Biochemical Alterations in Herniated Intervertebral Disks

Herniated intervertebral lumbar disc in the teenager.

Laminectomy compared with laparoscopic diskectomy and outpatient laparoscopic diskectomy for herniated L5-S1 intervertebral disks.

The objective of this study was to evaluate the clinical efficacy and cost effectiveness of inpatient and outpatient laparoscopic lumbar diskectomy (LLD) compared with laminectomy (LAM) in the surgical treatment of disabling L5-S1 disk herniation. Sixty-two adults underwent surgery for herniated L5-S1 intervertebral disks (31 LLD and 31 LAM). Operative blood loss (EBL) (milliliters), operative ...

Utility of high-dose contrast enhancement for detecting recurrent herniated intervertebral disks.

PURPOSE To study the utility of high-dose contrast enhancement in the detection of recurrent herniated disk fragments. METHODS Recurrent herniated disks were modeled in nine dogs by placing a fragment of normal autologous disk tissue in the epidural space at laminectomy. MR was performed at 30, 60, and 90 days with 0.3 mmol/kg of gadoteridol and repeated 24 hours later with 0.1 mmol/kg of gad...

Herniated intervertebral disc mimicking intraspinal tumor

Lumbar disc herniation is a relatively common disease. Magnetic resonance imaging (MRI) is the firstused diagnostic tool for evaluating spinal pathologies and represents adiagnostic gold standard. However, the diagnosis of intervertebral disc herniation can still be very difficult in some cases, even in this MRI era. Considering that little is known about this area, and to share our experience,...

Asymptomatic calcified herniated thoracic disks: CT recognition.

Among 270 CT scans of the thorax obtained over a 7-month period, four patients (1.5%) with calcified herniated thoracic disks were identified. Each of these patients presented with abnormal chest radiographs and had a CT examination for evaluation of suspected malignancy. None showed any signs or symptoms of thoracic spinal cord compression. The clinical significance of incidental thoracic disk...
