-
A prospective study evaluating a cohort of patients with spondylotic cervical spine compression. ⋯ The DTI appears to be a promising imaging modality in patients with spondylotic spinal cord compression. It reflects the presence of symptomatic myelopathy and shows considerable potential for discriminating between symptomatic and asymptomatic patients.
-
Retrospective review of a prospectively maintained surgical database. ⋯ Thoracoscopic-assisted microsurgical resection is a safe, effective, and minimally invasive method of treating symptomatic HTDs in appropriately selected patients. The symptoms of most patients improve or resolve with minimal morbidity.
-
A retrospective study of 30 consecutive cases of pyogenic cervical spine infection, excluding postoperative infections. ⋯ Radical surgical debridement and appropriate antibiotic provide a reliable approach to achieve complete healing of the inflammation in cervical spondylodiscitis. Magnetic resonance imaging of the whole spine is recommended in all cases so as not to miss another infection in the spinal column. Regarding the surgical options, ventral plating after corpectomy for spondylodiscitis should be avoided.
-
An investigation of mechanical destabilization of the lumbar ovine intervertebral disc (IVD) inducing IVD degeneration (IVDD) as determined by multiparameter outcome measures (magnetic resonance imaging [MRI], IVD composition, biomechanical testing, gene profiling, immunohistochemistry, and immunoblotting). ⋯ Lumbar IVDD was reproducibly induced with a 6 × 20 mm(2) annular lesion, with focal dysregulation of MMP gene expression, cell cloning in the inner AF, loss of NP aggrecan, and disc height. Loss of aggrecan from the NP was not attributable to increased proteolysis in the interglobular domain by MMPs or ADAMTS.
