Background:
Pelvic metastatic bone disease (MBD) leads to significant pain and functional impairment. Managing these lesions through an open approach involves invasive procedures linked to potential morbidity and complications. The IlluminOss system, a UV light-activated polymer implant, has shown efficacy and safety in managing various fractures. This study evaluates the effectiveness of IlluminOss photodynamic bone stabilization system (PBSS) in pelvic MBD.
Methods:
A retrospective cohort review was conducted, including all patients treated with the PBSS system for MBD of the pelvis and acetabulum.
Results:
Fifteen patients were included with a mean follow-up of 4.97 months (SD 3.05). In the thirteen patients treated with the IlluminOss without concurrent total hip arthroplasty, the mean operative time was 170.4 min (SD 90.6). The mean estimated blood loss was 52.3 mL (SD 73.7). No patients required transfusions. The mean visual analog scale (VAS) pain score at the latest follow-up was 2.29, significantly lower than the preoperative score of 9.07 (p < 0.001). Thirteen patients (92.9 %) had improved functional status at the latest follow-up.
Conclusion:
PBSS offers similar operative times, reduced blood loss, and decreased need for transfusions compared to open pelvic fixation methods. It also demonstrates significant pain reduction and improved functional outcomes without increased complications.
