This systematic review examined the efficacy of perioperative nerve blocks for pain control after hip arthroscopy.

The databases Embase, PubMed, and Medline were searched on June 2, 2015, for English-language studies that reported on the use of perioperative nerve blocks for hip arthroscopy. The studies were systematically screened and data abstracted in duplicate.

Nine eligible studies were included in this review (2 case reports, 2 case series, 3 non-randomized comparative studies, and 2 randomized controlled trials). In total, 534 patients (534 hips), with a mean age of 37.2 years, who underwent hip arthroscopy procedures were administered nerve blocks for pain management. Specifically, femoral (2 studies), fascia iliaca (2 studies), lumbar plexus (3 studies), and L1 and L2 paravertebral (2 studies) nerve blocks were used. All studies reported acceptable pain scores after the use of nerve blocks, and 4 studies showed significantly lower postoperative pain scores acutely with the use of nerve blocks over general anesthesia alone. The use of nerve blocks also resulted in a decrease in opioid consumption in 4 studies and provided a higher level of patient satisfaction in 2 studies. No serious acute complications were reported in any study, and long-term complications from lumbar plexus blocks, such as local anesthetic system toxicity (0.9%) and long-term neuropathy (2.8%), were low in incidence.

The use of perioperative nerve blocks provides effective pain management after hip arthroscopy and may be more effective in decreasing acute postoperative pain and supplemental opioid consumption than other analgesic techniques.
