Regional anaesthesia for orthopaedic surgery

Recently, there has been considerable interest in regional anaesthetic techniques, particularly in peripheral nerve blockade, for orthopaedic limb surgery. Many traditional nerve-block techniques have been significantly modified to improve their role in both in-patient and out-patient surgery. The introduction of long-acting local anaesthetic with a better safety profile as well as better equipment for continuous nerve blockade has further increased the use of such techniques in the provision of postoperative analgesia. The recent developments described in this review are likely to result in wider use of these techniques in years to come.
