Is this trial a fit for you?

Likely a good fit

Ideal candidates include skeletally mature patients aged 21 and older with impending or actual non-displaced pelvic fractures due to metastatic malignancy or geriatric patients aged 65 and older with pelvic fragility fractures.

Probably not a fit

Patients who are uncooperative, incapable of following directions, prisoners, or deemed surgically unfit will not benefit from this study.

What this trial studies

This project evaluates the effectiveness of the IlluminOss pelvic implants in patients suffering from pelvic metastatic disease, focusing on those with pain and risk of pathologic fractures. The study aims to confirm significant reductions in pain and improvements in function for patients with non-displaced or minimally displaced fractures, as well as geriatric patients with pelvic fragility fractures. By utilizing prophylactic fixation, the study seeks to minimize symptoms and enhance quality of life for this vulnerable population. The research will analyze clinical and radiographic features to better predict fracture risk and the need for intervention.

Why it matters

Potential benefit: If successful, this approach could significantly reduce pain and improve mobility for patients with pelvic fractures due to metastatic cancer.

How similar studies have gone: Previous studies have shown success with prophylactic fixation in long bones, but this approach in the pelvis is less established and may offer novel insights.
