Minimally Invasive Spine Surgery in Boston

What Is Minimally Invasive Spine Surgery?

Contemporary minimally invasive spine surgery uses advanced, muscle-sparing techniques to treat spinal conditions through small incisions. By avoiding extensive muscle dissection, these approaches can lead to less postoperative pain, faster recovery, and similar outcomes compared to traditional open spine surgery. At our practice, these procedures are performed by Dr. Bovonratwet, a fellowship-trained spine surgeon at Massachusetts General Hospital specializing in modern minimally invasive surgical techniques tailored to each patient.


This guide outlines common minimally invasive procedures including tubular laminectomy, tubular lumbar interbody fusion, lateral lumbar interbody fusion (XLIF), and anterior lumbar interbody fusion (ALIF).


Conditions Treated With Minimally Invasive Spine Surgery

Minimally invasive techniques may be used to treat:


My Approach to Minimally Invasive Spine Surgery

As a minimally invasive spine surgeon, my goal is simple: choose the least invasive treatment that safely and reliably relieves your symptoms.

Minimally invasive spine surgery is a powerful tool—but it is not the right solution for every patient. In my practice, I focus on matching the surgical technique to the underlying problem, rather than applying a one-size-fits-all approach.

For patients with conditions such as disc herniations or spinal stenosis, I often utilize muscle-sparing techniques, including tubular and endoscopic approaches. These allow for effective nerve decompression while preserving the paraspinal muscles and normal spinal structures.

When spinal instability is present, a fusion procedure may be necessary. In these cases, I frequently perform minimally invasive fusion techniques designed to achieve the same goals as traditional open surgery—restoring stability and relieving pain while minimizing tissue disruption.

There are also situations where a traditional open approach may be the safer and more effective option, including complex deformity, significant instability, or revision surgery. The priority is always achieving the best long-term outcome—not simply using the smallest incision.

In every case, I take time to walk patients through:

  • Whether surgery is truly necessary

  • All appropriate non-surgical options

  • The risks and benefits of each approach

  • What recovery realistically looks like

Ultimately, successful spine surgery is defined by how well the operation addresses the root cause of your symptoms—not by incision size alone.

Minimally Invasive Surgical Techniques

A range of advanced modern minimally invasive procedures are available, depending on your diagnosis:

  • A tubular laminectomy is a minimally invasive procedure used to relieve pressure on spinal nerves caused by conditions such as spinal stenosis or disc herniation.

    How it is performed:

    • A small incision (typically 18 mm or size of a nickel) is made in the back.

    • A series of tubular dilators gently separate muscle fibers rather than cutting them.

    • A working tube (retractor) is placed to maintain a small corridor to the spine.

    • The surgeon removes a portion of bone and ligament (lamina and ligamentum flavum) to create more space for the nerves.

    Key benefits:

    • Preserves the spinous process

    • Preserves surrounding muscles and soft tissue

    • Less postoperative pain compared to open surgery

    • Faster return to activity

  • A tubular TLIF is a minimally invasive fusion procedure used to stabilize the spine in conditions such as spondylolisthesis or recurrent disc herniation.

    How it is performed:

    • A small posterior incision is made.

    • A tubular retractor is used to access the spine through muscle-splitting techniques.

    • The damaged disc is removed from between the vertebrae.

    • Bone graft and interbody cage is placed in the disc space to restore height and promote fusion.

    • Pedicle screws and rods are inserted percutaneously to provide stability while fusion occurs.

    Key benefits:

    • Minimal disruption of paraspinal muscles

    • Restoration of disc height and alignment

    • Fusion success rates comparable to open techniques

  • XLIF is a minimally invasive fusion approach that accesses the spine from the patient’s side (lateral approach), avoiding disruption of the back muscles.

    How it is performed:

    • A small incision is made on the side of the abdomen.

    • The surgeon accesses the spine by gently moving through the psoas muscle under neuromonitoring guidance.

    • The damaged disc is removed and replaced with an interbody cage filled with bone graft.

    • In some cases, supplemental posterior instrumentation may be added.

    Key benefits:

    • Avoids major back muscle dissection

    • Large implant placement for indirect decompression of nerves

    • Reduced blood loss and postoperative pain

  • ALIF is a minimally invasive fusion procedure performed through the front of the abdomen, allowing direct access to the lumbar disc space without disturbing the spinal muscles.

    How it is performed:

    • A small incision is made in the lower abdomen.

    • The spine is accessed by gently moving abdominal structures and blood vessels aside (often with a vascular surgeon assisting).

    • The disc is removed and replaced with a large interbody cage filled with bone graft.

    • Supplemental posterior fixation may be used depending on the case.

    Key benefits:

    • Direct access to the disc space

    • Ability to restore lumbar lordosis (spinal alignment)

    • No disruption of posterior spinal muscles

Frequently Asked Questions

Find answers to common questions about minimally invasive spine surgery, including candidacy, recovery, risks, and how it compares to traditional open surgery.

  • Minimally invasive spine surgery can offer advantages such as smaller incisions, less muscle disruption, and faster recovery. However, it is not inherently better in every situation. When used in appropriate patients, outcomes are similar to traditional open surgery. The best approach depends on your specific condition, anatomy, and surgical goals.

  • Many patients with conditions such as disc herniation, spinal stenosis, or certain types of spinal instability may be candidates for minimally invasive techniques. Ideal candidates typically have localized pathology that can be addressed without extensive exposure.

    A detailed evaluation, including imaging and physical examination, is necessary to determine whether a minimally invasive approach is appropriate.

  • Minimally invasive techniques may not be suitable for patients with:

    • Complex spinal deformity

    • Significant or multi-level instability

    • Extensive prior spine surgery

    • Conditions requiring wide decompression or reconstruction

    In these situations, a traditional open approach may provide a safer and more effective long-term outcome.

  • Recovery varies depending on the procedure performed, but in general:

    • Many patients go home the same day or within 24 hours

    • Walking is encouraged shortly after surgery

    • Light activities may resume within a few weeks

    • Full recovery typically takes several weeks to a few months

    Your recovery timeline will depend on the specific procedure and your overall health.

  • Minimally invasive spine surgery is safe and effective when performed in appropriate patients. Potential benefits include reduced blood loss, lower infection risk, and faster recovery.

    However, safety depends on proper patient selection and surgical expertise, not just the size of the incision. In some cases, a traditional open approach may be safer.

  • Not all patients require a spinal fusion. Many conditions, such as disc herniations or certain cases of spinal stenosis, can be treated with decompression alone.

    Fusion is typically recommended when there is spinal instability, deformity, or significant degeneration that requires stabilization.

  • As with any surgery, there are risks, including:

    • Infection

    • Bleeding

    • Nerve injury

    • Persistent or recurrent symptoms

    • Need for additional surgery

    These risks are generally low, and your surgeon will review them in detail based on your specific condition.

  • The most important step is an accurate diagnosis and a thoughtful discussion of your options. The choice between minimally invasive and traditional open surgery depends on:

    • Your specific diagnosis

    • The severity and location of the problem

    • Your overall health and goals

    A personalized evaluation with Dr. Bovonratwet will help determine the safest and most effective treatment plan.
