Five years' experience of the retroperitoneal lumbar and thoracolumbar surgery

Retroperitoneal videoscopic spine surgery has been developed in our department since 1994. It has been used not only at the lumbar, but also at the thoracolumbar and lumbosacral level. Thirty-eight patients have been operated on. We have performed 12 thoracolumbar approaches, 23 lumbar approaches, and 3 retroperitoneal lumbosacral approaches. In every case, a video-assisted technique has been employed. These techniques have been used for anterior grafting in 18 cases of fracture, for corporectomy and grafting with or without anterior osteosynthesis in 6 cases of malunion, for cage implantation or isolated grafting in 10 cases of degenerative disc disease, and for the treatment of 4 cases of spondylodiscitis. Results were satisfactory for every type of pathology. The complications related to the approach were the same as those seen with open surgery; however, the videoscopic approach seems to us less invasive, with cosmetic benefit, less blood loss, and more rapid recovery. A video-assisted technique appears to be a good compromise between videoscopic technique and open surgery. With the development of these techniques, few indications remain for open anterior surgery on the lumbar spine in our opinion.
