Ortholox® UHMWPE Spinal Posterior Fixation System
UHMWPE based Ortholox® UHMWPE Spinal Posterior Fixation System* is designed to eliminate most of the problems caused by conventional posterior pedicle screw systems in following diseases;
*in degenerative cases like spinal fusions,
*in correction surgery for spinal deformities such as scoliosis, kyphosis and spondylolisthesis,
*in spinal traumas.
It is a dual band system woven with UHMWPE fibers. Thanks to its simple instrumentation, using sublaminar passage technique, it passes under the lamina easily and is attached to the rod with the help of a tulip. By means of the patented torque applicable Tensioner; the rod can be inserted into tulips safely. There are various tulips compatible with rod diameters between 3.5-6.3 mm for all posterior column procedures including cervical region.
Ortholox® UHMWPE Spinal Posterior Fixation System is manufactured from Medical Degree Ultra High Molecular Weight Polyethylene material.
For Ortholox® UHMWPE Spinal Posterior Fixation System, very thin fibers are woven in the form of bands with a width of 3 mm (cervical) and 5 mm to form a multifilament material.
- By means of its wide cross section, it eliminates single-point stress.
- Pressure on lamina is distributed and thus decreased thanks to the wide surface of the band.
- By means of its wide surface, it is more reliable in osteoporotic bones when compared to pedicle screws or hooks.
- Each band has a load carrying capacity of over 1600 N. (8 bands=12800 N)
- Thanks to the blunt tip of the bendable titanium guide strip that pre-assembled at the end of the band, it does not damage the soft tissue, and does not pose a threat for the surgeon during the procedure.

- It does not cause damage to lamina structure as the metal wires during and after surgery.
- It is suitable for use in patients on whom the use of screws is risky and who have thin pedicle anatomy.
- It minimises metal corrosion in bone structure.
- Since it has tulips for use with rods of different diameters, it is compatible with almost all different titanium or CoCr posterior spinal screw-hook-rod systems existing at hospitals.

Ortholox® UHMWPE Spinal Posterior Fixation System is highly flexible, it can be manipulated easily.
- It does not lead to complications resulting from tearing and breakage since it has a higher elastic modulus when compared to titanium or CoCr cables and sublaminar wires.
- Its flexible structure ensures a long-term dynamic compression.
- It has a high load carrying capacity.
- Since the bands are manufactured from UHMWPE material, they are radiolucent and thus, they do not cause artifact in post-operational MRI follow-up and the position of the vertebral column and the process for the union of the fracture, if any, can be followed-up more easily in the post-operational x-ray.

In Ortholox® UHMWPE Spinal Posterior Fixation System, thanks to the Tensioner, it is ensured that the rod is inserted into the tulip easily at the appropriate tension. It provides a simple, effective and easy-to-use surgery with only 5 instruments.

In Ortholox® UHMWPE Spinal Posterior Fixation System, a bendable titanium guide strip, tulips and set screws that are manufactured from highly biocompatible (TI-6AL-4V-ELI) alloy are available.
- It is MRI compatible.
- Once the set screw is tightened and fixed using a torque screwdriver, it does not loosen or unlock by itself.
- During the procedure, the set screw can be loosened using a standard screwdriver in order to re-apply tension and thus OR time is shortened.
In Ortholox® UHMWPE Spinal Posterior Fixation System, dual bands with a width of 3mm and 5mm and a length of 250mm are available as preassembled with Titanium Guide Strip on one end and titanium tulip on the back end, and in ready-to use sterile packs in the following rod diameters:
- 3.5mm (Band Width 3mm)
- 4.5mm (Band Width 5mm)
- 5.0mm (Band Width 5mm)
- 5.5mm (Band Width 5mm)
- 6.0mm (Band Width 5mm)
- 6.3mm (Band Width 5mm)
