BACKGROUND Spinal cord stimulators are most often placed through a percutaneous approach using minimal sedation and local anesthesia to facilitate intraoperative testing. However, when leads need to be placed using a laminectomy incision additional anesthesia is required which can complicate intraoperative testing. There is no consensus as to the best anesthetic choice when laminectomy-placed l...

Study Design Biomechanical study. Objective Posterior instrumentation is used to stabilize the spine after a lumbar laminectomy. However, the effects on the adjacent segmental stability are unknown. Therefore, we studied the range of motion (ROM) and stiffness of treated lumbar spinal segments and cranial segments after a laminectomy and after posterior instrumentation in flexion and extension ...

Lumbar intraspinal synovial cysts are included in the difference diagnosis of lumbar radiculopathy. Developing imaging modalities has result in increased reporting about these lesions. However, the case of bilateral new lumbar intraspinal synovial cysts after laminectomy has been rarely reported. We report of a rare case with bilateral lumbar intraspinal synovial cysts after laminectomy, requir...

PURPOSE The purpose of this study was to investigate the effects of unilateral pedicle screw fixation on the fusion segment and the superior adjacent segment after one segment lumbar fusion using validated finite element models. MATERIALS AND METHODS Four L3-4 fusion models were simulated according to the extent of decompression and the method of pedicle screws fixation in L3-4 lumbar fusion....

conclusions lumbar discectomy improves both the physical and mental health subscale of the quality of life in patients with chronic disc herniation. results physical and mental health scores of patients significantly improved after 6 and 12 months of lumbar discectomy. the mean improvement in physical health scores was significantly higher in female patients than in male patients. however, the ...

Background: Chondroitin sulfate proteoglycans (CSPGs) are the major cause of axonal regeneration failure at the site of lesion in spinal cord injury (SCI). Inflammation is believed to stimulate the upregulation of CSPGs expression. Recent evidence showed that trehalose reduces the development of inflammation in SCI. The aim of this study was to investigate the effect of trehalo...
