Unanticipated transient sciatic nerve deficits from intra-wound liposomal bupivacaine injection during total hip arthroplasty.

ABSTRACT: Liposomal bupivacaine (Exparel®) is a novel formulation of local anesthetic used to provide extended postoperative analgesia as part of a multimodal pain control regimen in patients undergoing total joint arthroplasty. In the three total hip arthroplasty cases described, all patients exhibited a transient loss of neurologic function in the sciatic nerve distribution of the operated extremity lasting between 24 and 72 h during the immediate postoperative period. Due to the nature and duration of the deficits, it was concluded that they likely occurred as a result of unintended injection of the medication in close proximity to the sciatic nerve. To the best of our knowledge, these events have yet to be reported in the current literature. We recommend orthopaedic surgeons pay special attention during infiltration of the medication at the surgical site to avoid postoperative neurological deficits.
