Case Discussion
Tronzo classification is used to classify intertrochanteric fractures:
- type I: incomplete fracture
- type II: no posteromedial comminution, lesser trochanter may be fractured
- type III: posteromedial comminution, the shaft is medially displaced with the neck beak impacted into it
- type III variant: type III combined with greater trochanter fracture
- type IV: posteromedial comminution, the shaft is laterally displaced
- type V: reverse obliquity
