201 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 13: Injection therapies, low-back pain, and lumbar fusionThe medical literature continues to fail to support the use of lumbar epidural injections for long-term relief of chronic back pain without radiculopathy. There is limited support for the use of lumbar epidural injections for short-term relief in selected patients with chronic back pain. Lumbar intr...2014-01-01
202 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 14: Brace therapy as an adjunct to or substitute for lumbar fusionThe utilization of orthotic devices for lumbar degenerative disease has been justified from both a prognostic and therapeutic perspective. As a prognostic tool, bracing is applied prior to surgery to determine if immobilization of the spine leads to symptomatic relief and thus justify the performanc...2014-01-01
203 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 17: Bone growth stimulators as an adjunct for lumbar fusionThe relationship between the formation of a solid arthrodesis and electrical and electromagnetic energy is well established; most of the information on the topic, however, pertains to the healing of long bone fractures. The use of both invasive and noninvasive means to supply this energy and supplem...2014-01-01
204 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 11: Interbody techniques for lumbar fusionInterbody fusion techniques have been promoted as an adjunct to lumbar fusion procedures in an effort to enhance fusion rates and potentially improve clinical outcome. The medical evidence continues to suggest that interbody techniques are associated with higher fusion rates compared with posterolat...2014-01-01
205 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 12: Pedicle screw fixation as an adjunct to posterolateral fusionThe utilization of pedicle screw fixation as an adjunct to posterolateral lumbar fusion (PLF) has become routine, but demonstration of a definitive benefit remains problematic. The medical evidence indicates that the addition of pedicle screw fixation to PLF increases fusion rates when assessed with...2014-01-01
206 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 10: Lumbar fusion for stenosis without spondylolisthesisLumbar stenosis is one of the more common radiographic manifestations of the aging process, leading to narrowing of the spinal canal and foramen. When stenosis is clinically relevant, patients often describe activity-related low-back or lower-extremity pain, known as neurogenic claudication. For tho...2014-01-01
207 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine.

208 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 15: Electrophysiological monitoring and lumbar fusionIntraoperative monitoring (IOM) is commonly used during lumbar fusion surgery for the prevention of nerve root injury. Justification for its use stems from the belief that IOM can prevent nerve root injury during the placement of pedicle screws. A thorough literature review was conducted to determin...2014-01-01

210 Couldwell, William T.History and evolution of transsphenoidal surgeryInitial attempts at transcranial approaches to the pituitary gland in the late 1800s and early 1900s resulted in a mortality rate that was generally considered prohibitive. Schloffer suggested the use of a transsphenoidal route as a safer, alternative approach to the sella turcica. He reported the f...Neurosurgical history; Transsphenoidal surgery; Pituitary tumor2001
211 Couldwell, William T.False-negative magnetic resonance angiography with extracranial internal carotid artery stenosis: a report of two cases and review of the literatureMagnetic resonance angiography (MRA) is increasingly used as a noninvasive means to assess internal carotid artery (ICA) stenosis. When used alone, however, MRA may not be sufficiently accurate in certain settings to determine whether ICA disease meets surgical criteria. Although MRA has been recogn...Internal carotid artery stenosis; Magnetic resonance angiography2005
212 Couldwell, William T.; House, Paul A.; Salzman, Karen L.; Osborne, Anne G.; MacDonald, Joel D.; Jensen, Randy L.Surgical considerations regarding giant dilations of the perivascular spacesObject. Dilations of brain perivascular spaces (PVSs), also known as Virchow-Robin spaces, are routinely identified on magnetic resonance imaging studies of the brain and recognized as benign normal variants. Giant dilations occur only rarely and can be easily misdiagnosed as central nervous system ...2004
213 Couldwell, William T.Diagnosis and management of Cushing diseaseThe management of a case involving Cushing disease, defined as excess secretion of adrenocorticotropic hormone (ACTH) from a pituitary adenoma, remains one of the most vexing problems facing the pituitary surgeon. The systemic consequences of this endocrinopathy are profound morbidity and premature...2007-01-01
214 Kestle, John R. W.Sporadic osteochondroma of the cervical spineOsteochondroma is the most common benign tumor of bone, but axial skeleton involvement is uncommon and usually indicates a hereditary cause such as osteochondromatosis (hereditary multiple exostosis). 1 Approximately 7% of hereditary osteochondromas occur along the vertebral column, which is double...2006
215 Schmidt, Meic H.Thoracoscopic spine surgery for decompression and stabilization of the anterolateral thoracolumbar spineThe anterior thoracolumbar spine can be exposed via a variety of approaches. Historically, open anterolateral or posterolateral approaches have been used to gain access to the anterior thoracolumbar spinal column. Although the exposure is excellent, open approaches are associated with significant pa...Endoscopic spinal surgery; Thoracic spine; Lumbar spine; Thoracoscopic spinal instrumentation2005
216 Couldwell, William T.Inhibition of cellular growth and induction of apoptosis in pituitary adenoma cell lines by the protein kinase C inhibitor hypericin: potential therapeutic applicationProtein kinase C (PKC) is an enzyme involved in the regulation of cellular growth, proliferation, and differentiation in a number of tissues including the anterior pituitary, in which it is also believed to play a role in hormone secretion. Protein kinase C activity and expression have been found to...Apoptosis; Hypericin; Pituitary adenoma; Protein kinase C1996
217 Dailey, Andrew T.Guidelines for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 9: fusion in patients with stenosis and spondylolisthesisGuidelines. The performance of a lumbar PLF is recommended for patients with lumbar stenosis and associated degenerative spondylolisthesis who require decompression.
