Radio – Ulna

Intrauma straight locking plates for the treatment of diaphyseal fractures of radius and ulna have an anatomic design and innovative characteristics.

The patented screw-plate locking system eliminates the risk of cross threading between the screw and plate and ensures a simple operative technique.
O’nil plates transfer the forces acting on the fracture in a flexible way, to work like an external fixator.
Compression is sometimes required to reduce certain types of radius-ulna fractures: through some combined slots and with the aid of hemispherical head to assemble to O’nil screws, it is possible to easily carry out auto compression.

Benefits and advantages
