Abstract

Object. Traditionally, hemisacrectomy and internal hemipelvectomy procedures have required both an anterior and a posterior approach. A posterior-only approach has the potential to complete an en bloc tumor resection and spinopelvic reconstruction while reducing surgical morbidity. Methods. The authors describe 3 cases in which en bloc resection of the hemisacrum and ilium and subsequent lumbopelvic and pelvic ring reconstruction were performed from a posterior-only approach. Two more traditional anterior and posterior staged procedures are also included for comparison. Results. In all 3 cases, an oncologically appropriate surgery and spinopelvic reconstruction were performed through a posterior-only approach. Conclusions. The advantage of a midline posterior approach is the ability to perform a lumbosacral reconstruction, necessary in cases in which the S-1 body is iatrogenically disrupted during tumor resection.
