What decompression involves
A traction table applies a controlled pulling force while you are positioned and supported. This is nonsurgical treatment, not surgical decompression. Your clinician should explain positioning, what you may feel and how to stop the session if symptoms increase. A scan showing a disc change does not by itself establish that traction will help.
Selection and safety matter
Discuss previous spine surgery, fractures, osteoporosis, cancer, pregnancy and any new neurological symptoms before treatment. Some conditions make traction unsuitable or require medical clearance. Progressive weakness, bladder or bowel changes, or numbness around the groin require urgent medical assessment rather than a routine decompression appointment.
Be clear about the limitations
Evidence for nonsurgical decompression or traction is limited and inconsistent. NICE guidance recommends against traction for low-back pain with or without sciatica. There is no guarantee that a disc will retract, heal or avoid surgery. If decompression is discussed, ask why it is being considered for your particular presentation and how it compares with active rehabilitation and other options.
Ask about the whole plan
Discuss a defined trial, meaningful functional goals and when to stop if there is no benefit. Decompression should not become a substitute for appropriate exercise, medical evaluation or referral. Ask separately about session costs and insurance: a covered chiropractic benefit does not mean decompression is covered.

Your questions, answered
Is this the same as spine surgery?
No. Nonsurgical decompression uses traction. It does not remove tissue or surgically free a nerve.
Will my insurance cover it?
Do not assume so. Coverage varies by plan and service; Original Medicare does not broadly cover additional services furnished by a chiropractor. Ask for a written estimate before starting.
