An annular tear sounds far worse than it is

The annulus is the disc's outer ring. A tear — many radiologists prefer "fissure" — is a small crack in that ring.

Why "fissure" is the better word

"Tear" implies trauma and rupture. Most of these are small, gradual cracks that develop with normal ageing, not the result of a single injury. Radiology guidance has moved toward "fissure" for exactly this reason.

Why it can be painful

The outer third of the annulus has a nerve supply. That is why a small crack there can hurt out of proportion to how it looks on a scan — a sensitive area, not a severe injury.

Healing

The annulus has limited blood supply, so healing is slow, but these fissures commonly become non-painful over time even when they remain visible on imaging.

The part that usually gets left out

Annular fissures are frequently found in people with no back pain whatsoever. Their presence on a report does not establish them as the source of symptoms.

What it does not mean

  • It does not mean the disc has ruptured.
  • It does not mean the disc is leaking or falling apart.
  • It does not mean you did something to break it.

When to stop reading and see someone

Seek urgent medical care

  • Loss of bladder or bowel control, or numbness around the groin and inner thighs (possible cauda equina syndrome)

See a professional before continuing

Most back pain is not dangerous. These signs, though, need a person — not a web page:

  • Pain after significant trauma — a fall or an accident
  • Neurological deficit: loss of strength, loss of sensation, or spreading numbness
  • Fever, chills, or signs of infection alongside back pain
  • Unexplained weight loss, or a history of cancer
  • Severe night pain that does not settle with rest
  • Pregnancy — back pain in pregnancy needs specialised guidance
  • Under 18 years old — this content is written for adults

This page explains the term. The app explains your report.

Every report is worded differently — the level, the wording, whether a nerve is involved. SpinalAI reads your own report and tells you what yours says, in plain English, in seconds.
