Use of Ultrasound in Lower Extremity Blocks.
Nerve "freezing" injections of the leg are very useful in providing anesthesia and pain relief for knee and ankle surgery. However, current nerve "freezing" techniques are "blind". As a result, they are not always successful and may cause complications, albeit infrequent.
The objective of the current study is to determine any advantage in performing these "freezing" injections under direct ultrasound guidance, to "visualize" the nerves. We feel that by developing this technique, it will allow us to perform these procedures with greater success and fewer complications.
