The Clinical Picture

The Case for Trying Decompression First

Non-surgical spinal decompression therapy is a clinically recognised treatment for herniated discs, bulging discs, sciatica, and degenerative disc disease. It works by creating negative intradiscal pressure — gently pulling the spine to retract disc material and restore disc height and hydration. For many patients with disc-related back pain, decompression therapy achieves results comparable to surgery, without the risks, recovery time, or cost.

Back surgery in New Zealand is not a small decision. Depending on the procedure, it carries real risks — infection, nerve damage, hardware failure, adjacent segment disease, and a recovery period that can last three to six months. It also costs between $15,000 and $50,000 in the private system, or requires months on a public waitlist.

Most orthopaedic surgeons in New Zealand will recommend a period of conservative management — including physiotherapy, chiropractic, and decompression therapy — before recommending elective spinal surgery for non-emergency conditions. This guide explains what that means in practice.

Important: Some conditions require urgent surgical assessment Cauda equina syndrome (bowel or bladder dysfunction with back pain) is a surgical emergency. If you are experiencing these symptoms, do not delay — go to your nearest emergency department immediately.
How It Works

The Win Trac 100 System — Explained Simply

The Win Trac 100 is a computerised decompression table used at Auckland Wellness Centre. Here is what actually happens during treatment.

What Happens to Your Disc

Herniated disc material compresses nerves. Decompression creates negative pressure to retract it.

PositioningPatient lies on the Win Trac 100 table. A pelvic harness is secured.
Controlled TractionComputer applies graduated traction — increasing to a target force, then releasing rhythmically.
Negative PressureIntermittent distraction creates negative intradiscal pressure, drawing disc material inward.
20–30 MinutesEach session lasts 20–30 minutes. Most patients report relief or relaxation during the session.
Clinical Decision Guide

When Surgery is Needed — and When It Is Not

Honest clinical guidance on the four categories of back pain patients.

Surgery Urgent

Seek surgical assessment immediately

  • Cauda equina syndrome (bowel/bladder dysfunction)
  • Progressive neurological deficit — worsening weakness
  • Loss of sensation in legs or groin area
  • Spinal fracture or instability
  • Spinal tumour or infection confirmed on MRI
Consider Surgery

Conservative care has failed after adequate trial

  • 6–12 weeks of conservative care with no improvement
  • Significant quality-of-life impact from pain
  • Severe stenosis confirmed on imaging
  • Large disc herniation not responding to treatment
Try Decompression First

Good candidates for non-surgical decompression

  • Herniated or bulging disc with nerve pain
  • Sciatica caused by disc compression
  • Degenerative disc disease with pain
  • No surgery recommended yet by specialist
  • Wanting to avoid surgery if possible
Decompression Works Best

Conditions with strong evidence for decompression

  • Acute disc herniation — within 3 months
  • Sciatica with pain into one leg (radiculopathy)
  • Posterior facet syndrome
  • Cervical disc pain with arm symptoms
  • Post-surgical disc pain (at non-operated levels)
Patient Decision Framework

Spinal Decompression vs Surgery — Side by Side

A structured comparison across the factors that matter most to patients making this decision.

Factor Spinal Decompression Back Surgery
Anaesthetic Required ✓ No ✗ Yes — general or spinal
Recovery Time ✓ None — return to normal activities same day ✗ 6–12 weeks minimum
Cost (NZD) ✓ $30–$50 per session ($360–$1,000 full course) ✗ $15,000–$50,000+
ACC Coverage ✓ Yes — $30/session if injury qualifies — Partially via public system (long wait)
Risk of Complications ✓ Very low ✗ Infection, nerve damage, hardware failure
Reversible ✓ Yes — no permanent changes to spine ✗ No — structural changes are permanent
Treatment Duration 12–20 sessions over 4–6 weeks One procedure + 6–12 weeks rehab
Waiting Time in NZ (Public) ✓ Appointment within days ✗ Often 6–18 months
Suitable for All Disc Conditions — Not suitable for all cases — Not suitable for all cases

For Best Outcomes

Key Success Factors for Decompression Therapy

Decompression therapy works best when these conditions are met.

Correct Diagnosis

Decompression works for disc-related conditions — herniation, bulge, degenerative disc. A clinical assessment and imaging review ensures you are a suitable candidate before treatment begins.

Starting Early

Acute disc herniations respond best to early intervention. The longer a disc herniation is left untreated, the more scar tissue and chronic inflammation develop. Starting within weeks of injury leads to better outcomes.

Full Course of Treatment

Disc rehydration and retraction take time. Most successful outcomes occur after 12–20 sessions over 4–6 weeks. Stopping after 3–4 sessions because of early improvement often leads to relapse.

Combined Rehabilitation

Decompression works best when combined with chiropractic adjustments, core strengthening exercises, and postural correction. At AWC, decompression is part of an integrated treatment plan — not a standalone session.

No Contraindications

Decompression is not suitable for patients with spinal fractures, severe osteoporosis, spinal hardware, tumours, or during pregnancy. A thorough assessment rules these out before treatment starts.

Monitored Progress

Regular progress reviews with your chiropractor allow the treatment plan to be adjusted. If decompression is not achieving adequate improvement after the first several sessions, your chiropractor will discuss next steps including specialist referral.

Your Questions

Frequently Asked Questions

What is spinal decompression therapy?
Spinal decompression therapy is a non-surgical treatment for disc-related back and neck pain. It uses a motorised table to gently stretch the spine, creating negative intradiscal pressure that draws herniated or bulging disc material back toward the centre and encourages rehydration of the disc. At Auckland Wellness Centre, we use the Win Trac 100 system.
How does the Win Trac 100 spinal decompression system work?
The Win Trac 100 is a computerised decompression table. You are positioned face-up and secured with a pelvic harness. The computer applies precisely controlled rhythmic traction — gradually increasing to a target force, then releasing. This cycle creates negative intradiscal pressure. Sessions last 20–30 minutes and are generally comfortable.
When is back surgery actually necessary?
Surgery is urgent for cauda equina syndrome (bowel/bladder dysfunction), progressive neurological deficit (worsening weakness), and spinal instability. For most other conditions — disc herniations, sciatica, degenerative disc disease — surgery is considered after an adequate trial of conservative care (typically 6–12 weeks) has not produced sufficient improvement.
How much does spinal decompression cost vs back surgery?
Spinal decompression at Auckland Wellness Centre costs $30/session (ACC) or $50/session (private). A 12-session course costs $360–$600. Back surgery in the NZ private system ranges from approximately $15,000 for a simple discectomy to $50,000+ for complex multi-level fusion — plus rehabilitation costs.
Is spinal decompression safe?
Yes, when performed on appropriate candidates. Decompression is not suitable for patients with spinal fractures, severe osteoporosis, spinal tumours, spinal hardware, or during pregnancy. We conduct a thorough clinical assessment before recommending treatment.
What conditions does spinal decompression treat?
Spinal decompression is primarily used for herniated and bulging discs (lumbar and cervical), sciatica caused by disc compression, degenerative disc disease, posterior facet syndrome, and radiculopathy — nerve pain radiating into the arm or leg from a compressed spinal nerve.
Does ACC cover spinal decompression in Auckland?
Yes. Spinal decompression is covered by ACC when there is a qualifying injury cause. The co-payment at Auckland Wellness Centre is $30 per session. Private sessions (without ACC) are $50 per session.
