This is a randomized, double-masked, placebo-controlled clinical trial. The results will not be available until the completion of enrollment and unmasking of treatment groups. Therefore, there are no resultsfindings to report at this juncture as we are still completing enrollment. The tasks of the no-cost extension Year 5 encompassed continued recruiting, enrollment and data collection 131 subjects enrolled to date for all centers 60 subjects provided crossover treatment Amputee support group outreach, prosthetics groups outreach, and clinic outreach conducted Data collection ongoing for all enrolled subjects We have but 13 subjects left to enroll to complete the study, and we would have enrolled these final subjects by the end of the no-cost extension Year 5 except the hurricane that hit Puerto Rico this last summer knocked out the factory that makes the local anesthetic used in this study-ropivacaine-and, so our enrollment was halted because ropivacaine cannot be purchased in the United States. It is unclear when the factory will begin producing ropivacaine again but, if it is not available by April 2018, we will consult with the Scientific Officer regarding the possibility of switching to a different long-acting local anesthetic-bupivacaine-for the final 13 subjects. The Department of Defense has approved a second no-cost extension year through December 24, 2018
