For bone fracture injuries, particularly femur fractures, the femoral nerve block (FNB) can provide a fast and effective means to control pain. However, this method is not always employed due to the fact that positioning the needle and therefore the block can be time consuming and challenging, and if not precisely placed, the nerve block results in poor pain control. Traditional methods for nerve blockade include the blind technique and use of a peripheral nerve stimulator (PNS). Unfortunately, neither of these methods provide a reliable guide for needle placement and can lead to intraneural placement and/or failed attempts.
