The Sacroplasty Procedure And Instrumentation In Lateral View

Description

Viewed in strict lateral profile, the animation tracks a sacroplasty cannula from posterior to anterior as it advances through the dorsal sacral cortex into the sacral ala and body, with the L5 vertebral body and L5 to S1 disc space serving as superior reference points. The sacral promontory, anterior sacral cortex, and posterior elements form depth cues as the trajectory is adjusted to remain intraosseous. Stepwise motion highlights the instrument tip position relative to the sacral foramina and presumed course of the sacral nerve roots. Depth matters. Sacroplasty is performed most often for painful sacral insufficiency fractures in osteoporotic patients or after pelvic radiotherapy, where early stabilization can reduce micromotion and improve weight bearing tolerance. The animated sequence clarifies what a static plate cannot: the continuous relationship between cannula angulation, depth, and cement delivery, including how a small change in trajectory can place the tip closer to a neural foramen or the anterior cortex. Cement injection is shown as a controlled fill within cancellous bone rather than a diffuse spread, reinforcing why careful incremental injection and surveillance for extravasation are central to safe technique. Use this clip in interventional radiology and spine surgery teaching files to orient trainees to lateral fluoroscopic landmarks, or in a procedural atlas explaining cannula placement and cement injection mechanics for sacral stabilization. It also fits CME modules on management of sacral insufficiency fractures and complications such as cement leakage toward the foramina or presacral soft tissues.
