Background:

Sacral insufficiency fractures are a common cause of low back pain.
Current sacroplasty techniques involve short axis needle placement.
Polymethyl methacrylate is a commonly used bone cement for sacroplasty.

Purpose of the Study:

To describe a novel technique for sacroplasty using long axis needle placement.
To evaluate the ease of performance and cement distribution of this new approach.

Main Methods:

Percutaneous injection of polymethyl methacrylate into sacral insufficiency fractures.
Needle placement along the long axis of the sacrum, contrasting with previous short axis techniques.

Main Results:

The long axis approach is simpler to execute compared to the short axis method.
Improved distribution of polymethyl methacrylate cement along the sacral ala was observed.

Conclusions:

Long axis needle placement represents a more straightforward and effective technique for sacroplasty.
This technique enhances cement distribution, potentially improving treatment outcomes for sacral insufficiency fractures.
