胸椎椎間板症におけるTransthoracic approachとCostotransversectomy

Transthoracic Approach and Costotransversectomy in the Thoracic Discogenic Disease

I．はじめに

　胸椎の椎間板症（椎間板ヘルニアと脊椎症による骨棘形成を含む）は，頸椎や腰椎の場合と比べて比較的稀ではあるが，重篤な神経症状を起こす可能性があり，またその診断も容易でないことがある^2,3）．

　その臨床症状には特徴的な所見はなく，脊髄腫瘍，動静脈奇形，変性疾患などとの鑑別診断が必要となる^7）．

The thoracic discogenic disease is the rarest, yet is most devastating of all disc lesions.

The clinical manifestations including myelopathy and radiculopathy are not characteristic, therefore accurate rediological diagnosis has to be made by carefully performed myelography and CT. and re-cently by MRI.

Historically conventional laminectomy has been attended with terrible results such as paraplegia.
