L3-L4 location: Palpation method confirmed by US
An anesthesiologist will locate the L3-L4 space using the palpation method (Tuffier's line). An investigator trained in US imaging will proceed to the US exam of the spine specifically aiming to identify the L3-L4 intervertebral space. The investigator will note if the same level was identified and if not, which one was according to the US exam.
