[0:00] We're going to do a one level eye mask case clinically. The patient is symptomatic for L5-S1 with a combination of an L5 radiculopathy, particularly exacerbated by vertical load and hyperextension.
[0:18] This phase of the case is the preoperative planning.
[0:21] I get a through the pedicle shot of L5 parallel to the end plate superior L5. Do the same thing at S1 and get the angle of attack there. We'll make a mark S1 left, a mark S1 right.
[0:37] And that'll be our entry point. We'll now adjust AP flora for a superior end plate view of L5. There's L5 left.
[0:46] We'll go to the Other side. There's L5, right.
[0:49] That gives us our pedicle map and it's going to give me complete exposure from pedicle L5 to pedicle S1.
