Summary
This study presents a fluoroscopic-guided technique for precise cannula placement during sacral insufficiency fracture treatment. This method overcomes challenges posed by metal artifacts in CT scans, improving procedural accuracy.
Area of Science:
- Orthopedic surgery
- Interventional radiology
- Spinal imaging
Background:
- Sacral insufficiency fractures cause significant pain and can occur with osteoporosis.
- Percutaneous vertebroplasty is a treatment option for these fractures.
- Standard imaging guidance (fluoroscopy and CT) faces challenges with sacral fracture treatment, especially with prior spinal instrumentation.
Purpose of the Study:
- To describe a novel technique for accurate cannula placement in sacral insufficiency fractures.
- To address limitations of current imaging modalities in patients with spinal hardware.
Main Methods:
- A technique utilizing fluoroscopic imaging for cannula guidance is detailed.
- This method is applied to a patient with a sacral insufficiency fracture and prior pedicle screw fixation.
Main Results:
- The described fluoroscopic technique enables reliable cannula placement.
- It offers a viable alternative to combined fluoroscopic-CT guidance in challenging cases.
Conclusions:
- Fluoroscopic guidance provides a reliable method for cannula placement in sacral insufficiency fractures.
- This technique is particularly beneficial for patients with spinal hardware that causes CT artifact, enhancing treatment safety and efficacy.
