Pericapsular nerve group (PENG) block is a novel technique that provides analgesia in hip surgeries while preserving motor function. This study aimed to identify developmental differences and variations regarding PENG block sonoanatomy in the inguinal region in children.
A total of 150 children between 28 days and 18 years were included in this prospective, observational, descriptive study. The participants were divided into six groups according to growth and development periods. Ultrasonographic measurements representing block depth, needle length, and the vicinity of femoral nerve (FN) and femoral artery (FA) to the block area were collected.
Block depth: 16.2 ± 4.0 mm in infants (28 days-12 months); 33.5 ± 6.1 mm in adolescents (145-215 months). Needle length: 24.2 ± 5.9 mm in infants; 39.3 ± 6.6 mm in adolescents. The distance of FA to the block area: 4.4 ± 2.0 mm in infants; 11.6 ± 5.7 mm in adolescents. The distance of FN to the block area: 0.7 ± 0.8 mm in infants; 2.9 ± 4.0 mm in adolescents. FN-FA distance: 2.2 ± 1.4 mm in infants; 3.8 ± 1.8 mm in adolescents. In 49/150 (32.7%) cases the FN overlapped the perpendicular line between iliopsoas notch and skin. The lateral femoral cutaneous nerve (LFCN) was involved in the ultrasound frame in 11/50 (22%) children under the age of three.
Especially in children under three years of age, LFCN should be visualized during the pre-block preparation phase. The out-of-plane approach is not recommended in the PENG block due to the FN's alignment on the path of a vertical needle trace.

关节囊周围神经组（PENG）阻滞是一种在髋关节手术中提供镇痛同时保留运动功能的新技术。本研究旨在确定儿童腹股沟区PENG阻滞超声解剖结构的发育差异和变异。
本前瞻性、观察性、描述性研究共纳入150名年龄在28天至18岁之间的儿童。根据生长发育期将参与者分为六组。收集代表阻滞深度、针长度以及股神经（FN）和股动脉（FA）与阻滞区域距离的超声测量数据。
阻滞深度：婴儿（28天至12个月）为16.2±4.0毫米；青少年（145至215个月）为33.5±6.1毫米。针长度：婴儿为24.2±5.9毫米；青少年为39.3±6.6毫米。FA与阻滞区域的距离：婴儿为4.4±2.0毫米；青少年为11.6±5.7毫米。FN与阻滞区域的距离：婴儿为0.7±0.8毫米；青少年为2.9±4.0毫米。FN - FA距离：婴儿为2.2±1.4毫米；青少年为3.8±1.8毫米。在49/150（32.7%）例中，FN与髂腰肌切迹和皮肤之间的垂线重叠。在11/50（22%）名三岁以下儿童中，股外侧皮神经（LFCN）被纳入超声视野。
特别是在三岁以下儿童中，在阻滞前准备阶段应观察到LFCN。由于FN在垂直针迹路径上的排列，不建议在PENG阻滞中采用平面外进针方法。
