Lower limb nerve blocks

Lower limb blocks are increasingly used for analgesia for lower limb arthroplasties, either as single-shot or continuous technique. They allow excellent analgesia, encouraging early mobilization, and may reduce hospital stay. Fascia iliacus block for preoperative analgesia for neck of femur, and parasacral sciatic blocks for postamputation pain are two of the newer blocks described in this article. With the increased use of pure regional techniques for foot surgery with either popliteal or ankle blocks, it is an interesting time for lower limb regional anaesthesia.
