Experimental disc injections in subjects with no history of low back symptoms. ⋯ If strict criteria are applied, the rate of false-positive discography may be low in subjects with normal psychometric profiles and without chronic pain. Significantly painful injections were very common in subjects with annular disruption and chronic pain or abnormal psychometric testing.

Efficacy and validity of radiofrequency neurotomy for chronic lumbar zygapophysial joint pain.
A prospective audit. ⋯ Lumbar medial branch neurotomy is an effective means of reducing pain in patients carefully selected on the basis of controlled diagnostic blocks. Adequate coagulation of the target nerves can be achieved by carefully placing the electrode in correct position as judged radiologically. Electrical stimulation before lesioning is superfluous in assuring correct placement of the electrode.

Case Reports[Sacral osteoid osteoma--a rare cause of back pain in childhood and adolescence].
Osteoid-osteoma should be included in the differential diagnosis of any young patient with pain in the back. The tumor is the most common cause of painful scoliosis in adolescents. In spite of typical symptoms the diagnosis is often delayed. ⋯ Scintigraphy and computed tomography can establish the diagnosis. Therapeutic procedures are medical treatment, operative excision or percutaneous radiofrequency coagulation. We report the case of a thirteen year old boy who suffered from an osteoid-osteoma in the sacrum.

Percutaeous radiofrequency facet rhizotomy--experience with 118 procdedures and reappraisal of its value.
There have been many reports of percutaneous radiofrequency facet rhizotomy, perhaps better referred to as facet denervation, usually performed under general anaesthesia, with inconsistent success rates. ⋯ Percutaneous radiofrequency facet denervation is simple and safe, still worth considering in patients with disabling spinal pain that fails to respond to conservative treatment. The use of general anaesthesia shortens the operating time and the patient's discomfort without impairing success rate.
