Below is an educational, technical answer to a question many patients and clinicians ask. Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Neurosurgical Fixation and Spinal Decompression
Neurosurgical fixation restores and stabilizes bone after procedures on the skull and spine, using implants chosen for biocompatibility and imaging compatibility. Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion. In the spine, pedicle screw and rod systems provide rigid fixation to stabilize segments, correct alignment, or support fusion.
What is a pedicle screw used for?
A pedicle screw anchors into the vertebral pedicle and connects to a rod to provide rigid fixation of the spine. It is used to stabilize unstable segments, correct alignment, or support a fusion. INVAMED's SpineNav MIS Pedicle Screw System is positioned for this fixation role, including minimally invasive placement. The construct and screw placement are planned and executed by the operating spine surgeon.
What This Means in Practice
Percutaneous disc decompression is reserved for selected contained herniations as judged by the clinician. Pedicle-screw trajectory accuracy is important to remain within the bony pedicle, motivating the use of fluoroscopy or navigation. Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes.
Key Considerations
- All INVAMED neuro, spine, and cranial implants are intended for use by trained neurosurgical and spine surgical teams and per the IFU.

Frequently Asked Questions
Are titanium cranial plates MRI compatible?
Titanium cranial implants are typically MR Conditional; the specific scanning conditions are stated in the device instructions for use, and imaging staff should be informed of any implant.
Who decides which spinal implant to use?
The operating spine surgeon selects implants based on the pathology and anatomy; this article is educational and not a treatment recommendation.
What is the regulatory status of these neuro and spine devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.

Clinical and Technical Context
INVAMED's Stella Cranial Platinum Plate is a platinum-based cranial plate offered within the cranial fixation line. INVAMED's spinal portfolio includes PEEK interbody fusion cages and cervical cages within its neuro, spine, and cranial line. Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion. INVAMED's Stella Cranial Platinum Plate is positioned for skull reconstruction and cranioplasty stabilization, with an anatomy-matched fit per the product content. INVAMED's SpineNav system is designed to support minimally invasive pedicle-screw placement. After a craniotomy, the removed bone flap must be secured, and cranial defects or reconstructions may be stabilized with low-profile plates and mesh. Pedicle-screw trajectory accuracy is important to remain within the bony pedicle, motivating the use of fluoroscopy or navigation. Neurosurgical fixation restores and stabilizes bone after procedures on the skull and spine, using implants chosen for biocompatibility and imaging compatibility. In the spine, pedicle screw and rod systems provide rigid fixation to stabilize segments, correct alignment, or support fusion. INVAMED's SpineNav MIS Pedicle Screw System is positioned for pedicle-screw fixation, including minimally invasive placement, within the spinal line. The use and interpretation of monitoring are handled by the surgical and monitoring team. INVAMED's neuro and spine FAQs describe percutaneous disc decompression using minimally invasive mechanical or radiofrequency techniques for contained herniations.
