The objective of the submitted work was to draw attention to some problems associated with the diagnosis and treatment of prolapse of sequestra of thoracic intervertebral discs. The investigated group comprised 9 subjects (4 women, 5 men) aged 33 to 67 years operated upon at the Neurosurgical Clinic in Kosice between Jan. 1 1982 and June 30 2001 on account of compression of nervous structures in the thoracic portion of the spine by sequestra of intervertebral discs. This was manifested by back pain, a sensation of stiffening of the muscles of the lower extremities, altered sensitivity and in all by impaired gait. Only one female patient developed urinary retention, another one painless paraparesis of the lower extremities, therefore the condition was evaluated as a demyelinisation process. In three patients as the only imaging examination method perimyelography was used, in another two it was supplemented by CT. Four patients were examined by MRI. This graphic method proved to be the most suitable. In all subjects of the investigated group the clinical picture and examination methods indicated a unilateral predominance of the affection. In five subjects it proved possible to remove the sequestream of the intervertebral disc via laminectomy, in another four a transpedicular approach into the spinal canal was used successfully. In all patients the condition improved after surgery.
