Summary
Femoroacetabular impingement is a pathologic process within the hip joint that results from a
mechanical discord between the femoral head and neck and the acetabulum that results in
chronic hip pain, hip labral tears and early progression of osteoarthritis of the hip.1, 2
Historically an open surgical hip dislocation was performed to treat patients with this
condition, however with recent advances in arthroscopy, patients more commonly now undergo
arthroscopic hip surgery. From a pain management standpoint, previous attempts to provide
peri-operative analgesia included intraarticular or portal analgesic injections. More
recently, regional anesthesia techniques are being employed to provide more reliable and
longer lasting post-operative pain control.3, 4 Currently, there are several local
anesthetics available for regional anesthesia. However, they only provide an average of 12-18
hours of post-operative pain control following a single injection.5 Bupivacaine is a local
anesthetic that has been used for many years by multiple routes to control post-operative
pain. A new formulation of the medication prolongs the release of the active ingredient after
a single injection and has been shown to result in up to 72 hours of post-operative
analgesia.6, 7 To the investigator's knowledge, there has not been any studies in the
literature comparing a historical control local anesthetic to this new formulation of
liposomal bupivacaine via a fascial iliaca regional soft tissue infiltration blockade to
provide post operative pain control following hip arthroscopy.
