Novel Graft Technique for Lumbopelvic Reconstruction After Sacral Tumor Resection: A Case Report

Reconstruction after sacral tumor resection carries a high risk of nonunion and requires a slow return to weight-bearing. A bilateral iliac-crest graft, mobilized on a muscular pedicle, was used to graft and fuse the spine and pelvis after resection of a massive sacral schwannoma. Long-term follow-up and three-dimensional computed tomography imaging demonstrate rapid incorporation and solid fusion, with hypertrophy of the graft struts and excellent return to function.

This novel graft technique provides structural autograft bone that bridges the iliolumbar resection gap, providing a vascularized autograft that incorporates rapidly and reliably.
