Alphatec Holdings announced today the commercial release of InVictus minimally invasive, or MIS, SingleStep K-wireless implant delivery system. By completely eliminating the requirement for K-wires in a percutaneous pedicle fixation procedure, SingleStep limits the potential complications associated with inadvertent K-wire advancement during traditional minimally invasive pedicle screw placement techniques.

“This release enhances the functionality and distinction of ATEC’s newly-launched InVictus platform with technology that has been engineered to profoundly improve the elegance of percutaneous fixation,” said Pat Miles, chairman and chief executive officer. “SingleStep enables increased surgeon control of the variables surrounding percutaneous pedicle screw placement.”

InVictus MIS SingleStep

The commercial release of the InVictus MIS SingleStep implant delivery system follows successful evaluations that began in January 2019.

Compared to a traditional percutaneous technique, InVictus MIS SingleStep is designed to reduce procedural steps, instrument passes, screw insertion time, and fluoroscopy, and completely eliminate guidewire management. SingleStep’s innovative streamlined approach integrates seamlessly with SafeOp neurophysiology to add safety, expedience and increased predictability to percutaneous pedicle screw delivery.

“SingleStep represents an evolutionary leap in percutaneous pedicle screw instrumentation,” stated Tyler G Smith of Roseville Orthopedic Surgery and Sports Medicine in Roseville, USA. “By removing steps in the sequence of targeting and implantation, the result is an elegant system that is faster, safer, and more reproducible. In a word, it is simple. It is easy to make a product different, but the new ATEC has made the approach better.”

Key features of InVictus MIS SingleStep

The InVictus SingleStep system has been designed to improve surgical outcomes by simplifying minimally invasive pedicle screw placement procedures.

Key features include:

  • Limits the potential complications associated with inadvertent guidewire advancement by eliminating the requirement for K-wires;
  • Novel ratcheting handle for swift pedicle screw delivery and unprecedented, single instrument-pass functionality;
  • Simplified approach reduces procedural steps by 50%, streamlining screw insertion time and potentially reducing reliance on fluoroscopy;
  • Steerable stainless steel stylet seamlessly perforates the pedicle; and
  • Integration with SafeOp technology reinforces confidence during stylet and screw insertion.
