With the C Disc cervical prosthesis, Cousin Surgery strengthens its range of implants dedicated to preserving mobility

Cousin Surgery, a major player in implantable medical devices, is expanding its spine surgery offering with the acquisition of C Disc, the first inverted cervical prosthesis with a dual centre of rotation. The innovative design and exclusive biomechanical performance of this implant help surgeons preserve and control mobility of the cervical segment in their patients.
C Disc therefore offers an attractive alternative to fusion and represents a major technological advance, meeting a wide range of surgical indications.
C Disc naturally complements the range of implants developed by Cousin Surgery for spine surgery, with the same objective as always: helping surgeons preserve their patients’ mobility.

C Disc is a cervical prosthesis indicated for the treatment of disc degeneration and various instabilities of the cervical spine (disc herniation, disc protrusion with spinal canal stenosis and mild to moderate spondyloarthrosis).

C Disc is designed both to preserve and control patients’ cervical mobility and to provide surgeons with a high level of implantation safety.

C Disc: advanced technology to preserve patient mobility

  • Dr. Jean-Philippe Lemaire, orthopaedic surgeon and pioneer in disc prostheses
  • Prof. François Lavaste, Emeritus Professor at Arts et Métiers ParisTech, biomechanics specialist

C Disc has therefore benefited from extensive clinical experience and the unique scientific expertise of the George Charpak Institute of Human Biomechanics.

Its innovative design offers unique biomechanical features on the market, helping to preserve patient mobility.

Mobile-core “Ball and Socket” design

The prosthesis features a mobile core made of High-Density Polyethylene (HDPE), which adapts to the physiological movements of the cervical spine: flexion/extension, lateral bending, rotation and translation.

Self-centring and limitation of extreme movements

The implant design incorporates a dual centre of rotation that ensures optimal self-centring of the prosthesis and limits excessive movements.

Implantation safety

The C Disc prosthesis also brings innovation in terms of implantation: it is supplied pre-assembled with a single-use insertion instrument, enabling optimal handling and repositioning of the implant without disconnection.

“Made in France” manufacturing quality

C Disc prostheses are entirely manufactured and assembled in France. They benefit from unique know-how in the production of high-technology spinal implants.

Objective: to complete the range of implants dedicated to spine surgery

The launch of the C Disc prosthesis enriches Cousin Surgery’s offering in the field of spine surgery and mobility preservation, notably marked by alternatives to fusion:

  • Intraspine: a device dedicated to the interspinous space with laminar support, respecting lumbar biomechanics
  • Bdyn: an implant dedicated to posterior dynamic stabilisation, in cases of degeneration and/or spinal instability.

C Disc is already available in several European markets (France, Germany, Spain and the United Kingdom). International rollout will then target Vietnam, Korea, Taiwan and Mexico.

Our objective has always been to offer surgeons the most relevant solutions to help preserve their patients’ mobility.
With C Disc, we are complementing our expertise in spine surgery with an innovative alternative offering for the cervical segment.
