Continuous Lumbar Plexus Block for Postoperative Pain Control After Total Hip Arthroplasty

Study Overview
=================
Brief Summary
-----------------
Continuous lumbar plexus and femoral blocks have been demonstrated to provide effective postoperative analgesia of the lower extremity following total joint arthroplasty. The purpose of this study was to compare these two techniques when used with intravenous patient-controlled analgesia and the use of patient-controlled analgesia alone for postoperative pain management following unilateral total hip arthroplasty.
