A Cohesive Cellular Allograft with Viable Cells
ViaCell™ is a cellular allograft containing viable cells including mesenchymal stem cells and osteoprogenitor cells, which are essential requirements for bone formation. The components of ViaCell™ provide the three essential elements of bone formation:
- Osteogenic Cells
- Osteoconductive Scaffold
- Osteoinductive Growth Factors
ViaCell™ is a cohesive putty that can easily be molded and delivered to the treatment site.
Highest Average Cell Count
ViaCell™ contains an average of at least 700,000 cells/cc, of which ≥20% are mesenchymal stem cells and osteoprogenitor cells.
The demineralized cortical fibers provide cohesive putty-like handling.
The provided cell strainer helps decant cryoprotectant without loss of product, and no additional rinsing is necessary.
Time-sensitive aseptic tissue processing has been refined for maximum cell viability.
ViaCell™ is minimally processed human tissue regulated by the FDA under 21 CFR Part 1271and Section 361 of the Public Health Service Act.
The QUARTEX™ Occipito-Cervico-Thoracic (OCT) Stabilization System offers a variety of solutions to the challenges associated with posterior OCT fusion to aid in easier construct assembly. With a comprehensive range of instruments, including threaded drivers and streamlined reduction tools, installation of implants is swift and simple in the midst of complex pathologies.
- Screw Head Capability: The QUARTEX™ screw head accepts a 3.5mm or 4.0mm rod and offers 90° of conical angulation.
- Refined Instruments: Stable threaded drivers, efficient reduction options and flexible tools facilitate construct assembly.
- True Thoracic Pedicle Screw Offerings: QUARTEX™ offers true thoracic screws with diameters up to 5.5mm, to accommodate varying patient anatomy with one comprehensive system.
Rod Link Reducer
3-PLANE DEFORMITY CORRECTION TECHNIQUE
Originally developed at the Texas Scottish Rite Hospital for Children, the Rod Link Reducer technique is designed to aid in the correction of severe spinal curvatures with a novel set of instruments. This technique increases leverage to manipulate the spine in the axial, coronal and sagittal planes.
During the procedure, Manipulating Arms are attached to provisional rods which are placed proximal and distal to the apex of the curve. The Manipulating Arms are used to correct the deformity in three planes. The deformity is manipulated into a corrected position, then the construct is rigidly locked in place while a permanent rod is installed on the contralateral side.

REDUCTION TECHNIQUE OVERVIEW
The first manipulation is axial derotation of the spine and the rib cage for transverse (axial) correction. This is performed by pressing down on the manipulating arms.
The second manipulation is compression of the spine on the convexity for coronal correction. This is performed by bringing the manipulating arms together.
The third manipulation is to restore thoracic kyphosis for sagittal correction. This is performed
- 8mm of Translation: Integrated mechanical reduction feature allows up to 8mm of continuous translation
- Enhanced Endplate Fixation: Implant adjustability allows for optimal cortical bone screw purchase
- Self-Locking Reduction Feature: Simplified procedure with no additional locking step after translation
- Midline Instruments: Midline implant holder allows for maximum visualization and access through a small insertion window with minimal interference
