Decide with confidence: 5 questions you should ask:
Can I expect complete mobility again?
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.
When is the right time for surgical intervention?
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
Which brands/types of implants do you use, and why?
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.
Have the implants been extensively tested and researched?
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.
Should I rather trust a senior neurosurgeon or an orthopedic surgeon?
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.

Cervical motion preserving technology – alternative to spinal fusion
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 Synergy
ONZ neurosurgeon Dr. Bernd Illerhaus about Synergy
The Synergy Disc is our viable alternative to fusion in patients with pre-operative alignment issues. It is available in many different sizes and configurations. It is our preferred implant type in case of kyphotic misalignments and by this restoring sagittal balance and preserving vertebral motion.
Different anatomies require different implant solutions. Principally we target to replace the pathomorphologic disc by an artificial disc that mimics the biostatical features of a natural, healthy disc. In patients with very low discal heights we have to react with the smallest implant types available.
