Efficacy of Adding Adductor Canal Block to Sciatic Nerve Block in Hallux Valgus Surgery

Background Optimal postoperative multimodal analgesia strategies were still under investigation in many orthopedic surgeries. The aims of this study were to determine the effects of adding the adductor canal block to the popliteal sciatic nerve block on sedation need, tourniquet pain, postoperative pain, and patient-surgeon satisfaction in patients operated for hallux valgus correction. Methods In this prospective, randomized, and controlled clinical trial, group S patients were performed only popliteal sciatic nerve block with 10 ml 0,5% bupivacaine and 10 ml 2% prilocaine in the prone position, group S + A were performed adductor canal block with 10 ml of 0,5% bupivacaine and 10 ml of 2% prilocaine with popliteal sciatic nerve block. Results Demographic data, duration of surgery, tourniquet time, surgeon satisfaction, complication rate, motor block time, time to first pain, first analgesic administration time and opioid consumption were similar between the two groups. Sensory and motor block onset time, tourniquet pain and additional sedation need rate were statistically significantly lower and patient satisfaction was significantly higher in Group S + A. Conclusion Adding the adductor canal block to the popliteal sciatic nerve block increases the quality of the peripheral nerve block and patient satisfaction with decreasing tourniquet pain and sedation need in hallux valgus correction surgery.
