Clinical Trial Summary
In this prospective multi-centre double-blind trial the effect of the X-ray examinations
controlled periradicular therapy should be examined in (approximately 300) adult patients
with low back pain pain caused by foraminal stenosis radiculopathy or spinal stenosis.
A periradicular therapy (PRT) is a special radiological, low-risk therapy for chronic back
pain caused by wear and tear of the cervical, thoracic, and lumbar spine or a herniated disc
or disc bulge. Partially pain might also radiate to the hips or extremities and cause
radicular symptoms.
Description:
Controlled periradicular therapy (PRT) is a microinvasive interventional pain release
procedure. Advantage of targeted pain therapy is exact administration of effective drugs to
the nerve root in the area of the thoracic, lumbar or sacral spines. It is used like as
effective treatment in the patients with radicular pain caused by foraminal stenosis
radiculopathy or spinal stenosis.
Spinal stenosis is the narrowing of spaces in the spine which causes pressure on the spinal
cord and nerves. Discogenic radicular irritation syndrome is usually caused by protrusion of
intervertebral disc or prolapsed disc. The most common is lumbar and sacral radiculopathy
which could by exactly verified by CT or magnetic resonance imaging. The biggest profit with
the best response on this therapy has patients who are resistant for physiotherapy or per
oral medicament therapy.
Intervertebral space verification is provided by X-ray examination imaging. Than in this
place is Tuohy needle inserted. Position of Tuohy needle is verified by application of low
dose of contrast. When the right position of needle is secured than effective drugs are
administered: local anesthetic - Bupivacaine 0,25% (1-2ml) together with corticosteroid
injection -Depo-Medrol (40mg). PRT involves several medicable effects: anaesthetic - positive
effect on pain transmission in nerve fibers, antichemical - limitation of chemical products
from sequestered discs, Anti-edematous - reduction of root nerve oedema, antiphlogistic -
inhibition of phospholipase A2, antifibrotic - reduction of scar production.
Trial will compare groups of patients after fulfilment inclusion criteria's who will undergo
microinvasive interventional pain release procedure - PRT.
The first group of patients will undergo PRT procedure in the intervertebral space
responsible for skin dermatome were the pain is radiating.
Second group of patients will undergo double PRT procedure in the intervertebral space
responsible for skin dermatome where the pain is radiating and also in the intervertebral
space above where usually is disc lesion responsible for origin of pain localized. After
first visit in ambulance patients will be about study informed. After agreement patient will
be in to the study involved. Specific unique nine digits number will be assigned to each
patient. Then patients will be randomized in to groups by special evaluated software created
especially for this study. Patients will agree that about type of PRT (one level or two
levels) will be informed until the end of the study. This way will be patients blinded.
Second examination will be provided after 6 months. Patients will be in the beginning
introduced to doctor only by their unique number. Doctor will be blinded and he will not
dispose with information about microinvasive procedure and will examine patient. Data which
will be collected: (Visual analogue scale, pain radiating dermatome, global pain scale,
changes in analgesics drugs consumption). All acquired information will be noted in to the
special anonymous protocol. Also patients will anonymously fulfill Oswestry Low Back
Disability Questionnaire. The third examination will be provided after 12 months same way.
Patients will be in the beginning introduced to doctor only by their unique number. Doctor
will be blinded and he will not dispose with information about microinvasive procedure and
will examine patient. Data which will be collected: (Visual analogue scale, dermatome where
pain is radiating, global pain scale, changes in analgesics drugs consumption). All acquired
information will be noted in to the special anonymous protocol. Also patients will
anonymously fulfill Oswestry Low Back Disability Questionnaire (ODI). If the patient will
need to a see a doctor in the reason of deterioration of pain feeling and if the ODI will not
increase more than 10% against patient's origin ODI value than one PRT is allowed in the
spinal space responding to a pain radiating dermatome during first six months after patients
inclusion to trial. Under the same conditions another PRT is allowed during next six months.
When ODI will increase more than 10% against patient's origin ODI value and more than 1 PRT
during six month interval will be needed, than patient will be excluded from the study.
