How Is Minimally Invasive Spine Surgery Different?

Minimally invasive spine surgery treats the affected part of your spine through smaller surgical incisions. This allows the surgeon to limit damage to nearby muscles and healthy tissue. Compared with open surgery, you may experience less postoperative pain, reduced blood loss, and a faster recovery.

At Total Orthopedics & Sports Medicine, our spine surgeon, Dr. Dante Leven, evaluates your symptoms, imaging, and spinal condition to determine your candidacy for a minimally invasive approach. He then selects a surgical technique that provides adequate access to the affected area while preserving healthy structures. Call us at 855-321-6784 to schedule your appointment with Dr. Dante Leven.

How Does Minimally Invasive Spine Surgery Compare With Open Surgery?

Minimally invasive spine surgery (MISS) focuses on treating a specific area of your spine with less disruption to nearby tissue. In contrast, open surgery gives the surgeon wider access to the spine when more extensive correction is needed. Your surgeon evaluates the location and extent of the problem before choosing the most appropriate approach.

Beyond surgical access, minimally invasive spine surgery vs open surgery also differ in several aspects of treatment and recovery, such as:

Minimally Invasive Spine Surgery	Open Surgery
Often involves a shorter hospital stay	May require a longer hospital stay
May allow earlier walking	Mobility may take more time
Often involves fewer recovery restrictions	May involve more recovery restrictions
May reduce the need for pain medication	Pain medication may be needed longer
Often causes less blood loss	May involve greater blood loss
Some procedures are outpatient	Complex procedures may require hospitalization

In addition, minimally invasive procedures use real-time imaging and specialized spinal instrumentation. On the other hand, traditional surgery may require more extensive preoperative preparation and a longer operative time. As a result, you may spend more time under general anesthesia, particularly during complex procedures. Besides that, MISS usually results in smaller scars than traditional open spine surgery.

How Are Muscles Protected During Minimally Invasive Surgery?

During minimally invasive surgery, your surgeon protects the back muscles by gently separating the muscle fibers instead of cutting through them. Small tubes or retractors create a narrow path to the spine. This approach limits soft tissue damage and helps preserve the muscles that support and stabilize your spine.

Surgeons use the following techniques and specialized tools to protect the muscles while creating a safe path to the spine:

• Muscle-splitting corridors: Instruments pass through natural spaces between muscle fibers.
• Sequential dilation: Small tubes gradually create a treatment path without cutting through the muscle.
• Tubular retractors: Hollow tubes gently hold the muscles aside during surgery.
• Advanced imaging: Cameras and imaging systems help guide instruments accurately through a limited space.

A study of 59 patients found that the multifidus muscle decreased in size by only 12.2% after minimally invasive surgery. In comparison, it decreased by 36.8% after open surgery. Patients in the MIS group also had less postoperative back pain and disability.

What are the Types of Minimally Invasive Spine Surgery?

The main types of minimally invasive spine surgery include discectomy, spinal decompression, laminectomy, and foraminotomy. Other commonly performed procedures include spinal fusion, artificial disc replacement, and vertebral augmentation. Your surgeon chooses the procedure based on the affected area, your diagnosis, and the treatment needed.

Here is how each surgical procedure addresses the problem while minimizing unnecessary disruption to nearby tissues:

1. Discectomy

A minimally invasive discectomy removes the portion of a herniated disc that presses on a nerve root. Your surgeon reaches the disc through a narrow working channel and removes only the material causing pain. This helps relieve pain and pressure on the nerve while preserving healthy disc tissue whenever possible.

2. Spinal Decompression

Spinal decompression creates additional space around compressed spinal nerves. Your surgeon may remove a small amount of bone, ligament, or other tissue that narrows the spinal canal. The goal is to relieve nerve pressure while preserving the structures that support your spine. This approach can help preserve spinal stability.

3. Laminectomy

A minimally invasive laminectomy removes a targeted portion of the lamina, which forms the back of a vertebra. This can create more space when spinal stenosis compresses nearby nerves. Instead of exposing a broad section of the spine, the surgeon reaches the affected area through a narrow surgical pathway. This helps preserve more surrounding muscle and bone.

4. Foraminotomy

A foraminotomy enlarges the intervertebral foramen, the opening where a spinal nerve exits the spine. Bone spurs, disc material, or thickened tissue can make this opening too narrow. Your surgeon removes the tissue responsible for the narrowing while preserving nearby structures whenever possible.

5. Spinal Fusion

Minimally invasive spinal fusion stabilizes painful or unstable vertebrae through smaller surgical pathways. Your surgeon may place pedicle screws and rods using imaging guidance rather than exposing a long section of the spine. Bone grafts are then placed between the affected vertebrae to promote fusion. Over time, the bones grow together and create a more stable section of the spine.

6. Artificial Disc Replacement

Artificial disc replacement removes a damaged spinal disc and replaces it with a device designed to maintain movement between the vertebrae. Unlike fusion, the procedure does not intentionally join the treated bones together. Surgeons commonly use this approach for selected patients with disc problems in the cervical spine. However, not every patient is a suitable candidate for this approach.

7. Vertebral Augmentation

Minimally invasive compression vertebral augmentation, such as kyphoplasty, treats certain collapsed vertebrae through small access points. Your surgeon guides a narrow instrument into the fractured vertebra using imaging. Bone cement then stabilizes the weakened bone. In selected patients, this can reduce fracture-related pain without requiring a larger surgical exposure.

Is Endoscopic Spine Surgery the Same as MIS?

No, endoscopic surgery is not the same as minimally invasive spine surgery (MIS). Instead, it is one type of MIS that uses a small camera and specialized instruments to reach the treatment area. Other minimally invasive procedures may use tubular retractors, microscopes, or imaging guidance without an endoscope.

During endoscopic back surgery, your surgeon inserts a thin tube with a small camera through an incision typically less than 1 cm. The camera sends a magnified view of the treatment area to a monitor in endoscopic procedures. Using this view, the surgeon guides specialized instruments through the same narrow channel and treats the problem without widely exposing the spine.

What Are the Benefits of Minimally Invasive Surgery?

Less tissue damage, reduced blood loss, and less pain are key benefits of minimally invasive surgery. This targeted approach may also help maintain the natural support around your spine during recovery. Here are some other benefits of minimally invasive surgery:

• Less muscle disruption: Preserving more muscle may help maintain strength around your spine.
• Preservation of spinal support: Less removal of healthy bone and supporting tissue may help preserve natural stability.
• Reduced risk of wound problems: A smaller incision site may reduce certain wound-healing complications.
• Less need for tissue retraction: Surgeons can reach the target area without holding large amounts of muscle aside.
• More targeted treatment: Specialized instruments allow your surgeon to address the affected structure while preserving healthy tissue nearby.

For degenerative lumbar conditions, a meta-analysis of 53 studies found that minimally invasive spine surgery was associated with lower blood loss, shorter hospital stays, and fewer complications than open surgery. A systematic review of 26 lumbar fusion studies also found less blood loss and earlier walking after minimally invasive lumbar spine fusion. Another review of 22,475 patients reported a 1.5% surgical-site infection rate with minimally invasive surgery, compared with 3.8% with open surgery.

Which Surgical Approach Has Fewer Complications?

Minimally invasive spine surgery may have fewer complications than traditional open surgery for appropriately selected patients. Its smaller surgical pathway may reduce certain risks linked to greater tissue exposure and muscle disruption. Still, complications such as infection can occur. Your individual risk also depends on the procedure, your spinal condition, overall health, and your surgeon’s experience.

Our minimally invasive spine surgeon, Dr. Dante Leven, uses image-guided navigation and minimally invasive techniques to improve accuracy during back surgery. He carefully plans the surgical pathway and limits unnecessary disruption to healthy tissue. When needed, he also uses neuromonitoring to track nerve function during the procedure. These measures help reduce avoidable surgical risks. Schedule an appointment with Dr. Dante Leven to discuss the safest surgical approach for your spine condition.

Which Conditions Can Less-Invasive Spine Surgery Treat?

Less-invasive spine surgery can treat herniated discs, spinal stenosis, degenerative disc disease, and certain spinal fractures. It may also treat some cases of spinal instability or nerve compression. But your surgical eligibility depends on the location and severity of the problem, as well as the type of correction you need.

In addition, a minimally invasive approach may not provide enough access for every spinal problem. Your surgeon may consider another surgical approach in the following conditions:

• Severe spinal deformity: Major alignment issues may require a more significant correction.
• Significant spinal instability: Several unstable levels may need more extensive stabilization.
• Extensive spinal damage: Widespread damage may require treatment across multiple structures.
• Complex spinal tumors: Some spinal tumors require broader access for safe removal.
• Major trauma: Severe fractures or injuries involving several spinal vertebrae may need more extensive reconstruction.

Is Minimally Invasive Spine Surgery Right for Me?

You may be a good candidate for minimally invasive spine surgery if your condition can be treated without a more extensive surgical approach. Your surgeon checks whether your symptoms match the problem shown on imaging. Your overall health, spinal stability, and response to nonsurgical treatments also help determine whether this approach is appropriate for you.

Here are some additional factors that may support your candidacy for a minimally invasive procedure:

• Localized Spine Problem: Symptoms involve only one or a few spinal levels.
• Good Bone Quality: Bone is strong enough to support the procedure when stabilization is needed.
• Healthy Alignment: The spine does not require major deformity correction.
• Limited Damage: Structural damage does not affect a broad area of the spine.
• Surgical Fitness: Overall health allows the procedure to be performed safely.

How Do Doctors Choose the Right Spine Procedure?

Our surgeon, Dr. Dante Leven, chooses the right spine procedure by matching your symptoms with findings from your examination and imaging studies. He identifies the exact structure causing the problem and checks your spinal stability and alignment. Then, he determines which surgical treatment can address the problem while preserving healthy tissue whenever possible.

Additionally, our spine specialist evaluates the spinal column, facet joints, and intervertebral discs to determine which structures remain stable and which require treatment. He also checks the relationship between adjacent vertebrae. These findings help determine whether decompression alone is enough or stabilization is also needed. This detailed evaluation helps him avoid treating areas of your spine that are not contributing to your symptoms.

Common Questions Patients Ask Before Surgery

Patients often come to us with multiple questions about surgery. They want to know whether they really need surgery, what it will change, and whether other options are available. They also want to know how surgery could affect their daily activities or what may happen if they wait. Some patients have concerns about possible complications and the recovery process.

Dr. Dante Leven addresses these concerns by connecting each recommendation to your condition and treatment goals. He explains what the procedure is meant to correct, why he recommends it, and what other options you may have. He also discusses the benefits and potential risks, helping you make a clear, informed decision. If you’re unsure about moving forward with surgery, book an appointment to review your options with Dr. Dante Leven.

Can Multiple Spine Levels Be Treated at Once?

Yes, two or more vertebrae can sometimes be treated during the same minimally invasive spine procedure. Your surgeon evaluates each affected level to determine whether treating them together is safe and necessary. The decision depends on your diagnosis, spinal stability, and the number of levels contributing to your symptoms.

Furthermore, not every affected level requires the same treatment. One level may need spinal decompression to relieve pressure on a compressed nerve, while another may require stabilization because of abnormal movement. Your surgeon evaluates each level separately and combines procedures only when necessary. This allows the treatment to address the specific problem at each level.

When Do Surgeons Recommend Open Spine Surgery?

Surgeons recommend open spine surgery when the required correction cannot be safely completed through a limited surgical pathway. For example, it may be necessary for major deformity correction, unstable fractures, large spinal tumors, or complex revision surgery. Open surgery also gives your surgeon enough space to place implants and repair multiple damaged parts of the spine during the same procedure.

Here are some other situations when open spine surgery may be recommended:

• Progressive muscle weakness: Worsening weakness can indicate increasing nerve damage.
• Loss of bowel or bladder control: This may signal severe compression of the lower spinal nerves.
• Cauda equina syndrome: Rapid decompression may be needed to protect nerve function.
• Severe spinal cord compression: Continued pressure can damage the spinal cord and affect its function.
• Spinal infection with nerve compression: Surgery may be required to remove infected tissue and relieve pressure on nearby nerves.

How Long Does Minimally Invasive Spine Surgery Take?

Minimally invasive spine surgery typically takes about one to three hours, although the exact time varies by procedure. A simple discectomy may take around an hour, while fusion can take several hours. The number of spinal levels treated and the complexity of your condition can also affect the surgical time.

A study comparing minimally invasive and open microdiscectomy reported an average surgical time of 76.8 minutes for the minimally invasive approach. This supports the roughly one-hour timeframe for simpler procedures. On the other hand, fusion procedures often take longer. A study of single-level minimally invasive TLIF reported an average operative time of 161 minutes (2.7 hours).

Will You Need to Stay in the Hospital After Surgery?

No, you may not need to stay in the hospital after minimally invasive spine surgery. Some procedures are performed as an outpatient procedure, allowing you to return home the same day. But a more complex surgery may require an overnight stay so your medical team can monitor your pain, movement, and overall recovery.

Your discharge time also depends on how well you recover during the first few hours after surgery. Your medical team checks whether you can walk safely, control your chronic pain with medication, eat or drink, and urinate normally. If these recovery goals take longer to meet, you may need to stay in the hospital for additional monitoring.

How Long Is the Recovery From Spine Surgery?

Recovery from spine surgery typically takes about 6 to 12 weeks, although the minimally invasive spine surgery recovery time varies by procedure. You may return to light activities sooner after a minimally invasive procedure. However, full recovery after spinal fusion surgery can take several months as the bones continue to heal.

A study of 230 patients undergoing minimally invasive spine surgery found that they returned to work a median of 14 days after minimally invasive laminectomy. After minimally invasive TLIF, the median return-to-work time was 25 days. Moreover, patients returned to driving within about 11 and 18.5 days, respectively. Another study comparing MIS-TLIF with open TLIF reports that MIS-TLIF patients returned to work in a median of 8.5 weeks, compared with 17.1 weeks after open surgery.

At our clinic, we commonly see patients who feel better after surgery but are unsure how much activity their spine can safely handle. Our spine specialist, Dr. Dante Leven, evaluates your strength, movement, and functional progress alongside your surgical healing. He then assesses for movement or strength limitations and uses those findings to guide your return to exercise and sports. If you are unsure about returning to exercise or sports, schedule an appointment with Dr. Dante Leven.

How Much Pain Should You Expect After Surgery?

Some postoperative pain is expected during the first few days, although its intensity varies. Most discomfort results from the incision and surrounding muscles and should gradually improve. Your medical team may recommend medication, ice, and early movement to keep the pain manageable as you recover.

However, some types of pain can signal a complication and need prompt medical attention. Contact your medical team if you experience:

• Pain that suddenly increases after it had started to improve.
• New or worsening shooting pain in your arms or legs.
• Pain occurs with new weakness or difficulty moving a limb.
• Pain is accompanied by new bowel or bladder problems.
• Increasing incision pain occurs along with fever, redness, swelling, or drainage.
