To investigate the ultrasonographic anatomy of the lower leg for safe and accurate needle placement into the tibialis posterior using the anterior approach.
Cross-sectional study.
University rehabilitation hospital.
Healthy volunteers (N=62; 30 men, 32 women).
Not applicable.
The safety window (the tibia to the neurovascular bundle) and the depth to the midpoint of the safety window (skin to the tibialis posterior) at the upper third and the midpoint of the tibia were measured with a transverse ultrasonographic scan.
The safety window at the upper third of the tibia was significantly larger than that at the midpoint (P<.01). The safety window ranged from .64 cm to 2.13 cm at the upper third tibialis point and from .32 cm to 1.30 cm at the midpoint. The depth to the tibialis posterior at the upper third of the tibia was significantly deeper than that in the midpoint (P<.01). The depth ranged from 2.47 cm to 4.66 cm at the upper third tibias point and from 2.35 cm to 4.28 cm at the midpoint.
Ultrasonography is a useful tool in measuring the safety window and the depth to the tibialis posterior using the anterior approach. Considering the safety window, we suggest the needle placement at the upper third point of tibia rather than that at the midpoint.
通过前入路，研究小腿的超声解剖结构，以安全、准确地将针插入比目鱼肌。
横断面研究。
大学康复医院。
健康志愿者（N=62；30 名男性，32 名女性）。
不适用。
在上三分之一和胫骨中点处，用横断超声扫描测量安全窗口（胫骨到神经血管束）和安全窗口中点到（皮肤到比目鱼肌）的深度。
胫骨上三分之一的安全窗口明显大于中点（P<.01）。安全窗口范围在上三分之一胫骨点为.64cm 至 2.13cm，在中点为.32cm 至 1.30cm。胫骨上三分之一处的比目鱼肌深度明显大于中点（P<.01）。深度范围在上三分之一胫骨点为 2.47cm 至 4.66cm，在中点为 2.35cm 至 4.28cm。
超声检查是一种有用的工具，可用于测量前入路的安全窗口和比目鱼肌的深度。考虑到安全窗口，我们建议将针放置在上三分之一的胫骨处，而不是在中点。
