Forty-two patients with developmental dysplasia of the hip (DDH) who were undergoing a periacetabular osteotomy (PAO) were randomized to receive a transversus abdominis plane (TAP) block (n=21) or a no blockade control (n=21). The primary outcome of interest of this study was opioid consumption. The secondary outcomes of interest included the following: pain at rest and during movement which was measured using a Numeric Rating Scale (NRS), quality of life evaluated using a self-reported Quality of Recovery (QoR-9) questionnaire, incidence of postoperative nausea and vomiting (PONV), operative time, and length of hospital stay. All outcomes were measured at 24 hours, 48 hours, and 6 days post-surgery. Results of this study have demonstrated that the primary outcome was statistically significantly reduced in the TAP block group compared to the control at 24 hours, 48 hours, and 6 days post-surgery (p=0.01; p=0.04; p<0.001, respectively). No statistical significant differences were observed for all other measures between the TAP block and control groups (p>0.05). NRS pain scores in the TAP block group was statistically significantly higher during motion vs rest (p=0.042). No complications were observed for either groups both during and after surgery.
