title: Reconstructive surgery using dual U-shaped rod instrumentation after posterior en bloc sacral hemiresection for metastatic tumor: case report.
abstract: Despite various complications associated with sacrectomy to remove sacral tumors, total or en bloc sacrectomy has been suggested as the most appropriate surgical treatment in such cases. The authors present the case of a 62-year-old male patient with intractable back pain and voiding difficulty whom they treated with posterior en bloc sacral hemiresection followed by reconstruction using dual U-shaped rods. They report that good spinopelvic stability was achieved without complications. The authors conclude that this technique is relatively simple compared with other sacral reconstructive techniques and can prevent complications, including herniation.
