NCT01385449
First received: June 28, 2011
Last updated: August 6, 2014
Last verified: December 2013
  Purpose

The primary hypothesis is that those patients who choose an interscalene catheter will have less pain postoperatively than those with single injection blocks. Secondary hypotheses examine physical therapy outcomes and incidence of parasthesia or pain following surgery for up to 3 months.
