The Cervical Prosthesis


The CP-ESP cervical disc prosthesis has been developped to mimic the natural cervical disc and allow the spine to behave as if the replaced disc would be natural in all situations.




  • Heights from 5mm to 7mm
  • Benefits from over 10 years of development
  • 6 degrees of freedom
  • Adaptive center of rotation
  • No surface bearing for increased lifetime
  • Improved stability
  • Shock absorbing

The engineering behind the CP-ESP

Structure of the natural cervical disc

  • Inner core (nucleus pulposus)
  • Outer core (annulus fibrosis)

Structure of the CP-ESP® cervical prosthesis

  • Titanium endplates and hydroxyapatite coating
  • Inner and outer core (Polycarbonate urethane)

Six degrees of freedom restore your “natural” mobility

  • Lateral flexion
  • Vertical translation
  • Lateral translation
  • Flexion/extension
  • Anterior-posterior translation
  • Axial rotation


Indications for use

The CP-ESP cervical disc prosthesis is designed for specific indications detailed in the sales literature, such as:

Symptomatic cervical discopathy, defined as (radicular) pain and/or a functional/neurological deficit in the neck the arm with at least one of the following pathologies    confirmed by imaging (computerized tomography, MRI or radiography) and having resisted medical treatment for at least 6 months.

  • Herniated nucleus pulposis
  • Spondylitis (defined by the presence of osteophytes)
  • Radicular compression
  • Discal hernia
  • Nerve compression

Designed to reproduce natural properties

 Natural Disc
Flexion(A/P) & Extension 7°/7°7°/7°
Lateral inclination 6°/6°5°/5°
Axial rotation 4°/4°3.5°/3.5°


Surgical procedure

The procedure is performed under general anesthesia. An x-ray is taken in order to precisely determine and mark the correct vertebral level and the site for accessing the cervical spine.

After entering the space, your surgeon will remove the deteriorated disc, remove residual tissue from the disc space and relieve the nerve exit openings and the spinal canal of any pressure. In just a few steps, the ideal size and height of the new plastic disc is measured and then the surgeon places the final implant with image guidance.

Once the CP-ESP® has been implanted, another x-ray is performed in order to ensure that the prosthesis is seated properly and is at the right level in the disc compartment. The wound is then closed and after a short recovery period, you can start resuming your regular activities and return to your everyday routine. After the surgery, your surgeon will give you advice about resuming activities and for follow-up care. For you as the patient, after a just short hospital stay, there’s nothing stopping you from returning to a symptom-free normal life.

Recovery and a relaxed life after the procedure.
