Introduction Method

Using a direct approach, the introducer is delivered to the bone surface, rotating counterclockwise to reduce soft-tissue trauma. The introducer is then advanced, twisting alternately clockwise and counterclockwise, into the bone. Once anchored in the bone surface, the trocar-tip stylet may be exchanged for the drill, which locks together with the perforating cannula to traverse hard bone.
