Re: LISS?

Dear friends,
Less Invasive Stabilization System (LISS) is around at least from 1977 (Krettek's group from Hannover, Germany, had first publications in Injury); before that PC-Fix (Point Contact Fixator) was in use, mostly in Europe.
The main advantages of the system are:
- Fixed angle screw-plate interface (locked screw head inside of the plate;
similar to spine systems - pedicular screws) allowing for:
a. Much higher resistance to pull out forces
b. No need to penetrate opposite cortex (especially advantageous in using just one cortex in periprosthetic fractures...)
c. Less screws are necessary with longer plates (bridge plating technique)
d. More biological technique (at least the opportunity): the additional damage of the periosteum by plate is minimized ("internal fixator")...
This is a truly revolution in ortho-trauma and locking plating systems are very dominant now (at least in western countries). Mathys (Synthes) was the first manufacturer (started with Distal Femoral LISS), and now the other big companies (Smith and Nephew, Ace-Depuy) have it available as well..
I hope this helps,
