Ultrasound assisted Simplicity III probe placement for SIJ radiofrequency denervation – case report and description of a novel technique

摘要: Introduction:  Sacroiliac joint (SIJ) dysfunction accounts for about 20% of patients with low back pain and is often overlooked. Following thorough assessment two diagnostic blocks, radiofrequency (RF) denervation the SIJ done as part multidisciplinary management. RF technically challenging incomplete due to complex variable innervation joint. Simplicity III probe one alternate methods denervating sacroiliac by creating a strip lesion lateral dorsal sacral foramina. Case Report: We successfully used novel technique combined ultrasound fluoroscopy imaging denervate patient after positive blocks. The procedure was carried out jointly an expert in guided procedures chronic intervention. Both found usage complimentary, reliable easy follow. outcome has been satisfactory describing 60% relief, increase daily activity, reduced analgesic consumption 12 weeks following Discussion: Conventional placement frequent projection changes are required. Pattern recognition characteristic structures seen image helped place probe. advantages double source visualisation many. It eases avoiding need thereby reducing time needed do this procedure. For same reason it also reduces exposure ionising radiation.
