Effect of Nervus Cutaneous Femoris Lateralis-Blockade on Moderate Pain Responders After Total Hip Arthroplasty
The patients will be included the 1. or 2. day after surgery. All THA patients will be screened. Those reporting VAS > 40 during active 30 degrees hip flexion will be asked to participate.
Included patients will receive 2xNCFL (singleshot) first placebo (8 ml saline) and then ropivacaine (8 ml ropivacaine 7,5mg/ml) or the other way around (randomized). There will be 45 minutes between the two blockades. The blockades will be ultrasound guided.
