Summary
This study was designed to assess whether the injection of local anesthetic into the nerve
(intraneural), as opposed to around it (perineural), requires a shorter time to develop
surgical anesthesia of the lower leg.
The investigators will compare the two types of injection using the same drug, so as to
determine if there is an actual difference onset time. They will also examine the overall
success rate of either kind of sciatic nerve blocks as the sole anesthetic for non-emergent
orthopedic surgery.
The safety of these procedures will be examined by in-hospital and phone-call follow-up
contacts.
