FIRST-TIME-RIGHT

1. Primary stability

Providing sufficient stability avoiding micro motion and allowing direct bony ingrowth

MACRO ROUGH SURFACE

Shaped for smooth insertion, to adapt to endplate anatomy and allowing sagittal and coronal alignment

ANATOMICAL DESIGN

2. Osteo active scaffold

Micro-structure and nano-surface for natural bone ingrowth

CELLULAR TITANIUM®

Size and shape of the pore do matter

MICRO-STRUCTURE

diamond shape ideal size (~650 µm) 80% porosity maximal cell surface contact area proper space for vessels and bone cells

Chemical and heat treatments increase total surface for cell attachment and potentially add to biological activity

NANO-SURFACE

Close to cancellous bone - possibly avoiding stress shielding and implant subsidence

MODULUS OF ELASTICITY

The osteo active scaffold is misleading the osteoblasts to start the bone healing process and bone maturation.

3. Spinal balance

Designed to help restore sagittal and coronal alignment

Neck and arm-pain for several months

Clinical complaints improved immediately after the operation and are currently still resolved

Note densifying of trabecular structure in vertebral body from 3 months on, especially in the upper vertebrae.

Note thin white layers on both sides of the cage, indicating active bone-ingrowth in the EIT Cellular Titanium® structure.

Settings of (wide) window 2800-3200, and level 1000-1250 create optimal imaging to allow assessment of bone ingrowth in a porous titanium implant

WHAT ARE THE BENEFITS OF FIRST-TIME-RIGHT?

Quick elimination of pain, fast return to normal life and avoidance of re-operation

BETTER FOR PATIENTS

One-time-right without a learning curve and more patient satisfaction

BETTER FOR SURGEONS

Optimal imaging minimizing disturbing artefacts on MRI and CT scans

BETTER FOR CLINICAL EVALUATION

Fast rehabilitation and quick return to normal activities

BETTER FOR SECOND LINE CARE

Effective surgeries, positive press and strong position towards insurers

BETTER FOR HOSPITALS

Cost-effective procedures when lowering number of revision surgery

BETTER FOR INSURERS

Is accepting a failure rate useful

when it is not necessary?

Will you take this next step in

fusion technology?
