Retrospective Evaluation of Effect of Anterior Iliac Block

Retrospective Evaluation of Postoperative Analgesia Efficacy of the Anterior Iliac Block in Anterior Iliac Crest Bone Graft Harvesting: Preliminary Study

In this study, the investigators aimed to evaluate the effect of ultrasound-guided anterior iliac block which was performed preoperatively. Anterior iliac bone harvesting is associated with severe postoperative pain. As several fascial plane blocks were defined to provide analgesia, their effects are debatable and requires high volumes of local anesthetic considering the regional anesthesia technique used for the main surgical procedure.

Detailed Description

Autologous bone grafting is the method called the gold standard in the reconstruction of bone defects and nonunions. Anterior iliac crest is most frequently preferred as the source of autologous bone graft. However, severe pain after anterior iliac crest graft harvesting increases morbidity. Various regional anesthesia techniques have been defined for the purpose of postoperative analgesia. The mechanism of fascial plane blocks, one of these techniques, has not been fully elucidated and drug distribution varies from person to person. Postoperative analgesia of the iliac crest donor site can be achieved by i infiltration of local anesthetics or morphine. Single injection or continuous infusions of local anesthetic have proven effective in adults.

In this study; the investigators aimed to retrospectively scan the records of patients who received anterior iliac bone graft in our clinic and determine the postoperative analgesia effectiveness of anterior iliac block. The data obtained after the research will make a significant contribution to the literature in the postoperative analgesia management of patients who are planned to receive anterior iliac bone graft.
