There is a window of opportunity in fracture healing.

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

Today's screw technology is not enough for tomorrow.

Variable Fixation Locking Screw VFLS

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 calcification.

Aiming at increasing the treatment success rate by fostering the healing process.
