Spine
-
Retrospective study of a prospectively assembled cohort. ⋯ Survival from subsequent spine operation was similar to adolescent idiopathic scoliosis series studied in the same manner. Life survival decline began at 4 years postoperative and was significantly associated with the occurrence of one or more perioperative complications. Even after successful spine deformity surgery, this population's health status is often precarious.
-
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.
-
Epidemiological study using national administrative data. ⋯ Frequency, utilization, and hospital charges of spinal fusion have increased at a higher rate than other notable inpatient procedures, as seen in this study from 1998 to 2008. In addition, patient demographics and hospital characteristics changed significantly; in particular, whereas the average age for spinal fusion increased, the in-hospital mortality rate decreased.

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.
