Cutaneous Anesthesia of the Lateral Femoral Cutaneous Nerve

• Status: Completed
• Trial end date: 2017-06-09
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to investigate and describe the anatomical differences in distribution of the blocked area following a perineural LFCN (Lateral Femoris Cutaneous Nerve) block with either 8 ml or 16 ml of Ropivacaine, in relation to incision lines used in THA (Total Hip Arthroplasty). Furthermore, we examine any loss of motor function in Musculus Quadriceps due to posible involvement of the Femoral Nerve. This trial will be conducted in healthy volunteers, as a blinded, randomized, paired trial.
