To estimate the safety window for needle insertion in the posterior approach to the tibialis posterior by ultrasonography, particularly in a clinical setting.
Cross-sectional study.
University hospital.
Healthy volunteers (108 legs, from 22 men and 32 women).
Not applicable.
Distance between the tibia and neurovascular bundles in the posterior aspect of the tibia on a transverse ultrasonographic scan.
The safety window at the midpoint was significantly larger than the upper third (0.62-2.16 cm, average 1.47 ± 0.38 cm vs 0.51-1.62 cm, average 1.16 ± 0.31 cm). The depth at the midpoint was significantly more shallow than the upper third (1.57-3.16 cm, average 2.31 ± 0.34 cm vs 1.76-3.66 cm, average 2.52 ± 0.38 cm). Body weight, height, tibial length, and leg circumference showed positive correlation with the safety window at both points.
The midpoint may be more favorable than the upper third for needle insertion to the tibialis posterior with a posterior approach.
通过超声评估经后入路进行比目鱼肌进针的安全窗口，特别是在临床环境下。
横断面研究。
大学医院。
健康志愿者（22 名男性和 32 名女性，共 108 条腿）。
无。
横断超声扫描时胫骨后神经血管束与胫骨之间的距离。
中点的安全窗口明显大于上三分之一（0.62-2.16cm，平均 1.47±0.38cm 比 0.51-1.62cm，平均 1.16±0.31cm）。中点的深度明显比上三分之一浅（1.57-3.16cm，平均 2.31±0.34cm 比 1.76-3.66cm，平均 2.52±0.38cm）。体重、身高、胫骨长度和小腿围与两点的安全窗口均呈正相关。
与后入路经上三分之一进针相比，中点可能更有利于比目鱼肌进针。
