Surgery is only one of many options for your spine.

Most back and neck problems get better without an operation. So when you come see me, we start with the things that carry the least risk: physical therapy, targeted injections, changes to how you move and work — and give them a real chance to help.

If it turns out you do need surgery, you'll know exactly why, and I'll use the least invasive approach that solves the problem. I trained at one of the highest-volume spine programs in the country, and I bring that same standard to every case here in the Inland Empire.

We decide together

You know your life better than I do. I'll lay out the options honestly — what each one involves and what it won't fix — and we'll choose based on what matters to you.

Plain language, always

I'll show you your imaging, point to what's going on, and explain it without the jargon. When you leave, you should actually understand what's happening in your spine.

Least intervention first

The spine often settles down with time and the right non-surgical care. I keep surgery in reserve for when those options have genuinely run their course.

Evidence-Based Practice

As an active researcher and peer reviewer for The Spine Journal and JBJS, my recommendations reflect the current best evidence in spine care.

Conditions & care

What I treat, and how I treat it.

Conditions I treat

These are the problems I see most often across the neck and back. If you're not sure what's causing your pain, that's exactly what a visit is for.

Degenerative Spine Conditions

The everyday wear-and-tear problems of the spine — disc degeneration, arthritis, and the pain and stiffness that come with them.

Herniated DiscSciaticaDegenerative Disc Disease

Spinal Stenosis

Narrowing of the spinal canal that pinches the nerves, often causing leg pain, numbness, or cramping that worsens with walking or standing.

Lumbar StenosisCervical StenosisNeurogenic Claudication

Spondylolisthesis

When one vertebra slips forward on another, causing back pain and nerve symptoms. Both the degenerative and isthmic types.

Slipped VertebraInstabilityLow Back Pain

Myelopathy & Radiculopathy

Nerve and spinal cord compression — from a pinched nerve causing arm or leg symptoms, to cord compression affecting balance and coordination.

Pinched NerveCervical MyelopathyNeck & Arm Pain

Scoliosis & Adult Deformity

Curvature and imbalance of the spine in adults and adolescents — a particular area of my subspecialty training.

Adult ScoliosisKyphosisSagittal Imbalance

Spinal Fractures & Trauma

Vertebral fractures from osteoporosis, injury, or high-energy trauma, evaluated and treated with the full range of modern options.

Compression FractureVertebral FractureKyphoplasty

How I treat them

When surgery is the right answer, these are the approaches I bring to it — chosen to solve the problem with the least disruption possible.

Minimally Invasive Spine Surgery

Muscle-sparing techniques through small incisions, using tubular retractors and advanced imaging to reduce pain, blood loss, and recovery time.

MIS TLIFMicrodiscectomySmall Incision

Endoscopic Spine Surgery

Among the least invasive options available — treating disc and nerve problems through an incision smaller than a fingertip, often as an outpatient.

OutpatientFast RecoveryDay Surgery

Navigation-Assisted Surgery

Real-time 3D navigation guides every screw and implant with sub-millimeter accuracy — the same technology used at the highest-volume spine centers, for safer, more precise results.

Computer Navigation3D ImagingPrecision

Deformity Correction

Three-dimensional correction of scoliosis and spinal imbalance, restoring alignment and posture — among the most complex work in spine surgery.

Scoliosis SurgerySpinal AlignmentReconstruction

Revision Spine Surgery

When a previous surgery hasn't worked, I reassess from first principles — hardware failure, adjacent segment problems, pseudarthrosis, and failed back surgery.

Failed Back SurgeryHardware RevisionSecond Opinion

Motion-Preserving Surgery

Where appropriate, disc replacement and motion-sparing procedures that relieve symptoms while preserving the spine's natural movement.

Where I trained, and why it matters.

I'm a fellowship-trained orthopaedic spine surgeon, and I see patients across Rancho Cucamonga, Chino Hills, Riverside, and Redlands.

I did my spine fellowship at Twin Cities Spine Center in Minneapolis — one of the busiest spine programs in the country. That's where I trained on the hardest deformity reconstructions alongside the newest minimally invasive techniques, so I'm comfortable across the full range of what a spine can need.

Before that, I studied neuroscience at UCLA and earned my MD at Drexel. I still keep a hand in research — spinal implants, surgical navigation, disc replacement, and biomechanics — and I review papers for two of the field's major journals. It keeps my practice grounded in what the evidence actually shows.

I also teach — I'm on faculty at California University of Science and Medicine, and mentoring the next group of physicians is one of the parts of this work I enjoy most.

Let's make sense of what's going on.

Here are some of the problems I treat most often. Tap any one to read about what causes it, what it feels like, and how it's usually treated — surgery included, but rarely first.

Read the full patient guide: Understanding Your Spine →

Lumbar Disc Herniation

A common cause of low back pain and sciatica — when disc material presses on a spinal nerve.

What it is: The soft inner core of a spinal disc pushes through its tougher outer layer, often irritating a nearby nerve root and causing radiating pain, numbness, or weakness down the leg (sciatica).

Conservative treatment (tried first):

  • Physical therapy and core strengthening
  • Anti-inflammatory medications (NSAIDs)
  • Epidural steroid injections for nerve pain
  • Activity modification and time (most resolve in 6–12 weeks)

When surgery is considered: Progressive neurological deficits, loss of bowel/bladder control, or failure of 6+ weeks of conservative care. Microdiscectomy is minimally invasive with rapid recovery.

Spinal Stenosis

Narrowing of the spinal canal that compresses nerves, causing pain, cramping, or weakness — often with walking.

What it is: Age-related changes (bone spurs, thickened ligaments, disc bulging) gradually narrow the canal, compressing the nerves inside. Classic symptom is neurogenic claudication — leg pain that worsens with walking and improves with sitting.

Conservative treatment (tried first):

  • Physical therapy focused on flexion-based exercise
  • Epidural steroid injections
  • Activity modification
  • Pain management

When surgery is considered: Significant functional limitation despite conservative care. Minimally invasive decompression relieves pressure while preserving spinal stability.

Learn more ↓

Spondylolisthesis

A vertebra slips forward over the one below it, causing back pain and sometimes leg symptoms.

What it is: One vertebra slides forward relative to the adjacent vertebra. Can be degenerative, isthmic (stress fracture), or traumatic. Symptoms range from back pain alone to leg pain and weakness.

Conservative treatment (tried first):

  • Physical therapy and core/hip strengthening
  • Activity modification
  • Epidural or medial branch block injections
  • Bracing for select cases

When surgery is considered: High-grade slippage, progressive neurological symptoms, or failure of conservative care. MIS TLIF is highly effective with short hospital stays.

Adult Spinal Deformity

Scoliosis and kyphosis in adulthood causing pain, imbalance, or difficulty standing upright.

What it is: Abnormal curvature of the adult spine causing chronic back pain, difficulty walking, and a forward-stooped posture. Can be de novo degenerative scoliosis or progression of adolescent curves.

Conservative treatment (tried first):

  • Physical therapy for posture and core strengthening
  • Pain management and injections
  • Activity modification

When surgery is considered: Significant functional impairment, progressive neurological deficit, or inability to stand upright. Complex deformity surgery is an area of particular subspecialty focus for Dr. Acosta.

Learn more ↓

Cervical Disc Disease

Neck pain and arm symptoms from disc degeneration or herniation in the cervical spine.

What it is: Disc herniation or degenerative changes in the neck can compress nerve roots (radiculopathy: arm pain/numbness/weakness) or the spinal cord itself (myelopathy — requires prompt attention).

Conservative treatment (tried first):

  • Physical therapy and cervical traction
  • Anti-inflammatory medications
  • Cervical epidural steroid injections
  • Cervical collar for acute flares

When surgery is considered: Myelopathy often requires prompt surgery. For radiculopathy, surgery is considered after failure of conservative care. Both ACDF and cervical disc arthroplasty are options depending on the patient.

Research

Research and Publications

I keep an active research agenda — spinal implants, surgical navigation, motion-preserving procedures, and outcomes. I also review manuscripts for two of the field's leading journals.

It's not academic for its own sake — staying close to the research is how I make sure what I offer you reflects what actually works.
