Russell-Taylor Classification (Subtrochanteric Fracture)
The Russell-Taylor classification of subtrochanteric femur fractures, by piriformis-fossa involvement (type I intact, type II involved) and lesser-trochanter status (A attached, B detached), types IA/IB/IIA/IIB.

Example
- Russell-Taylor type
- IA - piriformis intact, lesser trochanter attached
Result: Russell-Taylor type IA: the piriformis fossa is intact and the lesser trochanter is attached.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Type IA
- Piriformis fossa intact; lesser trochanter attached.
- Type IB
- Piriformis fossa intact; lesser trochanter detached.
- Type IIA
- Fracture into the piriformis fossa; lesser trochanter attached.
- Type IIB
- Fracture into the piriformis fossa; lesser trochanter detached.
What you enter
- Russell-Taylor type
