Quadratus lumborum block (QLB) is a facial plane block defined to provide analgesia from T7-L3 dermatomes. There are articles reporting that it is an effective analgesic method in hip surgeries. Suprainguinal fascia iliaca block (SIFIB) also blocks components of the lumbar plexus and provides effective analgesia in hip surgeries. The investigators aim to compare the effectiveness of QLB and SIFIB in patients undergoing primary total hip arthroplasty (THA).
