Clinical overview
Product overview
What is Cortex Screw？
Cortical screws are defined by their smaller pitch and greater number of threads. Their thread diameter to core diameter ratio is less, and they are fully threaded. As their name suggests, cortical screws are used in cortical bone; also known as compact bone, this is the dense outer surface of bone that forms a protective layer around the internal cavity.
It makes up nearly 80% of skeletal mass and is extremely important to body strucure and weight bearing (it is highly resistant to bending and torsion).
