External Fixation

Application of EF techniques with the Kirschner-(KE) external fixator clamp is difficult and tedious.  If increased stability of a construct requires additional transfixation pins, the construct must be disassembled in order to load additional clamps onto the connecting rods. 

With the Securos system, after a fixation pin is placed, the U-shaped clamp component is combined with the head component and slid onto the fixation pin.  The 2 components are then snapped onto the connecting bar.  The bolt is then inserted and tightened.  By the head component of the clamp engaging the connecting bar with a ‘spot weld’, rather than the U component bending to ‘embrace’ the connecting bar, the pin-connecting bar unit is more rigid than with the KE type clamp.  Further, the Securos clamp can accommodate positive-profile threaded transfixation pins.

Positive-profile threaded pins are better than smooth pins because threads reduce bone pin strain by increasing surface area between bone and fixator over which forces can be transmitted, resulting in the clinical feature of greater holding power.

The Securos Aiming Device greatly simplifies application of a full pin and ensures accurate placement.  This device allows for sleeved drilling of pin holes and positive-profile pins.
