Prior to performing a<unk> , surgeons must possess detailed knowledge of the pelvic anatomy and its relation to the pelvic tumor. Imaging studies such as conventional radiography, computed tomography, and magnetic resonance imaging help the surgeon visualize the anatomy and its relationship to the local pathology. Surgical oncology techniques are utilized when resecting tumors of the pelvis. Such techniques ensure that adequate resection margins are obtained at the time of surgery to minimize tumor recurrence. The Enneking and Dunham classification system was developed in 1978 to aid surgeons in characterizing pelvic resections. This classification scheme breaks down pelvic resections into 3 subtypes: Type I, Type II, and Type III. Type I resections involve removal of the ilium. Type II resections involve removal of the peri-acetabular region. Type III resections involve removal of the ischial and/or pubic region. Resection of pelvic bone typically requires subsequent reconstruction to ensure stability of the hip joint, particularly in internal<unk> . Examples of pelvic reconstruction include the use of an allograft, autograft, or prosthesis to bridge the remaining ends of pelvic bone following resection. Arthrodesis is a technique that can be used in internal<unk>  to fix the proximal femur to a segment of pelvic bone for the purposes of stabilizing the lower extremity.
