Liposome Bupivacaine for WRIST Blocks
Study Details
Study Description
Brief Summary
Treatment of Dupuytren's contracture requires multiple injections into the palm of the hand to weaken the cords, followed by rupture of the strands 2 days later. Anesthesia is required for both phases of treatment. It is hypothesized that extended-release liposome bupivacaine prolongs nerve blockade of the wrist allowing patients to undergo this 2-part regimen with less pain.
