Show moreReconstructions for tumor resections in the pelvis and appendicular skeleton are among the most challenging procedures in modern orthopaedics. Limb salvage surgery is currently the treatment of choice for over 90% of patients with a primary malignant bone tumor. This thesis aims to evaluate the outcomes of various reconstructive techniques, and to identify risk factors for complications or impaired outcome following reconstruction. Part I focuses on the management of pelvic bone tumors; it discusses the management and outcome of conventional primary central chondrosarcoma of the pelvis, and two techniques for periacetabular reconstruction. Part II focuses on different types of allograft reconstructions, as well as reconstructions with modular endoprostheses, for tumors of the extremities. Show less

In case of rectal or cervical cancer, an excellent knowledge of the pelvic anatomy is essential to achieve optimal oncological and functional outcomes. This thesis describes specific parts of the pelvic anatomy that have remained controversial or have not been described from the perspective of a surgical oncological approach. In addition, a novel 3D virtual anatomical atlas was developed to create a bridge between 2D generic anatomy to in vivo surgical anatomy and to enhance patient-specific surgical planning and guidance.
