Most articles about spinal decompression focus on who benefits from the treatment. This one focuses on who does not. It is a shorter list than the “who benefits” side, but it is a more important one, because getting the wrong treatment for the right reason produces poor outcomes, and getting a treatment when you have a medical condition that makes it contraindicated can produce genuinely bad ones.
Marketing rarely dwells on contraindications. Most decompression websites gloss over the “not everyone is a candidate” reality because it complicates the sales message. But the honest reality is that spinal decompression, like every effective medical intervention, has specific conditions under which it should not be performed. Understanding those conditions is part of taking your spine seriously.
At Citrin Chiropractic Center in St. Louis, screening every patient for contraindications is the first step of the initial evaluation, before anyone gets on a decompression table. This article walks through what those contraindications are, why each one matters, and what alternatives exist for patients who are not candidates. Understanding this is part of making an informed decision about your care.
Why Contraindications Matter
Contraindications are medical conditions or circumstances under which a specific treatment should not be performed because the risks outweigh the benefits, or because the treatment could cause harm. In spinal decompression, contraindications fall into two categories. Absolute contraindications mean decompression is off the table entirely, no exceptions. Relative contraindications mean decompression can potentially be done but with modifications, extra caution, or after specific conditions are met.
The reason a thorough screening matters is that many contraindications are conditions patients do not know they have. Osteoporosis in a 60-year-old who has never had a bone density scan. Undiagnosed hypertension. A hairline fracture from a fall the patient did not think much of. A mass or lesion showing up incidentally on imaging that was ordered for something else. Screening catches these before a treatment happens that could exacerbate an underlying problem.
Clinics that skip the screening, or that treat patients regardless of contraindications, are cutting the corner where safety lives. Even when nothing bad happens, cutting that corner is not defensible practice.
Absolute Contraindications: When Decompression Is Off the Table
These conditions rule out spinal decompression entirely. If any of these apply to you, decompression is not the right treatment and no responsible provider will offer it.
Spinal Fracture (Recent or Unhealed)
Applying traction force to a fractured vertebra can worsen the fracture and, in severe cases, cause displacement that damages the spinal cord. Any recent trauma to the spine requires imaging to rule out fracture before any traction-based treatment is considered. Patients with previously fractured vertebrae that have not fully healed are similarly not candidates until healing is confirmed.
Malignancy (Cancer) in the Spine or Nearby Structures
Applying traction to a spine affected by a tumor or metastatic disease can produce fracture, displacement, or spread. Patients with active malignancy involving the spine are not candidates. Patients with a history of cancer that could have spread to bone require imaging clearance before decompression is considered.
Spinal Infection (Osteomyelitis or Discitis)
Active infection of the spine or the discs creates fragile tissue that can be significantly damaged by traction. It also creates the possibility of spreading infection through the vertebral column. Any suspected spinal infection is worked up and resolved before decompression is even discussed.
Severe Osteoporosis
Severely osteoporotic vertebrae can fracture under traction forces that healthy bone tolerates easily. Patients with confirmed severe osteoporosis, particularly older patients on medications for bone loss, are not decompression candidates. Bone density testing may be indicated before treatment for at-risk patients.
Aortic Aneurysm
Applying traction to a spine near an aortic aneurysm can put additional stress on the aneurysm wall, potentially causing dissection or rupture. Any patient with a known aortic aneurysm is not a decompression candidate. Patients with risk factors for aneurysm (older age, hypertension, family history, connective tissue disorders) should have this ruled out before treatment.
Cauda Equina Syndrome
Loss of bowel or bladder control, saddle anesthesia (loss of sensation in the area that would touch a saddle), or severe progressive leg weakness following a disc injury is a surgical emergency requiring immediate operative decompression, not conservative care. Applying non-surgical decompression to a patient with cauda equina syndrome delays the surgery they urgently need.
Spinal Cord Compression with Progressive Neurological Deficits
Progressive weakness, loss of sensation, or worsening neurological function indicates active spinal cord compromise that requires surgical rather than conservative management. These patients need urgent neurosurgical evaluation, not decompression therapy.
Pregnancy
The mechanical forces of decompression, combined with the physiological changes of pregnancy (relaxin softening ligaments, altered spinal mechanics), make lumbar decompression inappropriate during pregnancy. Cervical decompression is similarly avoided in most cases. Pregnant patients with back or neck pain have safer alternatives available.
The pattern to remember: if any of the above absolute contraindications apply to you, no responsible provider will offer decompression, regardless of how badly you want the treatment or how appealing the marketing sounds. Alternative treatments exist and produce better outcomes than pushing through an inappropriate intervention.
Relative Contraindications: Proceed With Caution
These conditions do not automatically rule out decompression but require careful consideration, protocol modifications, or specific pre-treatment steps.
Spinal Fusion Hardware
Decompression at a fused spinal level is generally not helpful (the fused segment cannot decompress in the intended way) and can create excessive stress on the hardware or adjacent segments. Decompression above or below a fusion is sometimes appropriate to address adjacent segment disease, but requires specific evaluation of the hardware location and stability.
Recent Spinal Surgery
Patients who have had recent spinal surgery need adequate healing time before decompression is considered. The specific waiting period depends on the type of surgery, and the treating surgeon’s clearance is required before starting decompression on a post-surgical spine.
Moderate Osteoporosis
Unlike severe osteoporosis (absolute contraindication), moderate osteoporosis may allow modified decompression protocols with reduced force parameters and careful monitoring. This decision depends on the specific bone density, patient age, and the condition being treated.
Severe Obesity
Very high body weight can exceed decompression table specifications and complicates the mechanical delivery of appropriate force. Some patients in this category are still candidates with modified protocols; others benefit from alternative treatments as a first step, with decompression as a possibility later after weight management.
Uncontrolled Hypertension
Patients with poorly controlled high blood pressure may need cardiovascular clearance before decompression. Once blood pressure is well-managed, treatment can typically proceed normally.
Anticoagulant (Blood Thinner) Medications
Patients on blood thinners generally can still receive decompression, but the physician needs to know about the medication and factor it into the treatment plan. Communication between the decompression provider and the prescribing physician is standard.
Severe Anxiety or Claustrophobia About Being Restrained
Decompression involves being secured to a table with harnesses. Patients with severe anxiety about this can sometimes still complete treatment with proper explanation, pacing, and support, but honest discussion of this concern up front lets the team accommodate appropriately.
Certain Cardiac Conditions
Patients with significant cardiovascular disease may need cardiology clearance before decompression, particularly those with implantable devices or unstable cardiac conditions. Once cleared, treatment usually proceeds without issue.
Special Considerations by Population
Pregnancy and Postpartum
Decompression is not offered during pregnancy. Postpartum patients can typically be evaluated once the immediate recovery period is complete and, if breastfeeding, hormonal changes have stabilized. Back pain during and after pregnancy is common and has good treatment alternatives that do not involve decompression, our office coordinates care with obstetric providers as needed.
Older Adults
Age itself is not a contraindication. Many decompression patients are in their 60s, 70s, or older. What matters at older ages is proper screening for the conditions that become more common with age, osteoporosis, cardiovascular disease, aortic aneurysm, spinal degeneration, cancer history. Once those are ruled out or addressed, decompression can be an excellent option for older adults with disc-related pain.
Post-Surgical Patients
Patients with prior spinal surgery need case-by-case evaluation. Adjacent segment disease (degeneration above or below a fused level) is a common indication for decompression in post-surgical patients, but the fusion hardware itself changes what can and cannot be done. The treating surgeon’s involvement in the decision is often appropriate.
Athletes and Highly Active Patients
No specific contraindications, but athletes often want to return to full activity faster than decompression alone accommodates. Integrating decompression with sports-specific rehabilitation produces the best outcomes for this population.
How Our Office Screens Every Decompression Patient
The initial evaluation at our office is designed to catch contraindications before they become problems. The screening process includes:
- Comprehensive medical history: prior surgeries, current medications, existing medical conditions, cancer history, cardiovascular history, bone health, current pregnancy status
- Physical examination: assessment of the spine, palpation for tenderness that could indicate fracture, neurological testing for cauda equina or progressive deficits
- Imaging review: if you have prior X-rays or MRIs, we review them. If imaging is needed to rule out contraindications, we order it before treatment
- Coordination with other providers: if your history suggests we need clearance from your primary care physician, cardiologist, or oncologist, we obtain it before proceeding
- Bone density considerations: for older patients or those with risk factors, bone density testing may be requested if not already done
- Ongoing monitoring: during treatment, patient response is monitored session to session, and any concerning symptoms trigger reassessment
This is not a formality. Contraindications are the reason a proper evaluation happens before any treatment begins. Patients who pass the screening can proceed with confidence that decompression is appropriate for them. Patients who do not pass the screening get the honest answer that decompression is not their right treatment, along with a discussion of what alternatives exist.
What to Do If You Have a Contraindication
Being ruled out for decompression is not the end of your treatment options. It just means decompression is not the right tool for your specific case. Alternative approaches include the following.
Chiropractic adjustment, when appropriate for the condition, produces good outcomes for many spinal complaints without the specific forces that make decompression contraindicated for certain patients. Medical massage therapy addresses muscle tension, fascial restriction, and soft tissue components of pain without any traction-based intervention. Active rehabilitation, targeted strengthening, and postural training address the biomechanical contributors to pain. For patients with true disc problems who are not decompression candidates, our disc injury care and back pain treatment programs use approaches specifically appropriate for each patient’s clinical picture. For patients where surgery becomes appropriate, coordination with surgical specialists is part of what we do.

Our office serves patients from across the St. Louis metro, including from Florissant, Clayton, Maryland Heights, University City, Ferguson, and beyond. Whether decompression turns out to be the right treatment for your specific case or something else is, our evaluation gives you an honest answer along with the right care plan. For patients whose pain came from an auto accident, the auto accident treatment approach and insurance coverage guide lay out the care and payment pathways.
Frequently Asked Questions
Who should not get spinal decompression?
Patients with spinal fracture, spinal malignancy, spinal infection, severe osteoporosis, aortic aneurysm, cauda equina syndrome, progressive neurological deficits, or pregnancy should not receive spinal decompression. Patients with spinal fusion hardware, moderate osteoporosis, severe obesity, uncontrolled hypertension, blood thinner medications, or certain cardiac conditions may still be candidates with modifications or clearance from other providers.
Can I get spinal decompression while pregnant?
No. The mechanical forces of decompression combined with the physiological changes of pregnancy make lumbar decompression inappropriate during pregnancy, and cervical decompression is similarly avoided. Pregnancy back pain has good alternative treatments that do not involve traction, our office can coordinate this care with your obstetric provider.
Is spinal decompression safe if I have osteoporosis?
Severe osteoporosis is a reason not to have decompression, because osteoporotic vertebrae can fracture under traction. Moderate osteoporosis may allow modified protocols with reduced force. Bone density testing may be requested before treatment for patients at risk, and the decision is made based on specific findings rather than a blanket rule.
Can I get decompression if I have had spinal fusion surgery?
Decompression at the fused level itself is not helpful. Decompression above or below a fusion is sometimes appropriate for adjacent segment disease, but requires specific evaluation of hardware location, stability, and how long ago the surgery was performed. Coordination with the treating surgeon is often part of that decision.
Am I too old for spinal decompression?
Age itself is not a contraindication. Many decompression patients are in their 60s, 70s, or older. What matters at older ages is proper screening for the medical conditions that become more common with age, osteoporosis, cardiovascular disease, aortic aneurysm, cancer history. Once those are cleared, decompression is often an excellent option.
What if I am on blood thinners?
Blood thinner medications are generally not an absolute contraindication, but the physician needs to know about them and factor them into the treatment plan. Communication with your prescribing physician about the treatment is standard practice.
What happens if I have decompression when I should not have?
Depending on the specific contraindication, potential consequences range from mild worsening of symptoms (in the case of certain relative contraindications) to serious harm (in cases of undiagnosed fracture, malignancy, or aortic aneurysm). This is why proper screening is not optional. Providers who cut this corner are putting patients at risk that a proper evaluation would have caught.
How do I know if I have contraindications I do not know about?
Many contraindications only become apparent through proper history-taking, examination, and sometimes imaging. This is exactly what the initial evaluation is designed to catch. If you have never had a bone density scan, no known cardiovascular disease, and no history of cancer, most of the common absolute contraindications can be reasonably ruled out by history and physical alone. When your history raises specific concerns, additional testing is used to clarify before treatment begins.
