Brief Summary

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.

Conditions

Total Hip Arthroplasty

Outcome Measures

Primary Outcomes (1)

• Numeric rating scale pain score at rest

  Pain intensity at rest will be evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) 1, 6, 24, and 48 hours after the surgery.

  up to 48 hours after the surgery

Secondary Outcomes (2)

• Numeric rating scale pain score at movement

  up to 48 hours postoperatively

• Postoperative opioid consumption

  postoperative 24, 48hours
