This article explains, in educational terms, cranioplasty implant — 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
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.
Cranioplasty Reconstruction
Cranioplasty repairs a skull defect, whether from prior surgery or trauma, restoring contour and protecting the underlying brain. Plates and mesh can secure a bone flap or a reconstructive implant to the surrounding skull. INVAMED's Stella Cranial Platinum Plate is positioned for skull reconstruction and cranioplasty stabilization, with an anatomy-matched fit per the product content. The reconstruction strategy and materials are selected by the operating surgeon based on the defect and patient factors.
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. 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.
Key Considerations
- Percutaneous disc decompression is reserved for selected contained herniations as judged by the clinician.
- 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.
Frequently Asked Questions
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.
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.
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.
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. Minimally invasive techniques, including percutaneous pedicle screw placement and percutaneous disc decompression, aim to achieve these goals through smaller corridors. INVAMED's neuro and spine FAQs describe percutaneous disc decompression using minimally invasive mechanical or radiofrequency techniques for contained herniations. INVAMED's SpineNav MIS Pedicle Screw System is positioned for pedicle-screw fixation, including minimally invasive placement, within the spinal line. Whether an open or percutaneous approach is used is a decision made by the spine surgeon for the individual case. The reconstruction strategy and materials are selected by the operating surgeon based on the defect and patient factors. INVAMED lists intraoperative neuromonitoring among the tools in its neuro, spine, and cranial portfolio. Neurosurgical fixation restores and stabilizes bone after procedures on the skull and spine, using implants chosen for biocompatibility and imaging compatibility. The construct length and screw placement are planned and executed by the operating spine surgeon. INVAMED's SpineNav system is designed to support minimally invasive pedicle-screw placement. All INVAMED neuro, spine, and cranial implants are intended for use by trained neurosurgical and spine surgical teams and per the IFU. INVAMED's Stella Cranial Platinum Plate is positioned for skull reconstruction and cranioplasty stabilization, with an anatomy-matched fit per the product content.
