Tannoury T, et al. - A detailed retrospective chart review of patients who had undergone minimally invasive anterolateral retroperitoneal antepsoas lumbosacral fusion (MIS-ATP) approach for lumbar fusion between T12-S1 was done to investigate complications correlated with MIS-ATP. Nine hundred forty patients with a total of 2,429 interbody fusion levels done via MIS-ATP were recognized during the study period. During the perioperative period, 678 patients sustained one or more complications, of which 25.5% were surgical and 74.5% were medical. Overall, during a postoperative period of 1 year from the date of surgery, 78 surgical complications pertaining to the index procedure were recorded. No major vascular or direct visceral injuries were faced. Thus, the MIS-ATP approach gives safe access to anterolateral interbody fusions between T12-S1. The ATP approach is done by the spine surgeon, does not need neuromonitoring, and guarantees minimum to no psoas muscle retraction leading to significantly decreased postoperative thigh pain and rare neurologic injuries. Moreover, the direct and clear visualization of the retroperitoneal vasculature granted by the ATP approach decreases the risk of inadvertent vascular injury.
