Intervertebral Disc Prostheses with Dynamic Stabilisation at Asklepios Clinic St. Georg

At the Asklepios Clinic St. Georg in Hamburg, we advocate for a "motion-first" philosophy in spinal surgery. While traditional fusion (spondylodesis) aims to stop movement to treat pain, our specialized spine team focuses on intervertebral disc prosthetics and dynamic stabilisation. These advanced techniques are designed to replicate the natural biomechanics of a healthy spine. By replacing a degenerated disc with a functional implant or supporting the vertebrae with flexible systems, we protect the neighboring spinal segments from the "domino effect" of premature wear often seen after rigid fusions. The surgical core of our motion-preservation program is the total disc replacement, primarily utilized in the cervical and lumbar spine. Unlike a bone graft that turns two vertebrae into a single block, a disc prosthesis consists of high-tech metal plates with a mobile plastic core that allows for sliding, rotation, and cushioning. At St. Georg, we use 3D-fluoroscopic navigation to ensure the prosthesis is centered with mathematical precision. This alignment is critical; even a millimeter of deviation can affect how the spine carries weight. By restoring the natural height and mobility of the disc space, we immediately decompress pinched nerves while allowing you to maintain a full, natural range of motion in your neck or lower back. For patients who require extra support but still wish to avoid a "stiff" back, we offer dynamic stabilisation systems. These involve the use of flexible rods or "tension bands" instead of rigid titanium bars. These implants act like an internal brace or a shock absorber for the spine. They limit excessive, painful movements while still allowing the treated segment to move within a safe, physiological range. This is particularly effective for "Early Degenerative Instability," where the spine needs help carrying the load, but the joints are not yet so damaged that they require permanent locking. Safety and precision at St. Georg are governed by our Level I Spine Center certification, the highest achievable standard in Germany. During the implantation of disc prostheses, we utilize high-power surgical microscopes and real-time electromyography (EMG) monitoring. This ensures that as we navigate the anterior (front-side) approach to the spine, moving past vital blood vessels and nerves to reach the disc, we have a clear, magnified view and constant feedback on nerve health. This meticulous approach minimizes tissue trauma and is the reason our patients often report a "more natural" feeling in their back compared to traditional fusion patients. Our technical infrastructure for motion-preserving spine surgery includes:Prosthetic Innovation. Latest-generation M6, ProDisc, or activL implants designed for multi-axial movement. Dynamic Hardware. Flexible stabilization systems such as the DYNESYS or similar ligament-replacement technologies. Surgical Navigation. Medtronic StealthStation for precise 3D-positioning of motion-preserving hardware. Vascular Support. Close collaboration with our vascular surgery department for safe anterior access to the lumbar spine. The recovery course at St. Georg is uniquely tailored to the "active" nature of these implants. Because the goal is motion, our specialized physiotherapists begin functional mobilization within 24 hours of surgery. You will be guided through specific movements that "teach" your muscles how to interact with the new prosthesis or dynamic stabilizer. The inpatient stay typically lasts between five and seven days. One of the greatest advantages of these techniques is that they rarely require a hard brace after surgery, allowing for a much faster return to work, sports, and social life.
