ASTRA Spine Revision

ASTRA Spine System increases surgeon choice and flexibility to manage various complex spine pathologies across different patient ages and builds with a comprehensive implant and purpose-built instrument options.


  • High strength, low profile implants designed for use with multiple rod diameters and materials.
  • OsteoHold technology with optimized cortical and cancellous zones to maximize grip in osteoporotic bone.
  • Built-in 65° of total angulation in the favored plane in all polyaxial screws.
  • Enhanced locking cap design for easy starting with no cross-threading.
  • Friction-fit head to facilitate rod placement in deformity and complex spine procedures.​
  • Compact yet strong for optimum performance with different rod material choices.
  • All implants accept multiple rod diameters using same instrumentation.​
  • SureGrip is a unique instrument/implant interface for excellent stability.


  • Provides a low-profile connection for instrumentation with exceptional mechanical stability and intraoperative flexibility.
  • Designed to securely anchor the screw in both cortical and cancellous bony anatomy.
  • Allows for ease of rod placement in challenging anatomy in both the thoracic and lumbar spine.​
  • Designed to deliver torque securely under high load applications such as rod-reduction, sagittal and coronal alignment.
  • Eliminates the need to readjust tulip heads, reduces operating time and improves rod path visualization.
  • Ability to match the correct rod material and diameter to the specific patient’s need.​
  • Versatility and adaptation for multiple pathologies and surgical treatments.
  • Provides a rigid connection for accurate and secure maneuvering.


Procedures such as a Pedicle Subtraction Osteotomy (PSO) and a Vertebral Column Resection (VCR) provide surgeons with techniques to correct sagittal deformity. The SpineCraft PSO Instrument Set has specialized instruments designed to aid surgeons in these types of challenging procedures.
