Pelvic Tumor Surgery and Reconstruction Techniques

Pelvic tumor surgery encompasses radical excision of malignancies arising in the pelvic bones or adjacent soft tissues, often necessitating intricate resections to achieve clear margins while preserving vital structures. The complex three-dimensional anatomy of the pelvis, proximity to major neurovascular bundles and pelvic organs, and the need for weightbearing restoration pose formidable challenges. Reconstruction techniques aim to restore pelvic continuity, biomechanics and function, and to minimise complications such as mechanical failure, dislocation and infection. Approaches range from biological reconstructions using autografts or allografts to modular and patient-specific endoprostheses fabricated by advanced manufacturing methods. Preoperative planning increasingly relies on multimodal imaging, computer-assisted design and finite element analysis to optimise implant geometry and predict load distribution. Intraoperative navigation and patient-specific instruments ensure precise osteotomies and accurate implant placement. Advances in additive manufacturing permit customised lattice structures, silver coatings and hybrid solid–lattice constructs that balance mechanical strength with osseointegration. The integration of surgical guides, stereotactic navigation and dual-mobility articulations further reduces risks of recurrence and prosthetic failure. Collectively, these innovations are transforming pelvic oncology by improving functional outcomes and expanding limb-salvage options.
