a The 3D model of the pelvic bone shows the relationship between the tumor and the acetabulum. The area in red represents the tumor. b Multiplanar osteotomy was stimulated with the created plane to determine minimum normal bone and the absence of tumor tissue. c The resulting acetabular defect following resection to the tumor is shown
