric region through which the fracture extends.
- type I: at the level of the lesser trochanter (most common)
- type II: within the region 2.5 cm below the lesser trochanter
- type III: within the region 2.5 cm to 5 cm below the lesser trochanter (least common)
