Clinical Manifestation of Thoracic Spinal Canal Stenosis Caused by Ossification of the Ligamentum Flavum

Objective To summarize the diagnosis and treatment of thoracic spinal canal stenosis caused by ossification of the ligamentum flavum (OLF) and discuss its ralated pathogenic factors Methods Thirty five cases of thoracic spinal canal stenosis caused by OLF undergone surgical treatment from 1978 to 1997 were studied, there were 21 males and 14 females,with the average age of 51 years 85 7% of the lesion was between T10-L 1 intervertebral disc space 91 4% of the patients were heavy physical labors, 45 7% had obvious predisposing causes and 20% had history of spinal osteopathy or fracture The symptoms were various while the locating signs were definite 42 9% of the cases had pyramidal signs, and 20% had one or two positive signs Extensive degenerative changes were shown both in lesional and the nonlesional sites on iconography Results Thirty one cases were followed up for 1-18 years, with an average of 5 years and 7 months According to the criterion, of 12 cases in early stage treated with traditional vertebral laminectomy, 5 had excellent results, 2 had good results, 3 had no change and the other 2 were poor Of 19 cases in advanced stage treated with en bloc hemi articular process laminectomy, 15 were excellent, 4 were good and none was poor or without change Conclusion 1)OLF has a very close relation with the degenerative changes,and cause the symptoms of thoracic spinal cord compression very colorful and complications 2)En bloc hemi articular process laminectomy is an effective surgical approach for the treatment of thoracic spinal canal stenosis
