Who Qualifies for Motion-Preserving Spine Surgery?

People with degenerative disc disease, herniated discs, or cervical spine problems may qualify for motion-preserving spine surgery when conservative care no longer relieves pain. Doctors also consider spinal stability, healthy facet joints, and preserved bone strength while determining surgical eligibility.

Performing motion-preserving surgery without confirming proper candidacy can increase the risk of poor outcomes, persistent symptoms, and spinal instability. Therefore, our spine surgeon, Dr. Vadim Lerman at Total Orthopedics & Sports Medicine, carefully assesses your candidacy before recommending surgery. He reviews your symptoms, physical exam findings, and imaging results to determine which motion-preserving procedure may suit your condition. Call 855-321-6784 to book your appointment.

Who Is a Good Candidate for Motion-Preserving Surgery?

A good candidate for motion-preserving surgery usually has healthy bone quality, stable spinal alignment, preserved facet joints, and symptoms linked to a specific spinal level. Our surgeon, Dr. Vadim Lerman, also considers activity level, neurological findings, and previous nonsurgical treatment before deciding if preserving spinal motion is a safe and suitable option.

Here is how these factors can affect your candidacy for motion-preserving surgery:

1. Bone Quality

Good bone strength helps the artificial disc stay firmly supported between the vertebrae. If your bones are too weak, the implant may shift or sink over time. For example, a 2025 Global Spine Journal study compared 38 patients with osteopenia with 38 patients with normal bone density. Implant subsidence occurred in 15.2% of patients with osteopenia, compared with 2.7% in those with normal bone density.

2. Spinal Alignment

Your spine should remain properly aligned and stable before minimally invasive surgery. Significant slippage or abnormal movement can place extra stress on a motion-preserving device. In these cases, our surgeon may recommend a procedure that provides more stability, such as traditional spinal fusion.

3. Facet Joint Health

Healthy facet joints help maintain normal movement after motion-preserving surgeries like artificial disc replacement. On the other hand, severe facet joint degeneration can limit motion and continue causing pain even after the damaged disc is replaced. A Neurosurgery study of 161 patients with cervical disc replacement found that greater facet arthropathy was associated with reduced segmental range of motion after surgery.

4. Affected Spinal Level

The number of spinal levels that need treatment can directly affect your candidacy for motion-preserving surgery. These procedures are usually more suitable when degeneration is limited to one or two levels. If multiple disc levels are severely damaged, preserving normal motion becomes more difficult, and you may not qualify for the surgery.

5. Activity Level

Your activity level helps our surgeon judge how much stress the treated spinal segment will face after surgery. If you regularly perform heavy lifting, participate in high-impact sports, or do strenuous work, certain motion-preserving procedures may not be suitable.

6. Neurological Findings

Mild-to-moderate nerve compression that matches your imaging findings may support candidacy for motion preservation. In contrast, severe spinal cord damage, major weakness, or advanced neurological problems may lead our surgeon to recommend a different surgical approach.

7. Previous Nonsurgical Treatment

Your response to nonsurgical treatment also affects surgical eligibility. Dr. Vadim Lerman usually considers motion-preserving surgery after rehabilitation, medications, injections, or activity changes fail to provide lasting relief. If these treatments still control your symptoms, he may recommend continuing conservative care instead of surgery.

Does Age Affect Motion-Preserving Surgery Candidacy?

Yes, age can affect candidacy, but there is no single ideal age for motion-preserving surgery. Younger, active adults may qualify more easily because they often have stronger bones and less advanced joint degeneration. Still, older adults can also qualify if they have good bone quality, healthy facet joints, and a stable spine.

In fact, a 2025 study in the North American Spine Society Journal compared 132 patients under 65 with 56 patients aged 65 or older. Researchers found no significant difference in complication or reoperation rates between the two groups after cervical disc arthroplasty.

Do Cervical and Lumbar Candidacy Criteria Differ?

Yes, cervical and lumbar motion preservation surgery have different candidacy criteria. For cervical replacement, surgeons usually look for nerve or spinal cord compression that matches your symptoms and imaging. They also consider symptoms such as arm pain, numbness, or weakness. For lumbar replacement, surgeons confirm disc-related lower back pain, healthy facet joints, and a stable lumbar spine.

What Spine Conditions May Qualify for Motion Preservation?

Motion preservation can treat spinal conditions like degenerative disc disease, herniated discs, cervical radiculopathy, and selected cases of spinal stenosis. Some patients with disc-related neck or back pain may also qualify for surgery.

Which Tests Determine If You Qualify for Surgery? 

Our surgeon, Dr. Vadim Lerman, usually uses X-rays, MRI scans, CT scans, and bone density testing to determine if you qualify for motion-preserving spine surgery. He also performs physical exams to assess your strength, reflexes, sensation, gait, and spinal mobility.

Here is what each test can reveal:

1. X-Rays

X-rays show spinal alignment, disc height, bone changes, and movement between the vertebrae. Flexion-extension X-rays can also reveal spinal instability. If the treated segment moves abnormally, our surgeon may advise against a motion-preserving procedure because it may not provide sufficient stability.

2. MRI Scan

An MRI shows the spinal discs, nerve roots, spinal cord, and surrounding soft tissues in detail. It can identify herniated discs, spinal stenosis, and nerve compression. These findings help confirm whether the damaged disc matches your symptoms and may benefit from motion-preservation spine surgery.

3. CT Scan

A CT scan shows the bones of your spine in greater detail than a standard X-ray. It helps identify facet joint damage, bone spurs, and other structural changes. Your surgeon uses these findings to assess whether the affected spinal segment has enough support for a motion-preserving device.

4. Bone Density Test

Bone density testing measures the strength of your bones and checks for osteoporosis or significant bone loss. Adequate bone strength helps support an artificial disc and lowers the risk of implant subsidence. On the other hand, poor bone quality may make traditional fusion procedures a safer option.

5. Physical Exam

During the physical exam, your surgeon may use specific tests such as the Spurling test, straight-leg raise, Hoffmann sign, and heel-to-toe walking test. These assessments help identify cervical or lumbar nerve involvement, spinal cord compression, and balance problems. The results also help confirm whether your symptoms match the spinal level shown on imaging.

When Is Spinal Fusion a Better Option?

Spinal fusion may be a better option when your spine needs permanent stability rather than preserved motion. Surgeons may recommend it for severe spinal instability, advanced facet joint damage, significant deformity, poor bone quality, or vertebral slippage. In these cases, motion-preserving surgery may not provide enough support or reliable long-term stability.

Spinal fusion can also be more suitable when disc degeneration affects several spinal levels or the damaged segment cannot safely support an artificial disc. The procedure joins two or more vertebrae and limits movement at that level. As a result, it can stabilize the spine, relieve pressure on nerve roots, and reduce pain caused by abnormal spinal motion.

What Should You Ask a Spine Surgeon Before Surgery?

Before motion-preserving spine surgery, ask your surgeon about your diagnosis, recommended procedure, expected recovery, risks, and alternative treatments. You should also understand why the surgeon prefers motion preservation over spinal fusion for your condition. Clear answers can help you understand the treatment plan and make a more informed decision.

Here are some other questions you should ask:

• How many levels of my spine need treatment?
• What results can I realistically expect after surgery?
• Could I need additional surgery in the future?
• What complications should I watch for during recovery?
• Will I need a brace after the procedure?
• How soon can I travel after surgery?
• Are there activities I should permanently avoid?
• What factors could slow down my recovery?
• How long will the surgery usually take?
• How should I care for the incision at home?

What Are the Benefits of Motion Preservation Surgery?

Motion-preservation surgery can relieve nerve- or disc-related symptoms while maintaining movement at the treated spinal level. Unlike spinal fusion, it avoids permanently joining the vertebrae. This can result in better spinal mobility, less stress on nearby spinal segments, and greater flexibility during everyday movement.

Here are some other benefits of motion-preserving spine surgery:

• Eliminates the risk of nonunion: Since the vertebrae are not fused, patients do not develop pseudarthrosis, in which the bones fail to fuse properly.
• May reduce long-term stiffness: Preserving movement at the treated level can help avoid the permanent loss of motion that comes with fusion.
• Can allow earlier rehabilitation: Patients may begin neck or back movement sooner because recovery does not depend on waiting months for a solid fusion to form.

In fact, a 2025 meta-analysis published in the Journal of Orthopaedic Surgery and Research found that cervical disc replacement preserved more motion than fusion. Furthermore, among 2,533 patients, those who received disc replacement had a significantly lower rate of repeat surgery. The study also found less adjacent segment degeneration in patients treated with disc replacement.

Should You Get a Second Opinion Before Surgery?

Yes, you may consider a second opinion before undergoing motion-preserving spine surgery if you are uncertain about your diagnosis or recommended treatment. Another spine specialist can independently assess your condition and determine if surgery is appropriate. They may also suggest another option, such as spinal fusion surgery or continued conservative treatment.

In addition, a second opinion can help you compare the expected benefits, risks, recovery time, and long-term effects of each available procedure. However, if you have progressive weakness or serious spinal cord compression, you should avoid delaying urgent treatment.

How Do You Prepare Once You Are Approved for Surgery?

Once your surgeon approves you for motion-preserving spine surgery, complete the required medical tests, avoid smoking and alcohol, and follow all activity restrictions. You should also arrange transportation and prepare your home to make recovery easier after surgery.

Here are some other steps you must take before surgery:

• Inform your doctor about medications: Share all prescription medicines, supplements, and over-the-counter drugs you currently take.
• Follow medication instructions: Your surgeon may ask you to stop or adjust certain medications before the procedure.
• Report any new illness: Tell your surgical team if you develop a fever, an infection, a cough, or any other health problem.
• Follow hygiene instructions: Shower as directed and avoid applying lotions, creams, or perfumes before arriving for surgery.
• Wear comfortable clothing: Choose loose clothes that are easy to put on after the procedure.
• Bring required documents: Carry your identification, insurance information, medication list, and any requested medical records.

For more details on how to prepare, review our pre-operative instructions guide before your procedure. It covers medication guidance, pre-surgery preparation, and recovery planning.

What Happens on the Day of Spine Surgery?

On the day of motion-preserving spine surgery, our surgical team conducts a preoperative assessment, confirms the treatment plan, and administers anesthesia. Dr. Vadim Lerman then performs the planned motion-preserving procedure and protects the surrounding nerve roots and spinal cord. Afterward, the team monitors you closely as you wake from anesthesia.

Here’s what you can expect at each stage of the procedure:

1. Preoperative Preparation

After you arrive, our care team checks your vital signs, medication history, allergies, and fasting status. You then change into a surgical gown and receive an IV for fluids and medications. Next, our surgeon confirms the correct spinal level and reviews the procedure with you.

2. Anesthesia Administration

An anesthesiologist gives you general anesthesia so you remain asleep and comfortable throughout the surgical procedure. The anesthesia team continuously tracks your heart rate, blood pressure, breathing, and oxygen levels.

3. Performing the Surgery

After the anesthesia takes effect, Dr. Vadim Lerman begins the surgical procedure. The exact approach depends on your spinal condition and the motion-preserving technique selected. The surgery generally involves the following steps:

1. Our surgeon makes a small incision to access the cervical or lumbar spine.
2. Next, he carefully moves the surrounding tissues aside while protecting the nearby nerves and blood vessels.
3. He removes damaged disc tissue or other structures that are pressing on the nerve roots or spinal canal.
4. If needed, he creates additional space to relieve pressure on the affected nerves.
5. Our surgeon then prepares the treated spinal segment and places the artificial disc or other motion-preserving device in the correct position.
6. Once the device position and treated area are confirmed, he closes the incision with sutures or surgical adhesive.
7. He then applies a sterile dressing to protect the surgical site.

4. Recovery After Anesthesia

After surgery, our team moves you to a recovery area while the anesthesia wears off. Nurses monitor your vital signs and watch for nausea, dizziness, or other immediate concerns. We also make sure you can safely begin drinking, eating, or walking when appropriate.

5. Discharge or Hospital Observation

Our surgeon decides if you can return home the same day or if you need overnight observation. In fact, most cervical disc replacement procedures are done on an outpatient basis. Before discharge, we also explain medication use, incision care, activity restrictions, warning signs, and your follow-up schedule.

When Can You Return to Work, Driving, or Sports?

Recovery after motion-preserving spine surgery usually takes about 6 weeks to 6 months. The exact timeline depends on the procedure, the treated spinal level, your overall health, and the extent of nerve involvement. For example, recovery after cervical disc replacement may be faster compared to lumbar disc replacement.

However, every patient progresses differently, so our surgeon adjusts activity based on healing. Here is a general recovery timeline after motion-preserving spine surgery:

Duration	Recovery expectations
First few days	Short walks, pain control, and basic daily activities
1–2 weeks	Incision healing and gradual return to light activities
2–4 weeks	Driving may resume once you stop taking pain medication
4–6 weeks	Increased spinal mobility and gradual return to routine activities
6–12 weeks	Physical therapy, strengthening, and a gradual return to strenuous activities
3–6 months	Heavy lifting and sports may resume after the surgeon’s clearance
Up to 6 months	Most patients continue improving toward full recovery and normal activity

How Dr. Vadim Lerman Monitors Your Spine After Surgery?

Dr. Vadim Lerman monitors your spine through scheduled follow-up visits after motion-preserving spine surgery. During these visits, he tracks symptom improvement, nerve recovery, spinal motion, and healing progress. He may also review follow-up imaging to confirm that the treated spinal segment maintains proper alignment and normal motion.

As recovery continues, Dr. Lerman compares your progress from one visit to the next. He looks for changes in pain, numbness, weakness, mobility, and daily function. This ongoing monitoring helps him identify possible complications early and adjust your recovery plan or recommend revision surgery if needed.
