The new ORTHObones STANDARD have a hard cortical bone and softer, spongy bone (spongiosa). The two-component structure ensures particularly realistic haptics and appearance of these workshop bones. The surface of the ORTHObones STANDARD is not as rigid as that of ORTHObones PREMIUM and is therefore more suitable for carrying out medullary nailing, for example. Overall, mechanically manipulating the new ORTHObones STANDARD is easier.
