Inter-semispinal Fascial Plane Block (ISPB) Versus Erector Spinae Plane Block (ESPB) in Posterior Cervical Spine Surgery

Recent advances in regional anesthesia techniques have aimed to provide more targeted and effective pain relief. Among these, the erector spinae plane (ESPB) block, the multifidus cervicis plane (MCP) block, and the paraspinal interfascial plane block (PIP) is rapidly expanding in cervical spine surgery. Of these, the inter-semispinal fascial plane block (ISPB) has gained popularity as an analgesic technique for posterior cervical spine surgery also, (ESPB) have been tried successfully for posterior cervical spine surgery in few recent trials. But to our knowledge, no study compared the efficacy of both blocks. So, the current study aimed to compare the analgesic efficacy of inter-semispinal fascial plane block versus erector spinae plane block in patients undergoing elective posterior cervical spine surgery.
