We measured the tibial dimensions and distances to anatomical landmarks at puncture sites A (proximal: 10\u00a0mm distal to the tibial tuberosity; distal: 10\u00a0mm proximal to the malleolus medialis) and B (chosen by palpation of the pediatrician), in 40 newborns in four weight groups (&lt;\u20091000\u00a0g; 1000\u20132000\u00a0g, 2000\u20133000\u00a0g, and 3000\u20134000\u00a0g). Sites were rejected if they fell short of the assumed safety distance to the tibial growth plate of 10\u00a0mm. If both A and B were rejected, puncture site C was determined sonographically at the maximum tibial diameter while maintaining the safety distance. Puncture site A violated the safety distance in 53% and 85% (proximally and distally, respectively) and puncture site B in 38% and 33%. In newborns weighing 3000\u20134000\u00a0g, at median (IQR), the most suitable puncture site at the proximal tibia was 13.0\u00a0mm (12.0\u201315.8) distal to the tuberosity and 6.0\u00a0mm (4.0\u20138.0) medial to the anterior rim of the tibia. The median (IQR) diameters at this site were 8.3\u00a0mm (7.9\u20139.1) (transverse) and 9.2\u00a0mm (8.9\u20139.8) (anterior\u2013posterior). The diameters increased significantly with increasing weight.<\/jats:p><jats:p><jats:italic>\u00a0 Conclusion:<\/jats:italic> This study adds concise, practical information on the implementation of IO access in neonatal patients: the tibial dimensions in newborns in four different weight groups and initial data on anatomical landmarks to easily locate the IO puncture site.
