Partial Sacrectomy With Lumbopelvic Fixation for Sacral Giant Cell Tumor: Emphasizing Optimal Neuro-Oncological Outcomes

Giant cell tumors (GCTs) of bone are classified as intermediate malignant tumors with a significant potential for local infiltration. Despite their benign histopathological appearance, these tumors exhibit extreme local aggression. The sacrum is the most commonly affected spinal region, followed by the lumbar, cervical, and thoracic regions. Active treatment of sacral GCTs is essential for preserving the sacral nerve roots and filum, allowing patients to maintain an impairment-free life. While excision of sacral GCTs enhances local control, it poses challenges, including the risk of losing bowel and bladder control. In this report, the authors share their experience with lumbopelvic fixation using gluteus maximus flaps to address the dead space following partial sacrectomy for sacral GCT in a 35-year-old female, ultimately achieving an optimal neuro-oncological outcome.
