Interbody cages or spacers are often used to treat patients with Degenerative Disc Disease (DDD). Existing designs used without fixation are subject to migration and even small movements may create challenges for promoting bony growth for fusion. Current designs with integrated fixation or used with additional plating may: be cumbersome, be time-consuming to deploy, require increased retraction, and increase operative time.
Lateral lumbar interbody fusion (LLIF) is a well-established and proven method for treatment of DDD. The patent pending VerteLP implant design addresses a number of the problems observed in other lateral systems.
- Fixation – Fixation of an interbody cage inhibits migration1
- Minimally Invasive – In-line deployment of lateral plating minimizes retraction size and time
- Elegant – Streamlined instrumentation requiring only 3 instruments to insert the cage and deploy the lateral plating
- Biomechanics – First of its kind bilateral plate fixation limits axial rotation and lateral bending, increasing stability of the segment
- OR Efficiency – Reduction in OR time due to fewer instruments and surgical steps required to insert cage and lateral plating when compared to other lateral systems
- Anatomy Preserving – Unlike competitive systems, the VerteLP lateral plating fixation does not compromise the endplates or vertebral bodies
- Avoids Pedicle Screws – VerteLP lateral plating does not interfere with the placement of pedicle screws in primary cases or at adjacent levels where prior hardware is in place
