STUDY DESIGN A retrospective review of prospectively collected data. PURPOSE To introduce the sternum-disk distance (SDD) method for approaching the exact surgical level without C-arm guidance during anterior cervical discectomy and fusion (ACDF) surgery and to evaluate its accuracy and reliability. OVERVIEW OF LITERATURE Although spine surgeons have tried to optimize methods for identifyin...

BACKGROUND AND PURPOSE Previous authors have described the locations of provoked responses to cervical diskography from C3-C4 to C6-C7, but we have found no description of the findings at C2-C3. This study was undertaken to analyze the sensations provoked during cervical diskography at C2-C3 and to compare the results with those provoked at C3-C4 and C4-C5. METHODS The locations of diskograph...

Study Design Retrospective cohort study. Objective The objective was to measure the change of flavum ligament diameter during positional changes of the cervical spine using kinetic magnetic resonance imaging (MRI) and to examine the correlational diameter changes of the flavum ligament, disk bulging, and the spinal canal from extension to flexion positions. Methods One hundred eight-nine patien...

Parvibaculum lavamentivorans DS-1(T) utilized the commercial surfactant linear alkylbenzenesulfonate (LAS) (20 congeners with C(10) to C(13) side chains) as a carbon and energy source by shortening the side chain, and sulfophenylcarboxylates (SPCs) and similar compounds (e.g., alpha,beta-unsaturated SPCs [SPC-2Hs]) were excreted with quantitative recovery of the sulfophenyl moiety. 2-(4-Sulfoph...

STUDY DESIGN An in vitro biomechanical investigation of the immediate stability in cervical reconstruction. OBJECTIVES The purpose of this study was to compare the segmental stability afforded by the interbody fusion cage, the anterior locking plate, and the "gold standard" autograft. SUMMARY OF BACKGROUND DATA Recently, interbody fusion cage devices have been developed and used for cervica...

Metabolomic studies of increased fat oxidation showed increase in circulating acylcarnitines C2, C8, C10, and C12 and decrease in C3, C4, and C5. We hypothesize that urinary F2-isoprostanes reflect intensity of fatty acid oxidation and are associated with circulating C2, C8, C10, and C12 directly and with C3, C4, and C5 inversely. Four urinary F2-isoprostane isomers and serum acylcarnitines are...
