Use of a Novel Technique for Iliac Wing Osteosarcoma Metastasis Resection and Reconstruction: A Case Report

We present the case of a 15-year-old adolescent boy with recurrent metastatic osteosarcoma to the ilium and describe the surgical technique of iliac wing wide resection with allograft reconstruction using a custom 3D-printed cutting guide that accounts for complex anatomy by enabling nonlinear osteotomies.

Use of a custom 3D-printed cutting guide to resect a circumferential metastatic focus allows for targeted lesion removal with less morbidity than unguided resection. Importantly, this novel technique improves the ease of resecting a cylindrical bone segment.
