Computer-Navigated Bone Cutting in the Resection of a Pelvic Bone Tumor and Reconstruction with a Massive Bone Allograft.

ABSTRACT:

Introduction

We present here a surgical technique using a navigation system and an oscillating saw for the resection of a pelvic bone tumor combined with an allograft reconstruction.

Step 1 preoperative planning

The surgeon and radiologist together delineate the tumor on each magnetic resonance imaging (MRI) slice; then the surgeon defines target planes for tumor resection and transfers them to the allograft.

Step 2 patient positioning and surgical exposure

With the patient in the lateral decubitus position, combine ilioinguinal with iliocrural and obturator surgical approaches to expose the ilium.

Step 3 navigated tumor resection

Perform the osteotomies using the navigation system to guide the saw blade, following predefined target planes; perform a biopsy.
