ARTHROPLASTY
Examining the efficacy of a lateral femoral cutaneous nerve block after hip arthroplasty
Acta Anaesthesiol Scand. 2016 Oct;60(9):1297-30560 patients with moderate-to-severe pain during hip flexion immediately after total hip arthroplasty were randomized to be administered a lateral femoral cutaneous nerve block or saline. Patients were assessed for pain over 45 minutes after administration. Patients then underwent crossed-over to the other treatment.

Additionally, nonresponse to block was high among all patients.
