Application of Preoperative Ultrasonography in the Percutaneous Minimally Invasive Repair of Acute Closed Achilles Tendon Rupture

Figure 2

(a) The anatomical structure was located preoperatively by body surface localization and ultrasonography. The blue arrow shows the course of the small saphenous vein and sural nerve drawn through the body surface markers. The yellow arrow shows the exact course of small saphenous vein and sural nerve located by ultrasonography. The orange arrow represents the midline of the Achilles tendon measured by ultrasonography. The red arrow shows the medial edge of the Achilles tendon on ultrasonography. The green arrow shows the lateral edge of the Achilles tendon on ultrasonography. The white arrow shows the broken end of the Achilles tendon on ultrasonography. (b) Ultrasonography image of ruptured Achilles tendon in sagittal view. The yellow arrow shows proximal Achilles tendon stump. The white arrow shows distal Achilles tendon stump. The purple arrow shows hematoma.
