The oblique prepsoas retroperitoneal approach to the lumbar spine for interbody fusion or oblique lumbar interbody fusion (OLIF) provides safe access to nearly all lumbar levels. A wide interval between the psoas and aorta allows for a safe and straightforward left-sided oblique approach to the discs above L5. Inclusion of L5-S1 in this approach, however, requires modifications in the technique to navigate the complex and variable vascular anatomy distal to the bifurcation of the great vessels. While different oblique approaches to L5-S1 have been described in the literature, to our knowledge, no previous study has provided guidance for the choice of technique. ⋯ Inclusion of L5-S1 in OLIF is safe and feasible through three different approaches but likely involves greater operative complexity. In our early experience, inclusion of L5-S1 showed no increase in early complications. This is the first series that reports the use of 3 different oblique approaches to L5-S1. The proposed "facet line" in the preoperative MRI may guide the choice of approach.

The role of telemedicine within the realm of spine surgery is evolving, catalyzed by the recent pandemic. Specifically, the capability of this technology to provide high-quality, cost-effective care without an in-person interaction and physical examination remains poorly defined. ⋯ Our findings suggest that telemedicine evaluations are efficient means of preoperative assessment of spine patients and delineation of surgical plans. These results may support innovations that can optimize access to care for patients.
