PRT for herniated discs and nerve root pain
Periradicular therapy (PRT) is a targeted treatment around a nerve root. It may be considered, for example, for nerve root pain caused by a herniated disc.
Understanding your health
A picture helps explain the body.
These schematic 3D illustrations show affected structures and possible areas of discomfort. Similar symptoms may have different causes; the images do not replace a medical examination.
Targeted treatment at the nerve root
During PRT, medication is delivered close to the affected nerve root. The aim is to reduce local irritation and the associated pain.
The illustration explains the target region and is not a guide to performing the procedure.
When may PRT be considered?
Treatment may be considered for selected spinal conditions involving nerve root irritation, for example a herniated disc. We assess whether it suits your symptoms based on examination and available findings.
Individual planning
Before treatment, we discuss the procedure, possible risks and alternatives. PRT forms part of a treatment plan tailored to your circumstances.
Lumbar PRT: when pain travels down the leg
A herniated disc in the lumbar spine may irritate a nerve root. Pain can then radiate from the back or buttock into the leg. PRT specifically targets the affected nerve root; it is not a general treatment for every type of back pain.
What can a PRT injection achieve?
Local anaesthetic and, where appropriate, anti-inflammatory medication may relieve pain. The effect may be temporary. The injection does not remove the herniated disc and does not guarantee that surgery can be avoided.
Planning your treatment in Illingen
Please bring any existing MRI images, medical reports and a list of your medication. We compare your symptoms with the examination and imaging findings. The precise procedure, suitable medication and necessary observation afterwards are discussed with you in advance.
Tell us about blood thinners, allergies, diabetes, infections and any possible pregnancy. Do not stop medication on your own. Before the appointment, we clarify whether someone needs to accompany you and when you may drive again.
Risks and alternatives
Possible risks include bleeding, infection, reactions to medication and nerve injury. Exercise therapy and other forms of pain management remain important alternatives or additions, depending on the findings. Increasing neurological deficits may require a different treatment.
When to seek immediate medical help
New paralysis, bladder or bowel dysfunction, or numbness around the groin require immediate medical assessment. Do not wait for a routine PRT appointment; contact an emergency department, or call 112 for acute severe symptoms.
Frequently asked questions about PRT
Is PRT an injection into the disc?
No. The target is the area around the affected nerve root, not the inside of the disc.
How many treatments are needed?
This depends on your response. A fixed number cannot reasonably be promised before examination.
Does PRT also help pain that does not radiate?
That depends on the cause. Pain arising from the small spinal joints calls for other treatment approaches. We distinguish between nerve root pain and facet joint pain.
Will my health insurance cover the cost?
Please discuss the requirements and possible cost coverage with us and your insurer before starting treatment.
