ASTRA Degenerative Spine System

ASTRA Degenerative Spine System includes Dual Core and Double Lead Thread Screws, offering fast and controlled screw insertion with outstanding pullout resistance.

Features:

Low proﬁle implants designed for use with multiple rod diameters.
OsteoHold screw 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, not just in “favored-angle” screws.
Optimized locking cap design for easy starting with no cross-threading.
Friction-ﬁt screw head to facilitate rod placement in deformity and complex spine procedures.
All implants accept multiple rod diameters & materials, using the same instrumentation, providing great operative flexibility.
SureGrip is a unique instrument/implant interface for excellent stability and ease of use.
Purpose-designed sacral-alar-iliac (SAI) screws and instruments.
The system is navigation-ready with complete set of navigation instruments.

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
