Ultrasound guided sciatic nerve block is a very accurate and precise minimally invasive treatment. The treatment involves locating the sciatic nerve under ultrasound guidance and then performing a precise block of the nerve. The procedure can be performed quickly, precisely and with excellent results. This type of treatment is mainly used in cases of very severe sciatica or when anesthesia is required in the area of the sciatic nerve. The advantages of this type of treatment include fewer side effects, fewer complications, and longer block times. In the absence of such techniques, the path of the sciatic nerve was often confirmed through surface projection of the sciatic nerve, together with relevant auxiliary examinations, and then the block was performed based on the surgeon’s personal experience. However, with this technology, it is now possible to operate more accurately and quickly.
