InterSpinousSystem (ISS)
The ISS is a dynamic system, without pedicular screws or ligament, allowing distraction and compression. It is especially designed to be inserted between two spinous procseses at the lumbar spinal level. By maintaining the distraction between the two adjacent processes, it further allows conservation of inververtebral movements at the spinal segment level.
Materials:
Titanium Alloy (Ti6AI4V) allowing for a definite rigidity and a certain amount of elasticity.
Sizes:
8-16mm
Surgical Procedure:
The spinal collumn is revealed and then the implant is fixed to the desired two spinal processes.
The arms of the interspinous system have to be adjusted between the spinous processes.
The fixation pins are inserted into the especially designed instrument and positioned in front of the conique holes of the implant.
The fixation is finalized by the conical adjustment pin - stabilizer and by the fact that the pin engages 2 mm into the spinous process.
Indications:
- Primary degenerative disc disease (with or without herniation)
- Resistant to conservative therapies
- Lumbar spinal instability
- Secondary post-decompressive discopathies
- Central and lateral spinal stenosis
- Facetal arthrosis
Effect:
- Maintains and protects the invertebral disc height
- Puts the disc at rest
- Treats the pain
- Allows rehydration of degenerative disc
- Redistributes discal lodes
Studies:
None known.
Success Rates:
There is no study of this device's success in treating lumbar spinal stenosis.
