ZIP Minimally Invasive Lumbar Fusion

A less invasive alternative to traditional lumbar fusion surgery. Using a screwless interspinous fixation system, Dr. Shamloo can stabilize the affected portion of the lumbar spine through a very small incision — outpatient, under sedation, home the same day.

Why choose a minimally invasive approach?

The word “fusion” can make patients picture a major spine surgery with large incisions, extensive hardware, and a long recovery. For appropriately selected patients, that may not be the only option.

Dr. Shamloo’s approach is designed to provide spinal stabilization and fusion through a much smaller surgical pathway, minimizing disruption to the surrounding muscles and tissues:

Very small incision
Targeted access to the affected spinal level
Outpatient procedure
Sedation rather than general anesthesia for appropriate patients
Return home the same day
Most normal daily activities can resume the next day
Temporary bending and lifting restrictions for one to two weeks

A traditional approach may instead involve more extensive exposure, larger incisions, general anesthesia, a hospital stay, longer initial recovery, and more significant postoperative restrictions.

What is minimally invasive lumbar fusion?

The procedure is designed to stabilize a painful or unstable spinal segment and allow the bones to fuse, while using a substantially less disruptive surgical approach. Rather than requiring a large surgical exposure, it uses a small incision and specialized instrumentation to access and stabilize the affected level.

Dr. Shamloo primarily uses a screwless interspinous fixation system for appropriately selected patients. The technology currently used in his practice includes the Aurora Spine ZIP platform, developed as a minimally invasive alternative to traditional pedicle-screw fixation.

The specific implant system used may evolve as newer technologies become available.

Who may be a candidate?

The approach is best suited to carefully selected patients whose diagnosis, spinal anatomy, source of pain, and overall health are appropriate for this type of stabilization. Potential candidates may include patients with conditions such as:

Degenerative disc disease
Lumbar spinal stenosis
Spondylolisthesis
Spinal instability
Certain degenerative conditions of the lumbar spine
Certain traumatic conditions
Persistent pain associated with a specific unstable spinal segment

The most important question is whether the affected spinal level is actually responsible for your symptoms and whether stabilization is reasonably expected to provide meaningful benefit. Dr. Shamloo evaluates each patient’s imaging, symptoms, examination, medical history, and treatment history first.

A same-day, minimally invasive procedure

One of the most important differences between this approach and traditional lumbar fusion is how much surgery the patient actually experiences. For appropriately selected patients, the procedure is performed through a very small incision, under sedation, as an outpatient.

Patients recover under observation following the procedure and return home the same day. There is generally no need for a prolonged hospital stay.

What is recovery like?

The minimally invasive approach is designed to allow patients to return to normal life quickly. Most patients can resume most normal daily activities the following day.

For approximately the first one to two weeks, patients generally have temporary restrictions on bending, heavy lifting, and strenuous activity. These restrictions help protect the treatment area during the initial healing period.

While patients may be able to return to many everyday activities very quickly, spinal fusion itself is a biological process that continues to develop over time. Your specific restrictions and follow-up schedule depend on your individual condition and recovery.

Potential benefits

For appropriately selected patients, minimally invasive lumbar fusion may offer several potential advantages compared with more extensive traditional fusion surgery:

Smaller incision
Less disruption to surrounding tissues
Reduced surgical exposure
Outpatient treatment
No general anesthesia for appropriate patients
Same-day discharge
Faster return to normal daily activities
Shorter initial recovery period
Stabilization of the affected spinal segment

Minimally invasive does not mean that the procedure is minor. Fusion is still a significant medical procedure intended to create lasting stabilization of the spine — the difference is that it is designed to accomplish that goal through a less disruptive approach.

How the procedure works — a targeted posterior approach through a small incision.

STEP 01

Identify the level

After identifying the spinal level responsible for your symptoms, Dr. Shamloo uses a targeted posterior approach to access the affected area.

STEP 02

Place the implant

Through a small incision, specialized instruments position the stabilization implant between the appropriate spinal structures — without traditional pedicle-screw fixation.

STEP 03

Stabilize the segment

The implant stabilizes the affected segment and supports the body’s natural fusion process, while minimizing disruption to the surrounding anatomy.

STEP 04

Home the same day

Patients recover under observation and return home the same day, with temporary bending and lifting restrictions for approximately one to two weeks.

CANDIDACY

Who this is for

This approach is not appropriate for every patient who has been told they need fusion. It is best suited to carefully selected patients whose diagnosis, spinal anatomy, source of pain, and overall health are appropriate for this type of stabilization. The most important question is not simply whether a patient has a condition that can be treated with fusion — it is whether the affected spinal level is actually responsible for the symptoms and whether stabilization is reasonably expected to provide meaningful benefit.

You don’t have to assume that lumbar fusion means a major spine operation.

If you have been told that you need lumbar fusion — or if chronic back and leg pain has persisted despite extensive treatment — you may have a less invasive option worth exploring.
