This article explains, in educational terms, percutaneous disc decompression — how the technology works and where it fits. After a craniotomy, the removed bone flap must be secured, and cranial defects or reconstructions may be stabilized with low-profile plates and mesh. 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
After a craniotomy, the removed bone flap must be secured, and cranial defects or reconstructions may be stabilized with low-profile plates and mesh. 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.
Percutaneous Disc Decompression
Percutaneous disc decompression uses minimally invasive mechanical or radiofrequency techniques to reduce intradiscal pressure in contained disc herniations. By removing or modifying a small volume of disc material, the aim is to relieve pressure contributing to symptoms in selected patients. INVAMED's neuro and spine FAQs describe percutaneous disc decompression using minimally invasive mechanical or radiofrequency techniques for contained herniations. Whether a patient is a candidate for disc decompression is determined by the treating clinician.
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. Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes. 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.
- Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes.
- 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.
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
INVAMED's SpineNav system is designed to support minimally invasive pedicle-screw placement. Whether a patient is a candidate for disc decompression is determined by the treating clinician. The choice of material for a given patient is made by the neurosurgeon in line with the device labeling. Cage material, size, and lordosis are selected by the surgeon according to the disc space and fusion goals. INVAMED's SpineNav MIS Pedicle Screw System is positioned for pedicle-screw fixation, including minimally invasive placement, within the spinal line. 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. Manufacturer descriptions, such as an anatomy-matched cranial plate fit, reflect design intent rather than guaranteed outcomes. INVAMED's Stella Cranial Platinum Plate is a platinum-based cranial plate offered within the cranial fixation line. Cranial implant material is chosen in part for imaging compatibility and low profile, with platinum and titanium being common options. The use and interpretation of monitoring are handled by the surgical and monitoring team. Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion.
