Background Open posterior spinal procedures involve extensive soft tissue disruption, increased hospital length of stay, and disfiguring scars. Our aim was to demonstrate the feasibility of using robotic‐assistance for minimally invasive exposure of the posterolateral spine with and without carbon dioxide (CO 2 ) insufflation. Methods Sheep specimens underwent minimally invasive subperiosteal dissection of the spine during three trials. The da Vinci S Surgical system was used for access with and without working space support via CO 2 insufflation. Results Without insufflation, a sub‐paraspinal muscle tunnel measuring 16 cm was developed between two 5 cm incisions. With insufflation, the one‐sided tunnel length was 12.5 cm but without the soft tissue trauma and obstructed visualization experienced without CO 2 . Conclusions The use of robot‐assistance for minimally invasive access to the posterior spine appears to be feasible. The use of CO 2 insufflation greatly improved our ability to visualize and access the posterior vertebral elements.
