Ultrasound TFP (Transversalis Fascia Plane) for Analgesia After Iliac Crest Bone Graft Harvest

Iliac crest bone graft harvest is associated with acute pain that can lead to chronic postoperative pain. Local anesthetic infiltration and regional anesthesia could be of interest to reduce opioid consumption during and after surgery, reduce hyperalgesia and the associated risk of chronic postoperative pain. In this surgery, local anesthetic infiltration of the iliac crest is associated with a pain reduction compare with placebo. Some studies have shown the benefit of a TAP (transversus abdominal block) for postoperative analgesia after iliac crest bone graft harvest. The TFP block (transversalis fascia plane block) has been recently described. Considering the nerves trajectories, the TFP block is probably anatomically the most appropriate block for analgesia after iliac crest bone graft harvest. The aim of this study is therefore to assess the benefit of an ultrasound TFP block for analgesia after iliac crest bone graft harvest compare with local anesthetic infiltration Design is prospective, randomized, double blind, controlled study
