Intradisk Electrothermal Therapy / IDET
Using image intensifying technology a flexible catheter is placed in the anulus fibrosis
of the intervertebral disk. A minute coil at the tip of the catheter is then heated.
This leads to the denervation of so-called pain receptors in the anulus fibrosis as well
as other associated structures. The heat transforms the collagen of the anulus which
closes small tears found there.
Indications
- chronic lower back pain
- lack of improvement with non-invasive therapies
- pain must be reproducible during diskography
- no previous operations on the affected disk
Value
Treatment involving thermocoagulation of the anulus fibrosis is possible. The procedure is
only sensible when MRI images (magnetic resonance imaging) confirm mild degeneration of disks.
The procedure is not appropriate in treating nerve root irritation caused by protruding or
herniated disks.
Advantage
This is a minimal invasive procedure, available on an out-patient basis.
Follow-Up
A program of physical therapy stressing isometric muscle training should be initiate two
weeks after treatment. A corset should be worn for the first two weeks.
Work
Full function can be expected about two weeks after treatment. Heavy physical activity should
be avoided for three months. Heavy lifting must especially be avoided in order to allow the
ransformation of the anulus collagen to occur.
Sport
Care should be taken in choosing activities in order to minimize adverse effects on the healing process.
Results
The latest studies from America show definite improvement in 70% of cases studied.
