OBJECTIVE: To investigate the ultrasonographic anatomy of the lower leg for safe
and accurate needle placement into the tibialis posterior using the anterior
approach. DESIGN: Cross-sectional study. SETTING: University rehabilitation
hospital. PARTICIPANTS: Healthy volunteers (N=62; 30 men, 32 women).
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: 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. RESULTS: 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.
CONCLUSIONS: 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.
