PURPOSE To measure the effect of extension, flexion, lateral bending, and axial rotation loads applied to the spine on the anatomic relationship of the spinal nerves in the neural foramen to the ligamentum flavum and the intervertebral disk, anc to determine the effect of disk degeneration on the response to loading. METHODS Cadaveric lumbar motion segments were examined with CT and MR imagin...

objectives: belonging to papaveraceae family, glaucium vitellinum is one of the persian endemic plants which has not been investigated biologically. the present paper focused on the assessment of the antibacterial and antifungal activities of the total methanol extract and alkaloid sub-fraction of the flowering aerial parts of g. vitellinum. materials and methods: the antibacterial and antifung...

BACKGROUND Previous studies have shown that if performed without radiographic guidance, the loss of resistance (LOR) technique can result in inaccurate needle placement in up to 30% of lumbar epidural blocks. To date, no study has shown the efficacy of measuring the depth of the posterior complex (ligamentum flavum, epidural space, and posterior dura) ultrasonographically to distinguish true an...

Calcification of Ligamentum Flavum (CLF) is an uncommon disorder. We present a 56-year-old patient with an acute inflammatory, febrile neck pain and higher value of ESR mimicking spine infection. The imaging investigations conclude for the diagnosis of calcification of the ligamentum flavum. Our observation illustrate the difficulties to differentiate, clinically, infection and calcium pyrophos...

PURPOSE A comparison of MRI and computed tomography-myelography (CTM) for lumbar intracanalar dimensions. To compare the capability and reproducibility of MRI and CTM in measuring the cross-sectional morphology of intracanalar lesions of the lumbar spine. MATERIALS AND METHODS MRI and CTM of lumbar disc levels from 61 subjects with various lumbar spinal diseases were studied. Dural area, dura...

BACKGROUND Hypertrophy of the ligamentum flavum is a pathological condition that causes neurological symptom (radiculopathy and / or myelopathy) and usually occurs in the thoracic,2 less frequently in the cervical spine that commonly involves thoracic spine. This study was conducted to analyse the clinical presentation and outcome of surgery of ossified ligamentum flavum at thoracic spine. ME...
