The Sacral Multifidus Plane Block for Analgesia After Coccygectomy: Case Report

Coccygodynia results from traumatic, nontraumatic, or idiopathic causes. Chronic cases resistant to conservative treatments may necessitate surgery. This case report highlights the innovative use of sacral multifidus plane block (S-MPB) for multimodal pain management after a coccygectomy performed under spinal anesthesia. The patient, suffering from chronic coccygodynia due to exostosis, underwent surgical removal of the coccyx and associated fistula. S-MPB was chosen for its simplicity, efficacy, and safety, providing postoperative analgesia without complications. This approach suggests that S-MPB is a promising addition to the pain management arsenal for coccygectomy, warranting further investigation to optimize its application and outcomes.
