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.
