Decide with confidence.
5 questions you should ask.

Can I expect complete mobility again?
When is the right time for surgical intervention?
Which brands/types of implants do you use, and why?
Have the implants been extensively tested and researched?
Should I rather trust a senior neurosurgeon or an orthopedic surgeon?
Regaining complete mobility is always the goal. The repair of the diseased spinal segments often results in an even better mobility. Our patients greatly benefit from short recuperation, returning to work or other activities earlier and have significantly less future problems like adjacent level disease.
A surgery is principally the last resort. However, particularly in the cervical spine early intervention is often advisable in order to prevent neurological deficits and multi-level degeneration.
When it comes to quality and applicability, not all implant types come into question. In fact, there are special criteria that demand diligent differentiation during the indication process, e.g. your individual pathology or anatomy. Understanding how and why the indications may differ is important and something to discuss with your senior surgeon.
In Germany, all medical devices (which includes spinal implants) must have undergone extensive scientific evaluation and have a proven track record. Using nonfusion technology, Germany has a long tradition of over 25 years. We only use surgical techniques that have been approved by the German authorities and provide an advantage to other methods.
ONZ spine department is a neurosurgical center specialized in spine. Our vertebrate spinal column provides intrinsic protection to the neural elements. Most spine diseases involve nerval structures including stenosis, disc herniations, adhesions, and scar tissue. Surgical solutions belong in the hands of experienced neurosurgeons. Principally, also orthopedic surgeons can specialize in lumbar spine surgery (as opposed to cervical interventions which are merely the field of neurosurgery) if surgeons are meticulous and precise.

ONZ neurosurgeon Dr. Thomas Bierstedt about ESP disc.

The ESP disc prosthesis is made of 2 titanium alloy end-plates and an elastomeric cushion. The spikes on the end-plates outer surfaces improve primary fixation. The combination of a hydroxyapatite (HA) coating on top of a T40 rough surface are considered as one of the best existing coating. The titanium alloy used for the end plates allows clear medical imaging and guarantees good bony fixation over time.

Implant type ProDisc C Nova

ONZ neurosurgeon Dr. Bernd Illerhaus about ProDisc C Nova and ProDisc C Vivo.

Let me introduce you our two advanced disc implants: ProDisc C Nova and ProDisc C Vivo. ProDisc C Nova is a cutting-edge implant designed to restore natural movement in the cervical spine. It offers a wide range of motion, allowing flexibility and stability while reducing the risk of adjacent segment degeneration. With its innovative design and proven clinical outcomes, ProDisc C Nova provides an effective solution for patients seeking long-term relief from disc-related issues.

On the other hand, ProDisc C Vivo is a dynamic cervical disc implant that mimics the natural disc's shock-absorbing function. It promotes spinal alignment, reduces pain, and allows for controlled motion. ProDisc C Vivo offers a unique combination of durability, stability, and anatomical compatibility, enabling patients to regain their mobility and improve their quality of life.
