DIAM
DIAM™ INTERVERTEBRAL PROSTHESIS
Product manufactured by COMPANION SPINE
Device for Intervertebral Assisted Motion for the treatment of moderate low back pain secondary to degenerative disc disease.
Dynamic Stabilisation System
DIAM™ Intervertebral Prosthesis is indicated for Lumbar Surgery
- Arthropathic facet-syndrome.
- Posterior prosthesis for discal assistance.
- Transitional osteosynthesis.
- Foraminal stenosis.
The Diam™ Intervertebral Prosthesis allows an effective stabilization of the operated segments while ensuring a certain flexibility. The purpose of this stabilization is to decrease the lumbagos of the patient while avoiding the arthrodese. The Diam™ Intervertebral Prosthesis is designed for long-term
implantation.
The DIAM™ implant is in clinical use since 1997, and more than 200,000 patients have been successfully treated to date.
Clinical Benefits
- DIAM™ allows balanced load-sharing with painfully overloaded disc, annulus, and facet joints while preserving motion at the treated level. 1,2
- DIAM™ reestablishes supraspinous ligament tension. 1,3
- Controls motion in extension.1,2
- DIAM™ enables tissue-sparing and anatomy preservation.1,4
- Minimally Invasive procedure.4
- Fully and easily reversible.4
Materials
- A silicone implant covered with a woven polyester envelope, designed to be inserted between two adjacent spinous processes of the lumbar spine.
- Polyester strips, secured by titanium crimp rings, hold the device firmly in place.
Clinical Data
- Over 65 articles citing DIAM™ in scientific literature
- Clinical study involving over 100 patients with follow-up over 10 years.
Use
- Adapted to the patient’s morphology thanks to its 5 available sizes
- Can be used on 1 or 2 levels depending on clinical needs
- Ergonomic design for simplified implantation
- Dedicated instrumentation for a precise and minimally invasive procedure
