This article explains, in educational terms, cranial plate material — how the technology works and where it fits. Which implants and approach are appropriate is determined by the operating neurosurgeon or spine surgeon based on the pathology and anatomy. 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
Which implants and approach are appropriate is determined by the operating neurosurgeon or spine surgeon based on the pathology and anatomy. After a craniotomy, the removed bone flap must be secured, and cranial defects or reconstructions may be stabilized with low-profile plates and mesh. Neurosurgical fixation restores and stabilizes bone after procedures on the skull and spine, using implants chosen for biocompatibility and imaging compatibility.
Titanium and Platinum Cranial Materials
Cranial implants use biocompatible metals such as titanium and platinum, chosen in part for their imaging compatibility and long-term tissue tolerance. Material selection can influence artifact on imaging and the profile of the implant beneath the scalp. INVAMED's Stella Cranial Platinum Plate is a platinum-based cranial plate offered within the cranial fixation line. The choice of material for a given patient is made by the neurosurgeon in line with the device labeling.
Design and Technical Notes
INVAMED's neuro, spine, and cranial line spans cranial fixation, pedicle-screw stabilization, interbody fusion, and adjunct agents used in these procedures. All INVAMED neuro, spine, and cranial implants are intended for use by trained neurosurgical and spine surgical teams and per the IFU. Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes.
Key Considerations
- Interbody cage material and dimensions are matched to the disc space, desired lordosis, and fusion strategy.
- Pedicle-screw trajectory accuracy is important to remain within the bony pedicle, motivating the use of fluoroscopy or navigation.
- Percutaneous disc decompression is reserved for selected contained herniations as judged by the clinician.
Frequently Asked Questions
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 INVAMED pedicle screw system called?
INVAMED's pedicle-screw system is the SpineNav MIS Pedicle Screw System, positioned for spinal fixation including minimally invasive placement.
Does INVAMED offer PEEK interbody cages?
Yes. INVAMED's spinal portfolio includes PEEK interbody fusion cages and cervical cages alongside its pedicle-screw and rod systems.

Clinical and Technical Context
Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion. Cranial implant material is chosen in part for imaging compatibility and low profile, with platinum and titanium being common options. INVAMED's spinal portfolio includes PEEK interbody fusion cages and cervical cages within its neuro, spine, and cranial line. INVAMED's neuro and spine FAQs describe percutaneous disc decompression using minimally invasive mechanical or radiofrequency techniques for contained herniations. INVAMED's Stella Cranial Platinum Plate is a platinum-based cranial plate offered within the cranial fixation line. In the spine, pedicle screw and rod systems provide rigid fixation to stabilize segments, correct alignment, or support fusion. INVAMED lists intraoperative neuromonitoring among the tools in its neuro, spine, and cranial portfolio. All INVAMED neuro, spine, and cranial implants are intended for use by trained neurosurgical and spine surgical teams and per the IFU. The construct length and screw placement are planned and executed by the operating spine surgeon. 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. INVAMED's Stella Cranial Platinum Plate is a platinum cranial plate used for craniotomy closure, skull reconstruction, and neurosurgical fixation, described with a 3D-technology patient-anatomy fit.
