Brief summary

The purpose of this study was to evaluate the analgesic efficacy of the nervus cutaneous femoral lateralis (NCFL) blockade on postoperative pain after total hip replacement surgery. The NCFL-block is a pure sensory block. We hypothesized that the NCFL-block would reduced the postoperative pain without delaying mobilization.
