Anterior Cutaneous Nerve Entrapment syndrome: A Case Report

Abstract

Anterior cutaneous nerve entrapment syndrome (ACNES) is a usually misdiagnosed and untreated or undertreated chronic state of pain. This syndrome is described by the cutaneous branches of the lower thoracoabdominal intercostal nerves become trapped at the lateral border of the rectus abdominis muscle, causing intense, frequently refractory, and persistent pain. The management strategies for ACNES include trigger point injections (diagnostic and therapeutic), ultrasound-guided blocks, and surgical neurectomy, in combination with systemic medication, as well as some newer technique such as radiofrequency ablation.
