STUDY DESIGN An anatomic, osteologic study of spina bifida occulta (SBO). OBJECTIVE To determine the prevalence and patterns of SBO in a large population and examine its relationship to age, sex, and race; then to evaluate SBOs relationship to the sacral table angle (STA) when compared with an age-matched control group. SUMMARY OF BACKGROUND DATA SBO(More)
The acute administration of morphine, alcohol or dopamine results in a pronounced suppression of the convulsions produced by alcohol in mice. The suppressive action of morphine on alcohol withdrawal in the mouse apparently is not a product of morphine intoxication, but rather to some other specific interaction between alcohol and morphine in the central(More)
Total joint arthroplasty and deformity surgery of the spine can require complex reconstructive procedures accompanied by the potential for major blood loss. In an attempt to minimize the perioperative blood loss associated with these procedures, recent focus has concentrated on the efficacy of pharmacologic agents. Antifibrinolytics such as(More)
STUDY DESIGN An anatomic, epidemiologic study of cervical endplate and facet arthrosis in cadaveric spines. OBJECTIVE To determine the prevalence of cervical endplate and facet arthrosis and the relationship between these 2 entities in a large population sample. SUMMARY OF BACKGROUND DATA Cervical endplate and facet arthrosis are common radiographic(More)
STUDY DESIGN Retrospective review. OBJECTIVE To quantify and describe perioperative complication rates in a large series of well-matched elderly patients who underwent lumbar decompression and arthrodesis. SUMMARY OF BACKGROUND DATA Posterior lumbar decompression and fusion is frequently performed to treat lumbar stenosis with instability. An increasing(More)
BACKGROUND Smoking is associated with reduced fusion rates after anterior cervical decompression and arthrodesis procedures. Posterior cervical arthrodesis procedures are believed to have a higher fusion rate than anterior procedures. QUESTIONS/PURPOSES We asked whether smoking (1) would reduce the fusion rate in posterior cervical procedures; and (2) be(More)
An ethanol-inhalation technique was used to determine a potential relationship between dopamine and central nervous effects produced by alcohol. Bothl-DOPA and intracranially injected dopamine resulted in attenuation of ethanol-induced withdrawal convulsion scores, whereas, haloperidol, a known dopaminergic blocker was found to significantly increase(More)
It is believed lumbar degeneration begins in the disc, where desiccation and collapse lead to instability and compensatory facet arthrosis. We explored the contrary contention that facet degeneration precedes disc degeneration by examining 647 skeletal lumbar spines. Using facet osteophytosis as a measure of facet degeneration and vertebral rim(More)
STUDY DESIGN An anatomic, epidemiologic study of facet arthrosis in cadaveric lumbar spines. OBJECTIVE To define the prevalence of lumbar facet arthrosis in a large population sample and to examine its association with age, sex, and race. SUMMARY OF BACKGROUND DATA Arthrosis of lumbar facet joints is a common radiographic finding and has been linked to(More)
Based on the data presented here and the clinical observations cited it would appear that although haloperidol has been used with a certain degree of success for the treatment of acute alcohol abstinence the authors would like to caution the clinician against widespread use of heloperidol for treatment of alcohol withdrawal. In experimentally induced(More)
