Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Nielsen et al. reported that when iliopsoas plane block was performed on healthy volunteers, the injection solution in Hip MRI was confined to the myofascial compartment, which was known to include all sensory branches of the femoral nerve that control the hip joint. The maximal muscle strength of knee extension did not decrease before and after Iliopsoas plane block in Volunteer. Since there is no clinical study conducted on patients after the volunteer study, the investigators intend to evaluate the analgesic and motor preserving effects of the iliopsoas plane block in a group of patients undergoing total hip arthroplasty.
