A popliteal block is a regional anesthesia technique used in procedural medicine to numb the lower leg and foot. Ultrasound guidance is crucial for this procedure, enabling precise visualization of the sciatic nerve and its divisions (tibial and common peroneal nerves) in the popliteal fossa. This real-time imaging ensures accurate needle placement and optimal local anesthetic spread, minimizing complications and improving block success rates for surgeries below the knee.
Ultrasound-guided popliteal blocks enhance patient safety and comfort during foot and ankle surgeries. The visual feedback from the ultrasound transducer allows clinicians to avoid vascular structures and achieve effective pain management, reducing the need for general anesthesia. This technique is a cornerstone in modern regional anesthesia, widely applied in orthopedic and podiatric procedures for effective pain control.
