The efficacy of anterior spine exposure by an orthopedic surgeon.

This retrospective study was designed to document the incidence and types of perioperative complications that occurred with anterior spinal fusion surgery performed solely by an orthopedic spine surgeon. This study is contrasted to previous studies that document complications from anterior approaches performed by an orthopedic surgeon with the assistance of a general or a vascular surgeon. Specifically, the procedures included thoracotomies, thoracolumbar retroperitoneal, and lumbosacral approaches. Our sample consisted of 450 patients who underwent anterior spinal fusion between levels T1 and S1, from 1985 to 1997. Patient and surgery characteristics included age, sex, diagnosis, levels of fusion, blood loss, operative time, hospitalization time, complications, American Society of Anesthesiologists state, assessment of risk factors, previous surgery, and surgical approach used. Average follow-up was 41.69 months, with a minimum of 12 months and a maximum of 132 months. Our results indicated that anterior procedures performed solely by our senior orthopedic surgeon had a lower incidence of complications, less blood loss, and shorter operative time than anterior procedures performed by an orthopedic surgeon and a vascular or a general surgeon. Our findings suggest that the anterior spinal exposure is a safe approach that may be performed solely by a spinal surgeon who is knowledgeable and experienced.
