Motion Preservation - Artificial Disc & Dynamic Stabilization
A leader in motion preservation surgery and artificial disc replacement, Dr. Anand strives to provide safe and effective advances in spine surgery. Dr. Anand and trained staff deliver a caring approach to ensure patients the highest standards in spine care and treatment.
The following are among the top motion preservation devices used by Dr. Anand.

Stabilimax NZ Dynamic Spine Stabilization System
The Stabilimax NZ Dynamic Spine Stabilization System, a device designed to provide stabilization while allowing for
motion, is now being clinically evaluated.
With aging (or as a result of injury or damage to the lower back), some degeneration of the skeletal and muscular structures of the lumbar area of the spine occurs. This degenerative process creates instability in the spine and a narrowing of the spinal canal, or spinal stenosis. As the narrowing occurs, and as the body tries to compensate, there is compression of the nerve roots, which causes the pain associated with spinal stenosis.
Stabilimax NZ is designed to offer a unique treatment for spinal stenosis called "dynamic stabilization." This means that while Stabilimax NZ works to stabilize the affected area of the spine, it does so in a manner which preserves both bending and twisting motions.

NeoDisc™ Cervical Disc Replacement
Advancing motion preservation through soft fixation. The combined elastic material and embroidery technology of NeoDisc™ provides a variety of surgical options, including interbody and ligamentous, in motion preservation applications.
NeoDisc™ consists of three parts:
- A solid silicone core, containing no silicone gel, that acts like a cushion similar to a normal intervertebral disc.
- An encapsulating jacket formed from a polyester textile which is manufactured using computer controlled embroidery technology.
- Standard titanium alloy bone fixation screws.
- NeoDisc is designed to allow for motion maintenance at the surgical site.
- NeoDisc is fully imaging compatible, so it will not interfere with your surgeon’s examination of the implant.
- NeoDisc’s materials have proven, positive clinical results for use in orthopaedic implant applications.
- The NeoDisc surgical procedure is similar to the anterior cervical discectomy and fusion (ACDF), a very familiar surgery to your doctor.
DIAM™ Spinal Stabilization System
Through a small incision, the DIAM™ System implant is inserted between two spinous processes to stabilize the spine. The spinous process is the portion of the vertebrae that protrudes from the back of the spinal column. They create the "bumps" that you can feel along the middle of your back.
The core of the DIAM™ System implant is made of silicone. The outer mesh and tether are made of polyethylene terephthalate (polyester). The crimp is titanium. The device is available in a variety of sizes to allow the surgeon to accommodate the patient's individual anatomy.
Today, over 12 million people will seek medical attention from a doctor for symptomatic spinal degenerative disease and undergo one or more non-operative therapies to alleviate their pain and restore health to their spine.
History of the DIAM™ Spinal Stabilization System
- Fourteen different published European studies with 527 patients
- More than 27,000 current DIAM™ System patients in Europe
- To participate in the clinical trial, you must meet the following criteria:
- Degenerative disc disease at single level between L2-L5
- Between 18-70 years of age
- At least 6 weeks of non-operative treatment prior to enrollment
- Not pregnant or planning a pregnancy during the study
- Willing and able to participate in either of the randomized treatments for the duration of the study follow up period.
- All potential candidates are subject to the above and additional non-listed clinical trial criteria.
Charite Artificial Disc
To treat degenerative disc disease, doctors usually begin with a conservative (nonsurgical) medical treatment. When conservative therapy fails, other approaches, possibly including surgery, may be recommended. Currently, the gold standard for surgical treatment of problematic degenerative disc disease is spinal fusion. This procedure attempts to permanently lock two or more spinal vertebrae together so they cannot move except as a single unit. This may alleviate pain in a motion segment. Spinal fusion, however, has well known potential disadvantages, including:
- Loss of motion and flexibility
- Permanently altered motion characteristics and biomechanics
- Potential for accelerated degeneration of the discs both above and below the fused level that can lead
- to more pain and the need for more surgery
Artificial disc replacement offers a reversible, viable alternative to fusion that potentially avoids the accepted shortcomings of fusion. By inserting an artificial disc instead of performing spinal fusion, there is the possibility of reducing damage to nearby discs and joints. This is because artificial disc replacement allows for motion preservation, near normal distribution of stress along the spine and restoration of the pre-degenerative disc height.

Dynesys Spinal Stablization System
Unlike a fusion, which alleviates pain by stopping motion at the affected area of the spine, the Dynesys System uses flexible materials to stabilize the affected region of the lumbar spine while preserving the natural anatomy and movement of the spine.
When an unfortunate event known as spinal stenosis occurs, compressed nerves cause pain when bending in certain directions. The Dynesys system helps stabilize the affected region of the spine enabling regular movement without needless pain and suffering.
The procedure involves attaching a small device to both sides of the ailing vertebrae. The device itself consists of external spacers made of flexible plastic tubes surrounding a thin cord. Once implanted the device stabilizes the joints, allowing the vertebrae to assume a more natural position while leaving the other discs and joints intact. This causes the pain to completely dissipate.

PCM Artificial Disc
The PCM (Porous Coated Motion) Artificial Disc is another system that is now being used to preserve natural motion without fusion. This device is often used in the Cervical or neck portion of the spine. The PCM Artificial Disc is designed to replace the diseased disc and provide support for the vertebrae while at the same time, preserving its natural function.
The PCM implant is comprised of upper and lower endplates made with a special material called cobalt chrome alloy. The metal endplates are bonded to the vertebrae, and the area between the two endplates acts like a ball and socket, allowing the upper half to slide and rotate forward and backward. The procedure is minimally invasive. Only a small incision is made in the front of the neck and the damaged disc is removed along with any other tissue that is compressing the nerve. The edges of the bones are shaped to ensure a proper fit and the PCM Artificial Disc is inserted in the disc space. The procedure generally takes between 1-2 hours and the patient is typically discharged by the following day.
Candidates considered for participation in the PCM Cervical Artificial Disc clinical trial must have a diagnosis of cervical radiculopathy or myelopathy, be able to return for study follow-up appointments for at least two to five years, and be nonresponsive to stimulation, chiropractic care, etc.

Kyphoplasty
Kyphoplasty is a minimally invasive treatment developed to treat vertebral compression fractures in the spine. Compression fractures in the spine, sometimes cause back pain, even in making simple movements such as walking and lifting. Severe cases of vertebral compression fractures (VCF) could potentially alter the shape of the spine. The Kyphoplasty treatment is designed to strengthen the spine and possibly eliminate pain by replacing the damaged portion of the vertebral body with special bone cement.
The procedure involves two quarter-inch incisions, through which small tubes that are inserted into the fractured bone. A special balloon is inserted and inflated to straighten the fractured area. The balloon is deflated and then retracted, to allow bone cement to be injected into the cavity the balloon device created. The procedure is normally about 45 minutes per fractured vertebra. The spine is better aligned instantly and pain is relieved immediately after the procedure.
