SPIRA®-O

OPEN MATRIX OLIF

SURFACE BY DESIGN ®

  • SPIRA®-O Open Matrix OLIF and its open matrix design contain multiple pathways throughout the implant for osseointegration.
  • Arched design distributes load evenly across endplates with optimized surface contact. Each implant offers up to 40 points of endplate contact.

  • 3D printed titanium with Surface by Design® Technology, encourages bone cell proliferation with roughened titanium surface. 1,2,3,4,5,6

  • Surface by Design® Titanium roughened surface is designed to have an average pore diameter approximately 500μm - the ideal environment for bony ingrowth. 7,8,9,10

OBLIQUE LUMBAR INTERBODY FUSION PROCEDURE

INSTRUMENTS AND IMPLANTS PASS THROUGH THE MOST NATURAL CORRIDOR TO THE DISC SPACE11

  • Simple retraction and disc access
  • Minimally invasive with maximal visualization
  • Comprehensive set of non-reflective disc preparation instrumentation
  • Straight Instrumentation
  • No orthogonal maneuver required for implant seating
  • DESIGNED SPECIFICALLY FOR THE OLIF APPROACH

    Precision

    Inserter location feature placed at the optimal angle for atraumatic insertion

    Safety

    No toggling of instruments in situ - instruments designed for safe implant delivery under direct visualization

    Innovation

    Implant design utilizes proprietary open architecture and surface technology

    SPIRA®-O INSTRUMENTS DESIGNED FOR:
