Abstract Abstract In Brief In Brief Favorites PDF Get Content & Permissions Go to Full Text of this Article In Brief: We established a human herniation model that reliably produced nucleus extrusion during cyclic loading. This is accomplished by choosing only specimens with low disc degeneration, which should be validated by radiographs and intradiscal pressure measurements. An exemplary test with the Barricaid implant showed that it seems to prevent the nucleus from reherniating. Go to Full Text of this Article Open

Abstract Abstract In Brief In Brief Favorites PDF Get Content & Permissions In Brief: Retrograde ejaculation (RE) is a specific sexual dysfunction and is a known potential complication of anterior lumbar spine surgery. The purpose of this study was to investigate the incidence of RE based on quantitative semen analysis and to compare the rate with that identified using a standardized questionnaire administered by telephone. Based on semen and urine analysis, the RE rate was found to be 9.8%, and was not greater in patients in whom BMP was the graft material used. The rate identified by a questionnaire was 41.7%, which was not supported by the quantitative analysis. Buy
