This article compares two approaches side by side to clarify how they differ in principle and practice. Neurosurgical fixation restores and stabilizes bone after procedures on the skull and spine, using implants chosen for biocompatibility and imaging compatibility. 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
In the spine, pedicle screw and rod systems provide rigid fixation to stabilize segments, correct alignment, or support fusion. 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.
Titanium cranial implant vs PEEK cranial implant: Key Differences
Titanium cranial implants are metallic and durable with established biocompatibility, while PEEK implants are radiolucent and have a stiffness closer to bone. Titanium can produce imaging artifact but is strong and thin, whereas PEEK reduces artifact and can be shaped for larger defects. INVAMED's cranial line features the platinum-based Stella plate for fixation and reconstruction. Material choice for a cranial reconstruction is made by the neurosurgeon based on the defect and imaging needs.
How INVAMED Supports Both Approaches
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Key Considerations
- All INVAMED neuro, spine, and cranial implants are intended for use by trained neurosurgical and spine surgical teams and per the IFU.
- Cranial implant material is chosen in part for imaging compatibility and low profile, with platinum and titanium being common options.
- 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.
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.
About INVAMED
INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development. INVAMED states it maintains a growing portfolio of international patents across its device range.
Clinical and Technical Context
INVAMED's neuro and spine FAQs describe percutaneous disc decompression using minimally invasive mechanical or radiofrequency techniques for contained herniations. The use and interpretation of monitoring are handled by the surgical and monitoring team. INVAMED's spinal portfolio includes PEEK interbody fusion cages and cervical cages within its neuro, spine, and cranial line. All INVAMED neuro, spine, and cranial implants are intended for use by trained neurosurgical and spine surgical teams and per the IFU. Neurosurgical fixation restores and stabilizes bone after procedures on the skull and spine, using implants chosen for biocompatibility and imaging compatibility. INVAMED's SpineNav system is designed to support minimally invasive pedicle-screw placement. Whether an open or percutaneous approach is used is a decision made by the spine surgeon for the individual case. INVAMED's Stella Cranial Platinum Plate is positioned for skull reconstruction and cranioplasty stabilization, with an anatomy-matched fit per the product content.
