Ultrasound image of one specimen with measurement of TFA (tibia-fascia angle). Ultrasound image of TFA measurement (male cadaver, right leg) at a generated pressure level of 40 mmHg. For TFA measurement one line (solid line) was set on the anterolateral cortex of the tibia and the other line (dotted line) was set as a tangent to the curving anterior compartment fascia with its origin at the tibial attachment. TFA was the angle between the two lines (in this case 77.5°)
