Figures & Tables

Fig. 1.

Short-axis ultrasound images of the right popliteal fossa. A. Gray-scale image demonstrating the typical topographic relationship between the sciatic nerve and adjacent vascular structures. B. Power Doppler image at the same level, facilitating differentiation of the artery and vein and confirming the position of the nerve relative to the vessels. N – nerve; A – artery; V – vein

Fig. 2.

Short-axis ultrasound image at the level of the sciatic nerve bifurcation, demonstrating division into the tibial nerve and the common peroneal nerve. The solid white arrow indicates the tibial nerve, and the dashed white arrow indicates the common peroneal nerve

Fig. 3.

Short-axis ultrasound image at the level of the lateral femoral condyle. The white star marks the common peroneal nerve, and the black asterisk marks the crural fascia. SF – subcutaneous fat; FC – femoral condyle; LGC – lateral head of the gastrocnemius muscle

Fig. 4.

Short-axis ultrasound image at the level of the fibular head. The white star marks the common peroneal nerve. LGC – lateral head of the gastrocnemius muscle; FH – fibular head; SL – soleus muscle; SF – subcutaneous fat

Fig. 5.

Short-axis ultrasound image at the level of the fibular neck. The white star marks the common peroneal nerve. LGC – lateral head of the gastrocnemius muscle; FN – fibular neck; SL – soleus muscle; SF – subcutaneous fat

Fig. 6.

Short-axis ultrasound image at the entrance of the peroneal tunnel. The white star marks the common peroneal nerve. PL – peroneus longus muscle; ED – extensor digitorum muscle; TA – tibialis anterior muscle; F – fibula

Fig. 7.

Short-axis ultrasound image at the distal peroneal tunnel. The white arrowhead indicates the superficial peroneal nerve, the white arrow indicates the deep peroneal nerve, and the plus sign (+) marks the tibial artery. PL – peroneus longus muscle; ED – extensor digitorum muscle; TA – tibialis anterior muscle
