Thoracic spondylosis, better termed 'degenerative thoracic spine disease', is rare and failure to recognize it is mainly due to its rarity and to the complexity of symptomatology which can lead to prolonged and continued morbidity. During the past 4 years, the authors have treated 28 patients with thoracic spine degeneration with varied clinical manifestations, ranging from local pain, radiculopathy to radiculomyelopathy. In six patients, myelopathy developed gradually, four showing features of pseudoclaudication. Two had an acute onset of myelopathy after minor trauma. Radiological examination, including CT scans in a few patients, demonstrated facetal hypertrophy, ossification of the ligamentum flavum and ossification of the posterior longitudinal ligament. One patient had posterior osteophytosis of thoracic spine at multiple level. Surgical decompression for localised stenosis yields good results, but the prognosis for those with diffuse or segmental stenosis is guarded.
胸椎骨质增生，更确切地称为“退行性胸椎疾病”，较为罕见，未能识别它主要是由于其罕见性以及症状学的复杂性，这可能导致长期和持续的发病。在过去4年中，作者治疗了28例有不同临床表现的胸椎退变患者，临床表现从局部疼痛、神经根病到神经根脊髓病不等。6例患者脊髓病逐渐发展，4例表现为假性间歇性跛行特征。2例在轻微创伤后急性发生脊髓病。包括少数患者的CT扫描在内的放射学检查显示小关节肥大、黄韧带骨化和后纵韧带骨化。1例患者在多个节段有胸椎后骨赘形成。针对局限性狭窄进行手术减压可取得良好效果，但对于弥漫性或节段性狭窄患者的预后则需谨慎评估。
