ASTRA Deformity Spine System

The 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.

Additionally, ASTRA Deformity Spine System is compatible with SpineCraft's comprehensive PSO Instrument Set.
Features:
  • The system employs a Ø5.5mm, Ø6.0mm or Ø6.2 mm rod diameters made of titanium alloy or cobalt chrome alloy.
  • All standard polyaxial screws, uniplanar screws, and hooks are very compact, yet strong, for optimum performance with different rod material choices.
  • All screws are designed with Dual Core Technology and Double Lead Thread.
  • All ASTRA screws have a double lead thread design with optimized cortical and cancellous zones.
  • Polyaxial screws and uniplanar screws are available in Ø4.50mm diameter and start from 25mm length. Reduction screws are also available in different diameters and lengths.  This makes the system particularly suitable for deformity correction.
  • All screws are available as self-tapping.
  • ASTRA polyaxial screws have a friction-fit head designed to facilitate rod placement in deformity and complex spine procedures.
  • The ASTRA Spine System includes a cross connector design, which provides very low profile and versatile connection between the two rods, regardless of their orientation or level.
  • ASTRA titanium hooks & screws are color-coded by screw diameter/hook throat size.
  • ASTRA provides several unique, differentiated connectors with Z-rods to provide more intra-operative options for Revision/Extension procedures.
  • 8.50mm and 9.50mm diameter screws are available for Revision and S2AI Iliac fixation procedures.
  • High angulation, low profile S2AI Screws with T27 drive for higher insertion torque are compatible with 5.5, 6.0 and 6.2mm rods and available with both solid and cannulated shanks.
Benefits:
  • 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, providing versatility and adaptation for multiple pathologies and surgical treatments.
  • Provides a rigid connection for accurate and secure maneuvering.
  • Integrated, navigation-ready, occiput to pelvis correction solution
