Involvement of Transverso-sacral- Neo- Articulations or of Transverso-iliac Articulations in Chronic Lumbago

• Status: Terminated
• Trial end date: 2015-02-01
• Target enrollment: 0
• Participant gender: All

Summary

The specific aim of this study is to determine whether, when treated with corticoid infiltration, certain chronic lumbagos could be explained by the presence of a neo-articulation.The primary criteria is to determine the difference between the mean pain during the latest 24 hours preceding the infiltration and the mean pain preceding the visit S4 (visit 4 weeks after the infiltration)

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Nantes University Hospital
• Treatments: Anesthetics; Lidocaine; Pharmaceutical Solutions
