Spinal microsurgery at the thoracic to sacral level in the "prone-oblique" position

Until the present time, almost all posterior approaches to the thoracic to sacral region have been made in either the knee-elbow or the prone position. Those positions, however, have potential disadvantages such as respiratory suppression and/or disturbance of venous return due to compression of the anterior chest and belly. In order to avoid the above mentioned disadvantages, the patient was laid on the operating table in a "Prone-Oblique" position, with the body rotating about 40 degrees around the long axis. The authors performed, with successful results, spinal operations via the posterior route in the "Prone-Oblique" position in 30 cases. An illustrative case was presented of a metastatic intramedullary tumor at the T11/12 level from an unresectable mammary cancer. The cancer had infiltrated and bulged out of the left anterior chest wall so severely and extensively that an operation in the conventional position was impossible. The metastatic tumor was totally and successfully removed via the posterior approach in the "Prone-Oblique" position without any complications related to the position. This "Prone-Oblique" position seems to be physiologically suitable, giving rise to no harmful compression of any part of the patient's body and it provides the surgeon a comfortable posture and a good operative view during microsurgery.

Harvey Cushing: first guest at "The Divine Banquet of the Brayne"

Harvey Cushing will remain forever ensconced in surgical memory as the visionary who established contemporary neurosurgery. Raised in Cleveland in a middle-class family with a medical background, he gave little indication early of his later prowess. A college education at Yale University yielded a modest performance, although he showed somewhat better promise as a medical student at Harvard University. During his surgical training at the Johns Hopkins Medical School, he emerged as a bright, industrious young man with a glint of steel to his intellect. From Halsted he learned the academic basis of surgery and the meticulousness necessary for technical success. Osler became his friend and provided him with a foundation in the history of medicine and the recognition of its importance in shaping the future. The decision to spend a year in Europe visiting clinics and renowned surgeons may have laid the foundations for the subsequent configuration of his career. In Britain he saw firsthand the glorious museums and libraries of the Hunters and the legacy that their schools of surgery had endowed to the nation. In Paris and London he mixed with the surgical aristocracy of the times and learned the power of societies and the traditions of their patrons. In Berne he was exposed to the surgical purity and physiologic expertise of Kocher, supported by the estimable scientific practice of Kroneker. As an "arbeid," Kocher posed him the problem of establishing the mechanism of the regulation of cerebral perfusion. This question, which he so rapidly and successfully unraveled, probably played a large part in igniting his enthusiasm toward the study of the brain as a future career. In his travels he encountered diverse intellects and experienced a wide panoply of European medical thought. He conversed widely at both a social and professional level and integrated all information into meticulously kept diaries that served as not only a record but also a template from which later plans were derived. A final 6-week sojourn in Liverpool working on the primate cortex with Sherrington, the greatest neurophysiologist of that time, may have sealed his decision to turn his initial project with Kocher into the opus of a lifetime. The 14-month tour of Europe transformed Cushing from a relative unsophisticate into a figure of giant proportions. All that he experienced became part of his life and was integrated into his subsequent career.(ABSTRACT TRUNCATED AT 400 WORDS)
