LISA™ Lumbar Implant for Stiffness Augmentation

A minimally invasive solution, preserving mobility & restoring function.

Posterior dynamic stabilisation system

The LISATM Posterior Dynamic Stabilization System is indicated for low-back pain that accompanies degenerative lesions of grade II, III and IV (Pfirrmann MRI classification), unresponsive to conservative care treatment. It provides an adequate solution to treat the root cause of the Degenerative Disc Disease instability, without the need to fuse the vertebrae.

It can be used in up to two adjacent levels from L1 to L5.

LISA is CE certified under EU MDR by the notified body BSI.

Clinical applications:

  • Massive herniated disc in young adults;
  • Recurrent disc herniation or herniated disc accompanying an L5 sacralization transitional anomaly, treated by discectomy;
  • Degenerative disc disease at a segment adjacent to a fusion;
  • Degenerative lesions with or without Modic 1; and
  • Lumbar canal stenosis treated by decompression.

The LISA is a 3rd generation dynamic stabilization device which was invented in 1986 and is based on 35 years of clinical research.

Clinical benefits

  • LISA stabilizes the motion segment by controlling flexion and extension at the operated level. 1

  • LISA preserves motion and anatomy 1

  • LISA protects adjacent level kinematics from extraordinary stress and degeneration 1

  • Off-loads the disc and facet joints and respects sagittal balance through preservation of lumbar lordosis 1

  • Minimally Invasive procedure 2

  • LISA is fully & easily reversible 1

LISA stabilises the vertebral segments while preserving natural mobility, restores the sagittal balance of the spine while preserving lumbar lordosis, and frees up neurological structures.

LISA™ Lumbar Implant for Stiffness Augmentation

LISA resolves the undertreatment / overtreatment dilemma for Lumbar Stenosis and Degenerative Disc Disease by providing a suitable alternative to:

  • Decompression alone which may further destabilize the segment
  • Irreversible fusion procedure, when the lumbar disc is not entirely degenerated

Materials

  • A PEEK intervertebral spacer
  • A polyester band
  • A titanium blocker

Clinical Data

  • Based on over 30 years of clinical research.
  • Post-marketing clinical study involving 137 patients in 5 European centres.

Use

  • Adapted to the patient’s morphology thanks to its 4 available sizes
  • Can be used on 1 or 2 levels depending on clinical needs
  • Dedicated instrumentation for a precise and minimally invasive procedure
