Summary
Sacral insufficiency fractures (SIFs) present nonspecific pain and are often missed. Minimally invasive sacroiliac fusion with trans-sacral screw fixation effectively treats unstable SIFs, reducing pain and improving function.
Area of Science:
- Orthopedics
- Radiology
- Geriatrics
Background:
- Sacral insufficiency fractures (SIFs) are underdiagnosed stress fractures in weakened bone, often presenting as low back or pelvic pain.
- Nonspecific symptoms and low sensitivity of conventional radiographs contribute to delayed diagnosis, frequently misdiagnosed as other conditions.
