Spinal fixation systems and spine implants

Effective solutions to keep your patients moving forward

Ossyn brings together four systems —open pedicle fixation, minimally invasive fixation, vertebral body augmentation and bone cement— on the same titanium alloy and the same instrument logic.

  • Ti-6Al-4V
  • Open and MIS
  • In-theatre support

The line

Four systems covering spine surgery

From open multilevel constructs to vertebral compression fractures, with one supplier and shared design principles.

Openped

Posterior pedicle fixation · open

Thoracic · lumbar · sacral

Dual-thread polyaxial screws, in reduction and cannulated versions, for single and multilevel constructs as an adjunct to fusion.

Unomis

Minimally invasive fixation

Percutaneous or cortical bone trajectory (CBT)

Cannulated, fenestrated screws with extensions that guide the rod through minimal incisions, with an option for cement augmentation.

Vertres

Vertebral body augmentation

T6 – L5

Titanium implant with three-dimensional expansion that restores vertebral body height and remains as structural support.

Osment

PMMA bone cement

Vertebroplasty and kyphoplasty

Low-exotherm radiopaque cement formulated for vertebral body stabilisation.

By clinical scenario

Which system fits each scenario

Explore the spine: each point opens the system indicated for that segment and its clinical scenario.

Openped

Deformity, trauma and multilevel disease

Open posterior pedicle fixation as an adjunct to fusion in degenerative disease, deformity, spondylolisthesis, fractures, tumours and revisions.

Built-in reduction

Extended tabs

They extend the head to capture the rod without extra reduction instruments and are removed at the end, leaving a low profile.

Vertres

How vertebral body restoration works

Minimally invasive transpedicular approach. The implant expands in a controlled way, restores height and stays as structural support.

Transpedicular access

Transpedicular access

Percutaneous access to the vertebral body under fluoroscopic guidance.

Conceptual illustration. It does not replace the surgical technique or the instructions for use, which are provided to the institution.

The clinical problem

Vertebral compression fracture

It is the scenario Vertres and Osment address. Fracture morphology determines the technique and the height restoration.

Wedge fracture

The most common. Height loss concentrates on the anterior wall and pulls alignment into kyphosis.

Biconcave fracture

The endplates give way towards the centre, with the anterior and posterior walls relatively preserved.

Crush fracture

Height loss across the whole vertebral body, with the greatest impact on sagittal alignment.

Main causes are osteoporosis, trauma and tumours. In the United States about 750,000 osteoporotic vertebral fractures are estimated each year (The Spine Journal, 2015;15:281–289).

Osment

Bone cement designed for the vertebra

Cement is where the difference between products shows the most. Osment was formulated around three priorities.

  • Low exotherm. Lower setting temperature than traditional cement, to reduce thermal exposure of bone.
  • Radiopacity. Zirconium dioxide as contrast agent for fluoroscopic control.
  • Working time. A working window suited to vertebroplasty and kyphoplasty.

FAQ

Questions about the Ossyn line

Straight answers for surgeons, scrub teams and technical committees.

What is Ossyn?

Ossyn is Maff Health’s spine line. It groups Openped for open pedicle fixation, Unomis for minimally invasive fixation, Vertres for vertebral augmentation and Osment bone cement.

The systems share titanium alloy and design principles, so an institution can cover open, minimally invasive and vertebral augmentation procedures with one supplier.

What is the difference between CBT and the transpedicular technique?

Cortical bone trajectory (CBT) targets the denser bone of the posterior arch, while the transpedicular technique crosses the pedicle into the vertebral body.

Unomis allows either trajectory with the same screw, whose dual-pitch thread is designed for both cortical and cancellous bone.

What does three-dimensional expansion mean in Vertres?

The implant deploys in a controlled way inside the vertebral body to restore its height, and remains there as structural support while the cement spreads around it.

In balloon techniques the device is removed at the end and support relies on the cement alone.

Can cement augmentation be done through the screw?

Yes. Cannulated and fenestrated versions allow cement augmentation, useful in osteoporotic bone.

Indication and technique are at the surgeon’s discretion and follow the system’s instructions for use.

Why does bone cement exotherm matter?

Cement polymerisation releases heat. A lower setting temperature reduces thermal exposure of the surrounding bone tissue.

Osment is formulated for low exotherm with zirconium dioxide as radiopacifier for visualisation during the procedure.

Do you provide the surgical technique and technical documentation?

Yes. Surgical technique, reference catalogue and test summary are delivered to institutions and distributors, in Spanish and English.
