Background: The sacrum is a rare location for spinal metastasis. These lesions are typically large and destructive by the time of diagnosis, making treatment difficult. When indicated, surgical stabilization offers pain relief and preserves independence in patients with impending and acute pathological sacral fractures.
Case Description: Three consecutive patients presented with sacral metastases. After either failing radiation therapy or presenting with acute fracture and instability, the patients underwent intralesional excision, bilateral L4 to ilium fusion with instrumentation, and sacroiliac (SI) screw fixation. Pain improved after surgery, and there were no wound healing complications. Two patients could continue walking without any assistive device, while one patient required a walker.
Conclusion: Stabilization with combined modified Galveston fixation and SI screw fixation relieves pain and allows maintenance of independence in patients with sacral metastasis.
