In plain language
No new bone injury — no fracture, no dislocation, nothing that happened recently. It is the sentence that answers the question most bone X-rays are ordered to answer, and it is good news.
Upload your MRI, CT or X-ray — de-identified in your browser — and every finding is mapped onto your images and explained without jargon.
Where you'll see this
The impression of almost every X-ray or CT done after an injury.
Your report may word it “No acute osseous abnormality identified”, “No acute fracture or dislocation” or “Osseous structures are intact”. These mean the same thing.
Questions worth asking your doctor
- Does this wording mean you are unsure, or that you are reasonably confident and being careful?
- If something cannot be ruled out from this scan, what would rule it out?
- Is there anything here you would act on today?
How often does this turn up?
This is one of the most frequently written sentences in all of radiology, because most bone X-rays are done after an injury and most of them find nothing broken. It is the direct answer to the question the scan was ordered to ask. It appears constantly on reports of wrists, ankles, ribs, spines and skulls, and its flat wording is what makes readers uneasy about what is, in fact, the best possible outcome.
Does it mean something is wrong?
Taken at face value it is reassurance, and it should be read as such: no fracture, no dislocation, nothing new in the bone. Two limits are worth knowing rather than worrying about. Acute means recent, so the sentence is silent about long-standing changes such as arthritis, which the report will describe separately if present. And some fractures are genuinely invisible in the first days — scaphoid fractures in the wrist and hip fractures in older people are the classic examples — which is why a doctor may treat a convincing injury as a fracture despite a clear X-ray, and rescan or use a different test later.
What to do with it
For most injuries the sentence closes the question and treatment is whatever the soft tissues need: rest, ice, pain relief, and time. Where the examination strongly suggests a fracture the X-ray did not show, the normal path is a repeat X-ray after ten to fourteen days, or an MRI or CT that can see what plain films cannot. If your pain is not settling as expected, that is worth reporting rather than assuming the clear X-ray settled it.
Frequently asked questions
- Does no acute osseous abnormality mean nothing is broken?
- It means no fracture or dislocation was visible on these images. That is the same thing in the great majority of cases, but it is not an absolute guarantee — a few fracture types do not show up straight away, which is why doctors sometimes treat the injury and re-image later.
- What does acute mean here?
- Recent. The word restricts the statement to new injury, which is what the scan was looking for. It is deliberately silent about chronic findings such as arthritis or old healed fractures; if those are present, the report describes them in their own sentence.
- My X-ray was clear but it still hurts. Why?
- Because X-rays show bone well and soft tissue poorly. Sprains, ligament and tendon injuries, bruising and cartilage damage all hurt a great deal and leave a normal-looking film. A clear X-ray rules out a broken bone; it does not rule out a real injury.
