LP-ESP – Lumbar prosthesis


The ESP prosthetic disc is the result of 10 years of collaborative research work at the Hôpital Pitié Salpêtrière in Paris, the French Atomic Energy Commission (CEA) and the Université Paris VI, and was driven by the Oséo Innovation contest in France.

It consists of two titanium alloy plates and an elastomer pad. The pins on the outer surfaces of the plates facilitate primary fixation.

The ESP prosthetic disc restores the mechanical properties of the intervertebral disc and in particular its damping properties

Over 10 years of research and development
• 10 years of follow up (since 2004)
• 6° of freedom
• Primary stability thanks to spikes allowing the prosthesis to be
implanted anteriorly as well as antero-lateraly and to face difficult soft
tissue situations
• Adaptive center of rotation
• No surface bearing for an increased lifetime
• Improved stability
• Shock absorbing
• Designed to fit and restore patient lordosis

The development of the ESP disc range originally came from Professor Roy
Camille, from La Pitié Salpétrière Teaching Hospital in Paris (France). After
inventing the pedicle screw which became the gold standard for Spine fusions,
Pr. Roy Camille started to work on analysing the natural disc properties and
designed a prosthesis to restore these.

  • Lumbar discopathy that is resistant to medical treatment
  • Lumbar discopathy disease after treatment of a herniated disc
  • Radiculopathy by a recurrence of a disc hernia
    (except for excluded hernias)

Between the 2 titanium end-plates the elastomeric parts are injected for
controled resistance to compression, flexion and rotation. These elastomeric
parts are concentric and their fixation prohibits micro motion. The materials
used for the implants have been tested for biocompatibility according to the
ISO standard 10993.
• Minimally invasive anterior approach which allows reduced hospital stay and
improves rehabilitation
• LP-ESP tested up to 40 million cycles
• ESP should give a significant reduction in pain severity, re-establish lumbar
curvature and natural disc functions
• ESP allows quick return to normal daily activities
