Objective: To determine by ultrasound (US) the spinal canal depth (SCD) in neonates and subsequently establish a nomogram and simple formula for calculating this distance.
Design: 116 US measurements were performed by two investigators in 105 neonates at the L3-L4 inter-vertebral space. Both anterior (ASCD) and posterior (PSCD) spinal canal depth were measured and mid-canal spinal depth (MSCD) calculated. Measurements of intra- and inter-observer variability were also performed.
Results: There is a clear relationship between body weight (W, kgs) and all SCD measurements in neonates. In particular, MSCD = 2.2W + 6.81mm, (R2 correlation coefficient 0.76), approximated by 2W + 7mm.
Conclusion: SCD measurements are easily determined by US in neonates, with good correlation between weight and MSCD.
