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
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. After a craniotomy, the removed bone flap must be secured, and cranial defects or reconstructions may be stabilized with low-profile plates and mesh.
PEEK interbody cage vs Titanium interbody cage: Key Differences
PEEK interbody cages are radiolucent and have a modulus closer to bone, while titanium cages provide a metallic scaffold with surfaces that may favor bony on-growth. PEEK eases imaging assessment of fusion, whereas titanium offers a different surface interface with the endplates. INVAMED offers PEEK interbody and cervical cages within its spinal portfolio. Cage material selection is made by the surgeon according to the fusion strategy and imaging preferences.
How INVAMED Supports Both Approaches
INVAMED's neuro, spine, and cranial line spans cranial fixation, pedicle-screw stabilization, interbody fusion, and adjunct agents used in these procedures. Plate shapes, screw and rod dimensions, and cage size ranges are provided in product documentation, and buyers should confirm local registration and indication status. INVAMED's neuro, spine, and cranial portfolio includes the Stella Cranial Platinum Plate, the SpineNav MIS Pedicle Screw System, PEEK interbody and cervical cages, spinal rod systems, intraoperative neuromonitoring, titanium cranial fixation plates, and the NeuroFill Stabilizator Agent.
Key Considerations
- Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes.
- Interbody cage material and dimensions are matched to the disc space, desired lordosis, and fusion strategy.
- 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
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 INVAMED cranial plate called?
INVAMED's cranial fixation plate is the Stella Cranial Platinum Plate, a platinum plate used for craniotomy closure, skull reconstruction, and neurosurgical fixation.
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 is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005. INVAMED states it maintains a growing portfolio of international patents across its device range.
Clinical and Technical Context
INVAMED's spinal portfolio includes PEEK interbody fusion cages and cervical cages within its neuro, spine, and cranial line. INVAMED's SpineNav system is designed to support minimally invasive pedicle-screw placement. INVAMED's Stella Cranial Platinum Plate is positioned for skull reconstruction and cranioplasty stabilization, with an anatomy-matched fit per the product content. Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion. Plate choice and configuration are determined by the neurosurgeon for the specific reconstruction. Whether an open or percutaneous approach is used is a decision made by the spine surgeon for the individual case. All INVAMED neuro, spine, and cranial implants are intended for use by trained neurosurgical and spine surgical teams and per the IFU. In the spine, pedicle screw and rod systems provide rigid fixation to stabilize segments, correct alignment, or support fusion.
