STUDY DESIGN This retrospective, questionnaire-based investigation evaluated iliac crest bone graft (ICBG) site morbidity in patients having undergone a single-level anterior cervical discectomy and fusion (ACDF) procedure performed by a single surgeon (T.J.A.). OBJECTIVE To evaluate acute and chronic problems associated with anterior ICBG donation,(More)
STUDY DESIGN Systematic review. OBJECTIVE To describe the various ways chronic low back pain (CLBP) is classified, to determine if the classification systems are reliable and to assess whether classification-specific interventions have been shown to be effective in treating CLBP. SUMMARY OF BACKGROUND DATA A classification system by which individual(More)
STUDY DESIGN Prospective cohort study. OBJECTIVE To precisely measure the effect of anterior cervical fusion on neck motion. SUMMARY OF BACKGROUND DATA Anterior cervical decompression and stabilization procedures are successful in treating recalcitrant cervical radiculopathy and cervical myelopathy. Most assume that these "fusion" procedures result in a(More)
STUDY DESIGN Retrospective radiographic review. OBJECTIVE To investigate the effects of cervical disc herniation on kinematics at adjacent vertebral motion segments. SUMMARY OF BACKGROUND DATA Kinetic magnetic resonance imaging (kMRI) is an alternative method to conventional MRI, which allows evaluation of the cervical spine in a more physiologic,(More)
STUDY DESIGN A prospective, multicenter, cross-sectional analysis of data from the National Spine Network database. OBJECTIVES To compare the relative impact of radicular and axial symptoms associated with disease of the cervical spine on general health as measured by the SF-36 Health Survey, and to compare the impact of these symptoms among patients of(More)
BACKGROUND Ischemic optic neuropathy resulting in visual loss is a rare but devastating complication of spine surgery. Elevated intraocular pressure (IOP) results in decreased perfusion and possibly ischemic optic neuropathy. We performed a randomized, prospective trial to evaluate the effect of head positioning on IOP during lumbar spine fusion. METHODS(More)
Vertebral injuries occur in a predictable and reproducible manner that is dependent upon the mechanism of injury. Each mechanism of injury leaves distinct imaging 'fingerprints' regardless of the location in the spine. This chapter will discuss four areas: the mechanisms of injury and their imaging 'fingerprints'; abnormalities of alignment and anatomy,(More)
Lumbar spinal stenosis, which affects an ever-increasing number of patients, is best defined as a collection of clinical symptoms that includes low back pain, bilateral lower extremity pain, paresthesias, and other neurologic deficits that occur concomitantly with anatomic narrowing of the neural pathway through the spine. The narrowing may be centrally(More)
BACKGROUND CONTEXT Traumatic cervical facet dislocation accounts for a disproportionate rate of neurologic disability. The relative importance of patient and management variables, including the timing of spinal reduction, in ultimate neurologic outcome has not been well defined. PURPOSE To analyze data from a cohort of patients sustaining traumatic(More)
BACKGROUND CONTEXT Cigarette smoking has a deleterious effect on spinal fusion. Although some studies have implied that nicotine is primarily responsible for poor fusion outcomes, other studies suggest that nicotine may actually stimulate bone growth. Hence, there may be a dose-dependent effect of nicotine on posterior spinal fusion outcomes. PURPOSE The(More)
