[Indications for epidural steroids in back pain and in radiculopathy].

Back pain is very frequent in western countries and it represents a very high social cost. The treatment is based on five modalities: medication, physiotherapy, invasive technics, rehabilitation programs and psycho-social approaches. Several treatments may be proposed simultaneously and introduced gradually. Steroid administration by epidural injection is frequently used in Belgium, even though no prospective randomised studies have shown a real benefit over the long term. The indications for epidural injection must be carefully chosen. These include subacute pain (less than six months) in the lower limbs despite a well observed medical treatment. Patients are invited to give informed consent; the technic must be performed in an appropriate environment by an experienced physician. The initial treatment of back pain is medical. This pathology is multifactorial and the relief of symptoms is often incomplete. The patient should be urged to feel responsible for and involved in his treatment.
