Understanding Spinal Decompression
This article explains spinal decompression for general understanding. It does not describe a treatment offered by Clinic 27.
What does spinal decompression mean?
The term can refer to different procedures. Surgical decompression is an operation to relieve pressure on nerves. Non-surgical decompression is a term sometimes used to market spinal traction, which applies a pulling force to the spine. These approaches differ in how they are performed and in the evidence supporting their use.
Understanding which procedure a source is discussing matters when reading about potential benefits, risks or recovery.
Surgical spinal decompression
Lumbar decompression surgery takes place in hospital and aims to relieve symptoms associated with compressed nerves in the lower spine. Depending on the condition, a surgeon may remove part of a vertebral bone or disc to create more space around affected nerves.
The NHS overview of lumbar decompression surgery explains the conditions it may be used for, what an operation involves and possible complications. Suitability, alternatives and recovery are discussed with the surgical team; an online article cannot determine whether an operation is appropriate for an individual.
Non-surgical decompression and traction
Traction uses a pulling force, applied manually or with equipment. The label “non-surgical decompression” should not be read as evidence that a treatment will repair a disc, return it permanently to a particular position or provide lasting pain relief.
A Cochrane review of traction for low-back pain, published in 2013 with searches through August 2012, found little or no improvement in pain or function for the populations studied, including people with sciatica. The authors also identified limitations in the evidence.
The UK’s NICE guideline NG59, recommendation 1.2.6, recommends against traction for managing low-back pain, with or without sciatica. This recommendation concerns traction for that condition; it is separate from decisions about spinal surgery.
Questions to ask when reading treatment claims
- Is the information about an operation, manual traction or a particular device?
- Does the research concern the same condition and procedure being discussed?
- What benefits, uncertainties, risks and alternatives are explained?
- Are results described as possibilities, or presented as guarantees?
