Abstract
The article describes the anatomical relationships of peripheral nerves with theirs surrounding structures in the leg bellow knee joint. Attention is focused on the connective tissues that accompany macroscopically visible nerves.
Ultrasound imaging allows to identify superficial, deep fascias and fascial compartments of the leg. Visualization of superficial and deep structures enables the performance of nerve blockages at sites outside of usual locations.
Ultrasound assistance provides us with a wider range of peripheral nerve block options on the lower limb and allows to individually adjust the range of the blocks to patient's requirement.
