Sonographic imaging of the sciatic nerve and its division in the popliteal fossa in children.
BACKGROUND
High resolution ultrasound is a possible option for anesthetists to detect nerves. We tested the possibility of imaging the sciatic nerve and its division into the tibial and peroneal part using high resolution ultrasound in children.


METHODS
Twelve children up to 45 kg body weight were randomly selected. Using a handheld ultrasound system with a 10 MHz linear array probe the popliteal fossa and the back of the thigh were examined and measured. The sciatic nerve and its division were depicted by ultrasound.


RESULTS
The sciatic nerve and its division could be displayed in all children. The position of the nerve division showed large anatomical variation.


CONCLUSIONS
Ultrasound opens a window to detect the anatomy of the sciatic nerve in children. In addition, the surrounding anatomical structures can also be depicted. The results suggest a possibility of safe placement of a cannula for blockade of the sciatic nerve under visual control.
