Today’s screw technology is not enough for tomorrow.

Biomech Innovations is pioneering Variable Fixation, the innovative locking screw technology naturally transitioning from rigid to dynamic stability during treatment[1].

Variable Fixation Locking Screw



Variable Fixation Locking Screws (VFLS®) are innovative locking screws boosting new bone formation through three fixation phases.

Rigid fixation
Respects inflammatory processes and blood vessels formation.

Progressive Dynamization
Boosts the production
of new bone.

Dynamic fixation
Allows new bone

The ability to foster the healing process and increase the treatment success rate would be a significant advancement.

How it works


Replaces existing screws or can
be used alongside them.

The principle can be used for
most long bone fractures.

Uses existing surgical
procedures and instruments.
