Spinal fusion may be a solution for some patients with degenerative disc disease who are not candidates for total disc replacement—providing the stability and security needed to help the spine heal.
Spinal fusion is a surgical procedure used to fuse together two or more vertebrae, so they heal into a single bone. For patients with back problems such as degenerative disc disease, fractured vertebra or a herniated disk, the spinal fusion treatment can create invaluable security and eliminate ongoing back pain.
STALIF is an Integrated Interbody fusion platform that offers a surgical treatment proven to restore spinal balance, recreate spinal alignment and stability, and accelerate the return to normal activities.
Centinel Spine was the first company in the world to offer Integrated Interbody (a.k.a. Stand-Alone) fusion devices, and has a long clinical history in providing fusion solutions that conform to patient anatomy and capitalize on the body’s ability to heal itself.
Available devices include:
The 1st implantation of a STALIF device took place in 1988. Since the very first device was implanted until now, Centinel Spine has continued to innovate and improve upon its original STALIF design, with state-of-the-art solutions now existing in multiple material options and device sizes to best suit each patient’s unique needs.
The STALIF line of Integrated Interbody fusion implants are the longest implanted line of Integrated Interbody devices in the world.
30+ Year Clinical History with Worldwide Usage
Unparalleled clinical & biomechanical data, with average fusion rates of 92-95% 1,2,3
More than 75,000 device implantations and a reported reoperation rate of less than 1%
STALIF technology incorporates a proven design rationale based on AO principles of fracture fixation and Wolff’s Law of Bone Healing.
Wolff’s Law of Bone Healing states that bone grows where load is applied. That is why STALIF devices utilize specially designed screws that pull the spinal bones at the fusion site down to the device, in what is known as a "lag effect"—providing an active load to aid in the healing process.
Above: The Lag Effect is demonstrated.
STALIF devices are also designed to conform to patient anatomy. They come in a variety of sizes, heights, angles, and materials to fit each patient’s needs and offer the best chance of successful outcomes.
STALIF was developed with several specific patient care objectives in mind:
With a clinical heritage of more than 30 years, STALIF has been extensively studied.
After multiple published studies, the clinical & biomechanical data for STALIF strongly supports its safety and effectiveness. Here are just a few key takeaways from these numerous studies:

STALIF technology may not be suitable for all cervical fusion patients. In some situations, the use of a non-integrated interbody device may be needed. The ACTILIF C Portfolio of non-integrated interbody devices is proven to be a viable option.
ACTILIF C is a non-integrated anterior fusion device for the upper (cervical) spine (C2-T1) that is used in conjunction with a supplemental fixation option, such as a cervical plate, available in 2 material options (PEEK and FLX).
While the vast majority of insurance plans cover STALIF and ACTILIF, some fusion devices may be considered investigational by your insurance provider. Though reimbursement coverage for stand-alone fusions continues to increase, not all insurance companies cover these procedures. Centinel Spine offers a Patient Assistance Line (PAL) to qualified patients to help them to navigate insurance coverage for this surgery.
If you are not covered by your insurance provider, the PAL (Patient Assistance Line) is available to help you gain coverage for STALIF or ACTILIF procedures. The PAL is a reimbursement support service that assists YOU, the patient. Your PAL is dedicated to assisting YOU and working together with your surgeon, medical office, and insurance provider.

Problems can occur when you have spine surgery, including surgery with STALIF or ACTILIF implants. There is a risk that the surgery may not make you feel better or may cause you to feel worse. If this happens, you may need another surgery to help you feel better. View the specific problems that can occur during or after STALIF M, STALIF C, STALIF L, or ACTILIF C surgery.
Reimbursement is dynamic. Coding, coverage and payment are subject to change. Centinel Spine cannot guarantee reimbursement for any procedure associated with the use of its products. Providers should contact their specific payers if they have questions regarding coding, coverage or payment.

These individuals can inspire your journey to healing and life after disc replacement surgery—and the hope of freedom from spine-induced pain and discomfort.
With the total disc replacement, it’s like I’ve never had a neck problem!
I feel like my activity level is now a 10 out of 10! My recovery after prodisc was amazing.
Being a patient myself, I understand... the journey. [prodisc] allows my patients to return to their lives.
I probably feel better today than when I was 30 years old!
prodisc [gives] my patients the option to thrive and maintain the highest quality active lifestyle.
