Many patients present to the Emergency Department for low back pain. Determining whether these patients have a red-flag diagnosis can be difficult. Red flag diagnoses include
Cauda equina syndrome/ spinal cord compression
Almost all patients presenting with back pain, whether it be a muscle spasm or a spinal epidural abscess, will have back tenderness to some extent. So, how can you better differentiate benign from dangerous etiologies?
Trick of the trade: Spine percussion Percussion is an easy physical exam technique that can be used to risk-stratify patients that you suspect may have serious back pathology. Classically, percussion of the thoracic and lumbar spine should trigger pain in patients with serious back pain pathology, such as vertebral malignancy or a spinal infection. Because bone conducts vibration extremely well, percussion irritates deep space pathology. In contrast, percussion should not exacerbate discogenic pain, back strain, or muscular spasm.
Technique Position your finger over the spinous process, and percuss using your other hand. Repeat this for each vertebral level. With significant focal spine tenderness to percussion, the clinician should be more suspicious for worrisome pathology.
Just for the heck of it, I've looked up CES at Wellsphere.
There's not a lot about it.
Here's a red flag for doctors --- if a patient complains of bladder problems and back pains it isn't a good idea to send a patient home from the ER with a plastic urinal. That happened to me.
I even got booted out when I couldn't lie in a MRI machine. I was told to go home (in a different country) and get an MRI there. On my last visit, I got the MRI after complaining that I was lying in urine. Got air-evaced home and had surgery at the same time as this famous hospital would have done it.
My only regret with going home for surgery was that it made my suing the famous hospital a no-go.
