How the
Baguera® L Disc
Restores Natural Motion
The Baguera® L Disc’s advanced mobile core is designed to provide smooth and controlled motion, restoring spinal biomechanics and disc height. Its anatomically optimized endplates are coated with plasma-sprayed titanium and hydroxyapatite to enhance long-term bone integration and implant stability.
Who Can Benefit
from the Baguera® L Disc?
Degenerative Disc
Disease (DDD)
Loss of disc integrity, leading to pain and instability. The Baguera® L Disc is designed for single or two-level DDD between L3 and S1.
Chronic Discogenic
Back Pain
Severe, ongoing pain caused by disc degeneration, not improved through conservative management.
Motion-Preserving Alternative
Patients who need lumbar spine stabilization and dynamic motion recovery instead of undergoing spinal fusion.
Why Choose
the Baguera® L Disc?
With its mobile core and optimized endplates, the Baguera® L Disc provides dynamic performance, restoring natural motion and improving long-term spinal stability. It offers enhanced protection for adjacent segments compared to traditional fusion techniques.
Advanced Motion Mechanics
The Baguera® L Disc supports multidirectional motion, including flexion, extension, lateral bending, and axial rotation, allowing for natural and smooth movement across the affected spinal segments.
ESP® Disc
Precision Through Innovation
Innovative shock absorption and multidirectional mobility – the ESP® Disc protects adjacent segments, preserves spinal function, and enhances recovery

Key Features of the
ESP® Disc
Dynamic Shock Absorption
Featuring a viscoelastic elastomer core, the ESP® disc mimics the natural intervertebral disc by providing multi-directional mobility and energy absorption. Superior elasticity reduces stress on adjacent segments.
Reliable Stability and Integration
Coated with a unique titanium surface to promote bone integration and long-term fixation.
Customizable sizes to accommodate diverse anatomies.
Customizable sizes to accommodate diverse anatomies.
Clinical Versatility
Ideal for both single-level and multi-level lumbar degenerative disc disease (DDD).
Proven to reduce chronic pain and preserve functional range of motion.
Proven to reduce chronic pain and preserve functional range of motion.
How the ESP® Disc Restores Mobility
The ESP® Disc’s core is made of viscoelastic elastomer material designed to replicate the natural function of intervertebral discs. This allows for dynamic shock absorption and smooth motion in all directions. The titanium-coated endplates ensure secure integration with surrounding bone, providing a stable yet flexible solution for degenerative disc conditions.
Who Can Benefit
from the ESP® Disc?
Degenerative Disc
Disease (DDD)
Progressive degeneration of spinal discs that causes pain, stiffness, and limited motion. The ESP® Disc is ideal for both single-level and multi-level DDD between L3 and S1.
Chronic Discogenic
Back Pain
Persistent back pain originating from damaged spinal discs, unresponsive to conservative treatments for six months or more.
Motion-Preserving Alternative
Patients seeking to avoid spinal fusion and maintain natural spinal movement while reducing pain.
Why Choose the ESP® Disc?
Compared to traditional fusion procedures, the ESP® Disc offers a faster recovery and improved long-term mobility by preserving natural spinal movement and reducing stress on adjacent segments.
Dynamic Shock Absorption at Its Best
The ESP® Disc enables smooth motion across multiple axes, including flexion, extension, lateral bending, and axial rotation.
