Back pain sends more Brooklyn residents to the doctor than almost any other condition. For patients who do not respond to conservative treatment, fluoroscopy-guided epidural injections are one option doctors may discuss, and understanding how they work helps patients make an informed decision. The full picture of how that guidance works is set out in a guide to fluoroscopic-guided injections.
What fluoroscopy-guided injections are
Fluoroscopy is a type of real-time X-ray imaging that allows a physician to guide a needle precisely to the affected area of the spine before delivering medication. The imaging is meant to improve accuracy compared to injections done without guidance.
How they may help with back pain
These injections are typically used to help reduce inflammation around an irritated spinal nerve, which may provide temporary relief from pain that radiates into the back, hip, or leg. Relief duration varies significantly from patient to patient.
What the procedure involves
The procedure is done in a clinical setting, typically takes under an hour, and most patients go home the same day. Some soreness at the injection site is common in the days that follow.
Understanding the limitations
Epidural injections are not a permanent fix for the underlying cause of back pain, and relief is often temporary. They are one tool among several, and many patients pursue them alongside other treatment such as physical therapy or drug-free options like shockwave and laser therapy.
Talking to a specialist about your options
Because every patient’s spine and pain pattern are different, a proper evaluation is the best way to determine whether fluoroscopy-guided injections, a drug-free approach, or a combination of both makes sense for your situation.
Frequently asked questions
How much radiation is involved in a fluoroscopy-guided injection?
The imaging is used in short bursts to check needle position rather than run continuously, so exposure for a single injection is low. It is still a reason the procedure is avoided in pregnancy and a reason repeat procedures are spaced out. Anyone who has had several imaging studies recently can ask how exposure is kept to a minimum.
How many epidural injections can be given in a year?
There is no single rule, but repeat steroid injections are usually spaced by weeks rather than days and limited over a twelve-month period, and plans often set their own limits as well. The judgment rests on how much relief an earlier injection gave and for how long. Little or no benefit from two attempts usually prompts a change of plan rather than a third.
Do blood thinners have to be stopped before the procedure?
Often, and the timing depends on the specific medication. Because the needle passes close to the spinal canal, bleeding risk is taken seriously, and instructions differ between aspirin, clopidogrel, warfarin and the newer direct oral anticoagulants. The decision belongs with the prescribing physician, since stopping some of these carries its own risk. Nothing should be stopped without that instruction.
Can a steroid injection raise blood sugar in someone with diabetes?
Yes, it commonly does for a short period after the injection, sometimes lasting several days. People who monitor their glucose are usually advised to check more often during that window and to have a plan for higher readings. It is not normally a reason to avoid the injection, but it is a reason to mention diabetes beforehand.
Back pain that keeps coming back?
An evaluation looks at what maintains the problem, not just what triggered it. More on lower back pain.
