This range includes all the bones of the leg: tibia, fibula, patella, femur and occasionally hemi-pelvis.
These bones can be ordered separately, or assembled in many different combinations.
For example:
Femur + Tibia
Femur+ Tibia + Patella
Femur + Tibia + Fibula
Femur + Tibia + Patella + Fibula + Hemi-Pelvis (complete leg)
Tibia + Fibula
...
The bones are made of solid foam, which is a realistic material and enables you to place implants as if you were operating on a real human leg.
