discerning Sprain vs. Broken vs. Dislocated

[ryujinn]

Hello all,

I was just curious as to how you recognize a sprain vs. a break. To me, it's just hard to tell. Angle of rotation? Can you tell by their pain when you start touching it? Is there a point where you can tell by your application of pressure that it would be a break or a sprain? (of course aside from the obvious like a open fracture or such). Dislocation I'm sure if you'd see weird orientation or for example one shoulder uneven with the other because it popped out of its sockets, etc.

Or is it impossible to completely discern because we don't have x-rays on the field? But I guess I am just asking how can I measure the severity of a ankle/arm/etc. injury by just touch, asking questions, color, pulse, motor, sensory, etc.

Thank you for the tips! I look forward to hearing your responses.

You just listed all the ways you would evaluate it. You already know. ^_^

Unless its obvious, then its not. They will need an X-ray.

With most a lot of breaks and dislocations there is an obvious angle or length to the area, that makes you think, "Well that should be".

Break mostly hurt more than sprains, for the most part, but everyone's different and pain is subjective.

Numbness/Parasthesia is typically associated with a break rather than a strain.

Typically a sprain can be moved and stood on with discomfort. A break, however, will generally cause unbearable pain.

Always a good idea to check the pedal and tibialis pulses with any injury to the legs.

That being said, none of what I have listed is definitive. Minor fractures to the tarsals might present like a sprain, but I don't know, I'm not orthopaedic surgeon, just don't go taking 'rules' like the above to be absolute.

Femur fx's-check for shortening and rotation.

Good ones.

Following with a dustpan...
There are sprains, strains, dislocs and fx's. At the curb, in the living room or the field, note mech of injury for he folks at the ER.

Remember what my EMT instructor said, "Don't get on your radio telling me from the field about the tib fib spiral fracture or whatever, if it's broke, it's broke and you splint it" or some such.

None will be harmed by judicious splinting. Most will do better with local cooling, but do not cause cold injuries (i.e., put cold sources under a splint or large obscuring bandage).
"Judicious splinting" means following your protocols, but remembering:
A. "Splinting where it lies", if effective and practicable for pt movement, is an example of "Do no harm". That damage is already done, splinting in the field is not treatment but preventing harm and alleviating pain while transporting.
B. It is possible to splint so well that you cannot move the pt.
C. Padding, padding, padding. In fact, a beanbag or pillow with ties or ductape can be your best field splint for wrists and ankles and distal.
D. Distal S/S and c/o and "target fixation": Don't be so fixated on that fx stepoff that you miss the cold white foot or hand distal to it. What can you do about that? Make sure your splint has not turned into a TK from swelling or pt movement, etc.

Femurs will do best with traction splint all other factors being in favor of it (i.e., pelvis not fx and other injuries not impeding the application of straps needed to make the splint work, spinal and more-life threatening injuries being treated first).

Google "Ottawa Rules for Xray", especially wikipedia, for more on DDX for fx versus non-fx (actually, more aimed to let a doc know when to xray and when to maybe not xray).

I just want to add that the last femur fracture I had got so much relief from the traction splint he refused IV pain meds.

Ask the pt if they have broken a bone before, and how the current injury compares. While not definitive by any means, some people flat out know when something is broken. If I have a pt that has broken a bone before and tells me "I think it's broken" I tend to trust them on it.

 

[mycrofft]

Lookingat my sweepings above...

It looks oxymoronic to refer to splinting and pt movement in one sentence.
I meant moving the pt from the scene.:blush:

Any of our bush medics have something to say about practical ortho DDX and movement off the beaten path?

I've noticed the word "refused" gets used alot in EMS and it usually follows with some negative meaning especially if used in medical documentation with will need to be explained further.

When assessing for pain, there should be some quantifying or assessment system in place to allow for discision making based on patient need. The word "refused" should be reserved for the times a patient states they do not want a treatment or therapy that is ordered or warranted. However, if you are the one who believes the patient should take the pain medication and the patient "refuses", you should do adequate documentation as to why you felt the pain medication was necessary be it objective or subjective.

I would just put the pt declined IV meds.

 

[Seaglass]

This one's pretty obvious, but since nobody's mentioned it, watch for deviation that happens between joints, instead of at them.

Other than that, everyone's mentioned all the ways I know. You're not going to be able to tell pretty often. That's what hospitals are for.

 

[JCampbell]

Maybe I'm wrong but we were taught not to make a field diagnosis, that is the hospitals job. We are told that whether fracture or sprain: access PMS, splint according to protocols, access PMS again, and transport.

 

[RyanMidd]

As long as you're trying to differential Dx sprains/strains and dislocations, look up 'subluxation' as well. I've encountered two (told after the fact), but I treated both as dislocations. I.E. splint it where it is, and ask them if they'd like some Ento.

 

[Epi-do]

As someone who has broken multiple bones, and had more sprains/strains than I can count, you aren't always going to know what you are dealing with.

I had a broken arm, just above the wrist when I was a kid that had no swelling or pain for the first couple days. It wasn't until I put a substantial amount of stress on it that I had pain and swelling. The doc was able to see where it was beginning to heal on the x-ray.

On the flip side, I had one sprain in particular that everyone, including the docs, were amazed wasn't broken. It was much more painful than any of the breaks I have had.

Basically, if you suspect any sort of ortho-type injury, treat it appropriately. The only way to know for sure when it isn't obvious is to get some imaging done.

I'm going to take "warranted" as treatment that my protocol states a patient with a certain condition either should receive or is eligible to receive. So pain medication wouldn't be warranted in a patient with a bloody nose, but it would be with chest pain non-responsive to nitro/ASA/O2. Is that a fair interpretation of warranted or were you using it another way? (I don't mean that as snarky as it sounds, I'm asking seriously)

I can't remember verbatim what the pt said but I think refused is an accurate description in this case. I told him that as we got closer to the hospital the road was going to get rougher (it is REALLY bad near the hospital we were going to) and he was going to have to be moved when we got to the hospital and that pain medication could make things more comfortable for him. He said something like "I'm fine, I don't need anything, it really doesn't hurt at all anymore."

The RN at the ED was surprised that he hadn't had anything, and right after I got done giving report she turned to the pt and asked him if he would like any pain medication and he again stated that he didn't want anything and was ok.

Was the patient informed that it was part of your protocols and that his stating "no" would be considered a "refusal" rather than a decline of something that really should be optional unless you see there is a reason to justify altered mental status?

I have no issue with not giving pain medication but rather the terminology some in EMS use especially when the patient hasn't had a chance to read your protocols to know that they are "refusing" what you are directed to do.

The same holds true when someone when a suspected sprained ankle is advised by EMS they can go by POV rather than ambulance. Yet, the EMT(P)s have the patient sign a "refusal of care" form.

 

[mycrofft]

But the crux is immobilize approprtiately and go.

Refusal and refusal forms are tricky, a good form and training should guide you, a bad form and no training can put you and the pt in bantha dudu.

Plus, say the pt is refusing/declining a given aspect of tx but still requesting tranport. I've seen EMT's throw up their hands, but I've seen them explain to the pt that if measure abc isn't done the EMT would possibly cause more injury or pain, and the pt will go along on that basis.

A thread on refusals and refusal forms would seem appropriate. Where are our resident lawyers?

 

[Akulahawk]

Another thread swerved from the original question... Given that we're discussing the sprain/dislocation/fracture injuries, the majority of them will be limb/joint injuries. Discerning sprains, dislocations, and fractures is just not something that most field providers are ever taught. If you do know what to look for, know how to do the testing, and have experience doing those evaluations, then yes, you can discern pretty accurately whether or not your patient has a sprain, dislocation/subluxation, or a fracture.

As a Paramedic, will that knowledge change my field Tx? No. Paramedics aren't allowed to do anything other than treat as if it's a fracture. In another field that I have significant training in, it would, in fact, change the Tx plan.

 

[mycrofft]

To really get off thread..

Pragmatic basic prehospital EMS is supposed to be fairly simple, and we're going to dogpile a post once in a while (well, fairly frequently) because there are that many of us on here once in a while and (shhhh) it isn't rocket science.
I think folks should (and I do) report excremento like pinup pictures or uncivil responses, or send an IM to the poster.

And three is five and five is four.<_<

 

[Akulahawk]

The question still had not been answered... and I quote

Hello all,

I was just curious as to how you recognize a sprain vs. a break. To me, it's just hard to tell.

My answer is: Generally as a field provider, you won't have to. With proper training and education, it is possible to learn how to do it quite accurately. I do know how to do it. In my own personal experience, many Physicians do not know how to do this well. As a Paramedic, I can't do the testing necessary to confirm my evaluation. If I take that particular hat "off" (as in off-duty)... then yes, I can, and have, done precisely that.

But why would one consider pain management to be so "off track" on a thread involving breaks and dislocations? Just because some feel left out if their county or service does not allow for it does not mean it should be totally ignored and not discussed in fear of be scrutinized by someone who believes the laws of this forum are the Word. Even EMT-Bs can provide some pain relief to the patient.

 

[Aidey]

It wasn't turning into a discussion on pain management though, it was turning into a discussion on the semantics of the word "refusal". I ceased replying because of the fact that it was leading the thread off topic. Which this discussion is also doing.
