The description cortical means that the pilot hole must be pre-tapped prior to screw placement. Cortical Self Tapping means that the screw itself has a self tapping tip and cuts its own thread. Self tappers work very well in all but the hardest cortical bone. It recommended that surgeons using self tappers keep a tap ‘just in case’. Each Kit contains all you need including screws and implants.
Use of Self Tapping Screws can save considerable time and trauma. Pull out strength is not affected provided the self tapping flutes lie outside of the cortex. Self Tapping Screws are less effective in dense cortical bone. e.g. calcaneus. It is advised that an appropriate tap be available should the need arise. Drill data: Pilot Drill 1.1mm, Clearance Drill 1.5mm.
Self tapping flutes at the tip obviate the need for pre-tapping which saves time and reduces time related complications. Pull out strength is not affected provided the self-tapping flutes lie outside the bone cortex. Drill data: Pilot Drill 1.5mm, Clearance Drill 2.0mm.
Titanium Screws and Plates are very commonly used in man particularly for maxillofacial repairs. The most important benefit in this application is that Titanium does not interfere with MRI scans. Compared to stainless steel Titanium is lighter and much more osteo compatible.

Compared to stainless steel Titanium is lighter and much more osteo compatible. The major application in veterinary orthopaedics is in conjunction with the TTA cruciate procedure.
This type of Screw is becoming increasingly popular in both human and veterinary orthopaedics. Self tapping flutes at the tip obviate the need for pre-tapping which saves time and reduces time related complications. Pull out strength is not affected provided the self tapping flutes are positioned outside the cortex.
