Open anterior approaches for lumbar spine procedures

Abstract With the advent of anterior lumbar interbody fusion (ALIF) and articifial discs as common procedures for the treatment many spinal problems such as pseudoarthrosis, degenerative disc disease and internal disc disruption from trauma, anterior exposure has become an increasingly popular procedure for the general, thoracic, urologic and vascular surgeon. Despite this, the body of literature describing this procedure is lacking. Dividing the approach for anterior spinal surgery into the thoracolumbar, mid-lumbar, and lumbosacral regions, we describe the basic techniques and anatomy needed to perform these open approaches, specifically, repairs of disc spaces T12–L2, L2–5, and L5–S1, respectively. The technique for the retroperitoneal approach will be discussed in detail; however, issues involved with indications for transperitoneal approach and technical “pearls” will also be discussed.
