Hemipelvectomy is a most radical attempt at cure of malignant tumors of the pelvis and the upper portion of the femur. Pregnancy following this severely mutilating operation is rare. Despite the considerable loss of pelvic support patients do remarkably well. A case of pregnancy following hemipelvectomy is presented and represents the 16th report in the English literature. The anatomic consequences of hemipelvectomy are described and a review of the past 61 years experience with pregnancy following this operation is presented.
