Computer Assisted Surgery and 3D Printing in Orthopaedic Oncology: A Lesson Learned by Cranio-Maxillo-Facial Surgery

Primary bone sarcomas are rare tumors and surgical resection in combination with chemo radiation therapy is the mainstay of treatment. Some specific anatomical sites still represent a reconstructive challenge due to their complex three-dimensional anatomy. In recent years, patient instruments along 3D printing technology has come innovative techniques orthopaedic oncology. We retrospectively reviewed 23 patients affected by primary sarcoma treated patient-specific custom made prostheses. At follow up after approximately two infection rate was 26%, mechanical complication 13%, local recurrence 13% (with five-years implant survival 74%). Based on our experience, custom-made prostheses represents reliable safe technique for improving accuracy tumour, particular use pelvic surgery ameliorating functional results.
