Bober K, et al. - This randomized controlled trial was designed to distinguish whether a fascia iliaca block reduces postoperative pain and narcotic consumption and improves early functional outcomes in primary total hip arthroplasty (THA) conducted through the mini-posterior approach. A sum of 122 patients were included for the final analysis between September 2017 and September 2019. Applying a mini-posterior approach, eligible individuals received a primary THA with epidural anesthesia. Postoperatively, individuals were allocated randomly to receive a fascia iliaca compartment block or a placebo block. They noted numeric rating scale pain scores, narcotic consumption, and functional outcomes at regular intervals postoperatively. After mini-posterior THA, it was recorded that a fascia iliaca compartment block does not enhance functional performance and does not reduce pain levels or narcotic usage, but does raise the risk of quadriceps weakness postoperatively. Researchers do not considered routine fascia iliaca compartment blocks after THA conducted with the mini-posterior procedure.
