How does one describe a fracture displacement?
Fracture displacement description:
- Direction of distal portion
- Eg. Halux valgus
- The distal toe is pointed laterally
Eg. Varus knees - The distal tibia is pointed laterally
- The distal toe is pointed laterally
Five fracture positioning parameters (DDART)
Fracture fives DDART
- Dislocation
- Displacement
- Angulation
- Rotation
- Translation
