This article explains, in educational terms, minimally invasive pedicle screw — how the technology works and where it fits. Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion. 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. Neurosurgical fixation restores and stabilizes bone after procedures on the skull and spine, using implants chosen for biocompatibility and imaging compatibility. Interbody fusion cages, often made of PEEK or titanium, are placed between vertebral bodies to restore disc height and promote bony fusion.
Minimally Invasive Pedicle Screw Placement
Minimally invasive, or percutaneous, pedicle screw placement inserts screws through small incisions, often with fluoroscopic or navigation guidance. The approach aims to reduce soft-tissue disruption compared with a traditional open exposure. 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.
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. 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.
Key Considerations
- Interbody cage material and dimensions are matched to the disc space, desired lordosis, and fusion strategy.
- 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.
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.
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.
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.
Clinical and Technical Context
INVAMED's neuro and spine FAQs describe percutaneous disc decompression using minimally invasive mechanical or radiofrequency techniques for contained herniations. Whether an open or percutaneous approach is used is a decision made by the spine surgeon for the individual case. Pedicle-screw trajectory accuracy is important to remain within the bony pedicle, motivating the use of fluoroscopy or navigation. Plate choice and configuration are determined by the neurosurgeon for the specific reconstruction. INVAMED's Stella Cranial Platinum Plate is positioned for skull reconstruction and cranioplasty stabilization, with an anatomy-matched fit per the product content. 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. Interbody cage material and dimensions are matched to the disc space, desired lordosis, and fusion strategy. The use and interpretation of monitoring are handled by the surgical and monitoring team. INVAMED's SpineNav MIS Pedicle Screw System is positioned for pedicle-screw fixation, including minimally invasive placement, within the spinal line. Cranial implant material is chosen in part for imaging compatibility and low profile, with platinum and titanium being common options. The construct length and screw placement are planned and executed by the operating spine surgeon.
