Use of Alexis® Retractor in Anterior Lumbar Interbody Fusion: First Experiences at a Single Center

Retroperitoneal approach for anterior lumbar spine fusion (ALIF) surgery is a widespread used in surgery. It normally requires the use of metallic retractors fixed to operative table. The friction between blades and soft tissues can produce injuries. In this study, we present initial experience ALIF surgeries performed with Alexis retractor, self-holding retractor made 2 stiff plastic rings joined by cylindrical reinforced polyurethane sheath that provides 360° circular retraction. We believe its could provide an excellent exposure allow atraumatic retraction mini-invasive ALIF. case series 11 patients who underwent using ring wound retractor. all cases, pararectal retroperitoneal was performed.
