Lumbar disc herniation

Treatment in Pittsburgh, including endoscopic discectomy.

A herniated disc in the lower back is one of the most common — and one of the most treatable — causes of sciatica, leg pain, and back pain in adults. Most people get better without surgery. For the smaller number who don't, the choice of how surgery is performed matters more than is usually explained.

This page is meant to give you a clear picture of what a lumbar disc herniation actually is, what to expect from non-surgical care, and what your surgical options look like — including a less invasive approach that's available in Pittsburgh but not widely used here.

What is a lumbar disc herniation?

Between each pair of vertebrae in your lower back sits a disc — a cushion with a tough outer ring and a softer center. A herniation happens when part of the softer center pushes through the outer ring and presses against a nearby nerve.

The disc itself often doesn't hurt much. The real problem is usually the nerve. That's why a herniated disc most often shows up not as back pain, but as pain radiating down one leg — what most people call sciatica. You may also notice numbness, tingling, or weakness in a specific area of the leg or foot that follows the path of the affected nerve.

Most herniations occur at the lowest two levels of the spine (L4–L5 and L5–S1), which is why the pain is most often felt down the back of the thigh, the outside of the calf, or into the foot.

What most people experience — and why time matters

The most important thing to understand about a lumbar disc herniation is this: the majority of them get better on their own. Studies that follow people over time consistently show that pain, leg symptoms, and even the size of the herniation itself often decrease over weeks to months without any procedure at all.

For most patients, the right first step is a structured course of non-surgical care:

  • A focused course of physical therapy
  • Anti-inflammatory medication when appropriate
  • Activity modification — staying active without aggravating the nerve
  • An epidural steroid injection in selected cases, to calm nerve inflammation

Most people see meaningful improvement within six to twelve weeks. Some take longer. The point isn't to wait passively — it's to give the body a real chance to do what it usually does, while watching for the smaller number of situations where surgery becomes the better option.

When surgery is worth considering

Surgery for a herniated disc isn't about how much pain you've had. It's about whether your symptoms, your imaging, and your response to conservative care line up in a way that makes a procedure clearly more likely to help than continued non-surgical treatment.

Surgical evaluation is typically reasonable when:

  • Leg pain persists despite a real trial of non-surgical care
  • Pain is severe and not controlled with reasonable measures
  • There is progressive weakness in the leg or foot
  • Symptoms are interfering substantially with sleep, work, or daily function
  • Imaging shows a disc herniation that explains the symptoms

A few situations warrant urgent evaluation regardless of how long symptoms have been present: rapidly worsening weakness, loss of bladder or bowel control, or numbness in the area you would sit on. These can be signs of a more serious nerve compression and should be assessed immediately, often in an emergency setting.

Surgical options for a herniated disc

The goal of surgery for a lumbar disc herniation is straightforward: relieve the pressure on the nerve by removing the piece of disc that's pressing on it. The procedure is called a discectomy. What varies — and what's worth understanding before you choose a surgeon — is how the surgery is performed.

In Pittsburgh, you will generally encounter three approaches:

Open microdiscectomy

1–2 inch incision

The traditional approach. The muscles of the back are pulled aside to reach the disc. Effective, well-studied, and still the most commonly performed version in the region. Recovery typically involves a few weeks of activity restriction.

Tubular microdiscectomy

~1 inch incision

A smaller-incision variation. A narrow tube is passed through the muscle layers to create a working channel for the instruments. Less muscle disruption than a fully open approach, though the tube still spreads the muscle apart during the procedure.

Endoscopic discectomy

7-millimeter incision

The least invasive of the three. A small camera and specialized instruments pass between the muscle fibers, so the muscle is not cut or stripped. The surgeon works while watching a high-definition screen, with a gentle flow of fluid that keeps the view clear.

Each approach has appropriate uses. The right choice depends on the location of the herniation, the size and shape of the piece of disc pressing on the nerve, your anatomy, and your goals. What is consistent across the board is this: the less the surrounding muscle is disrupted, the faster most people recover.

Recovery after surgery

Recovery varies considerably depending on which approach is used. As a general rule, the less the surrounding muscle is disrupted during surgery, the faster most people return to normal activity. For an endoscopic discectomy, where the instruments pass between the muscle fibers, the typical course looks like this:

Day of surgery
The procedure takes roughly 45 minutes to an hour. You walk before going home. Most patients leave the surgery center within a couple of hours of finishing.
First week
Most patients describe leg pain as significantly improved within hours to days. Back soreness around the incision is usually mild and resolves quickly. Most do not require narcotic pain medication beyond the first day or two, if at all.
Return to desk-type work
Often within a few days, depending on how you feel.
Return to walking and gentle activity
Generally encouraged from day one.
Return to higher-impact activity, lifting, and sports
Typically by four to six weeks, guided by your individual progress.

Recovery from open or tubular microdiscectomy follows a similar pattern but generally takes longer — both because the soft-tissue work is more substantial and because the muscle envelope itself needs to heal.

Choosing an approach

Choosing among these approaches isn't a decision to make from a website. It depends on the location of the herniation, the size and shape of the piece of disc that's pressing on the nerve, your anatomy, your symptoms, your goals, and how you've responded to non-surgical care. The same finding on an MRI can have a different best answer for two different people.

Endoscopic spine surgery is the focus of my practice. If you're working through a herniated disc and trying to understand which approach makes sense for your situation, I'd be glad to discuss the options at an appointment.
