Pelvic Tumor Resection: When Planning Becomes Decisive

In pelvic tumor resection, the challenge is not limited to removing the tumor. It also lies in doing so without compromising key anatomical structures, in a region where surgical margins and anatomical constraints are closely intertwined.

Pelvic Tumor Resection: Managing High Anatomical Stakes

In this case, the stakes were particularly high. The objective was to preserve the sacroiliac joint, maintain the continuity of the posterior column, and secure the surgical gesture in a highly complex anatomical area.These constraints required a carefully defined and well-controlled surgical strategy.

CT and MRI Analysis for Accurate Tumor Definition

The work started with a combined analysis of CT scan and MRI data, allowing an accurate definition of the tumor extent and its true interaction with the bone.Based on this analysis, the resection plan was built with 5 mm safe margins, oncologically appropriate while avoiding unnecessary joint involvement.

Surgical Strategy Adaptation Through Planning

As discussions progressed, the initial strategy evolved toward an endopelvic approach, considered safer to limit the risk of tumor detachment and to facilitate guide positioning. The orientation of the cutting planes, particularly the most inferior one, was carefully adjusted to meet both anatomical constraints and the practical requirements of the surgical gesture.

Patient-Specific Cutting Guide for Pelvic Bone Resection

Within this context, the patient-specific cutting guide proved essential. Designed directly from the validated planning, it enabled a faithful transfer of the preoperative strategy to the operating room, ensuring precise and reproducible cutting planes.

Planning and Collaboration in Pelvic Tumor Surgery

Many thanks to the surgeon for the quality of the exchanges and the trust placed in our team .It is through this type of collaboration that preoperative planning truly shows its value in pelvic tumor resection.
