Ultrasound technique for determining the safe needle depth during lumbar puncture in young infants
Measurements performed on patients in the UALP group.
(A) The conus medullaris at the T12–L2 spinal level is identified.
(B) The probe is advanced caudally, and a measurement of the maximum safe depth is taken from the skin to the anterior border of the dural sac at the L3–4 interspace.
(C) The maximum safe depth is marked on a spinal needle with a caliper.
