　View Summary

<p>We studied degenerative changes in the cervical intervertebral discs of 497 asymptomatic subjects by MRI and evaluated disc degeneration by loss of signal intensity, posterior and anterior disc protrusion, narrowing of the disc space and foraminal stenosis. In each subject, five disc levels from C2-C3 to C6-C7 were evaluated. The frequency of all degenerative findings increased linearly with age. Disc degeneration was the most common observation, being present in 17% of discs of men and 12% of those of women in their twenties, and 86% and 89% of discs of both men and women over 60 years of age. We found significant differences in frequency between genders for posterior disc protrusion and foraminal stenosis. The former, with demonstrable compression of the spinal cord, was observed in 7.6% of subjects, mostly over 50 years of age. Our results should be taken into account when interpreting the MRI findings in patients with symptomatic disorders of the cervical spine.</p>

　View Summary

<p>Anterior decompression and fusion via an extrapleural approach was performed for 33 patients with myelopathy arising from thoracic disc herniation and the clinical usefulness and problems related to this procedure were assessed on the basis of surgical results and complications. The severity of the myelopathy was evaluated by the Japanese Orthopaedic Association score, and the surgical results were based on the recovery rate. The upper-level limit of decompression and fusion via the extrapleural approach was T4-5. The recovery rate for the mean postoperative follow-up period of 41 months was 66.7%. An age of 60 years or more, long duration of illness and severe preoperative myelopathy were indicators of a poor prognosis. Two patients suffered from a postoperative transient pulmonary complication due to hemothorax. X-ray examinations revealed good bone union in all the patients. The present study indicates that anterior decompression and fusion via the extrapleural approach is a useful technique which can be used to achieve a high success rate in the surgical treatment of thoracic disc herniation, if intervention is early.</p>
