Fixation Elements are offered in diameters from 1.6mm to 3.0mm, in lengths from 60mm to 125mm, are made of 316L stainless steel, and are available with and without hydroxyapatite (HA) coating.
Bone Screws with diameters of 3.0mm have a self-drilling and self-tapping tip and do not require predrilling. The two-diameter geometry ensures balanced stresses on the two cortices. They are available in lengths of 60mm, 80mm and 100mm.
When the Bone Screw is inserted, the self-drilling tip creates a hole the size of the smaller diameter. The first self-tapping section of the screw taps and removes the bone facilitating the insertion of the smaller diameter part of the screw into the bone. The second set of self-tapping threads facilitates the larger diameter threads to enter into the cortex. The larger diameter is inserted revising any ovalization caused by the smaller diameter section of the screw.
The HA-coated bone screws are fully coated (up to the first reference notch) and are available in lengths of 60mm and 80mm.
Both 1.6mm diameter and 2.0mm diameter threaded wires are 125mm long with 15mm of threads at the tip and are 316L stainless steel.
