Minimally Invasive Lumbar Fusion

Interest in minimally invasive surgery (MIS) of the spine is on the rise because of advertised advantages over standard open procedures as well as a perceived benefit in perioperative morbidity and patient recovery. This article reviews the current literature concerning MIS lumbar fusion and examines the evidence supporting these proposed advantages along with the limitations of these technically challenging techniques. From the available data, some perioperative advantages might be supported, although the evidence is not robust. In addition, concerns have been raised regarding the potential for increased complications as well as the lack of long-term results with MIS lumbar fusion.
